Type
   Beam Delivery Component:       
   Your choices are...         
   Beam Bender / Mirror Block       Beam benders or mirror blocks are used to steer laser beams in a perpendicular direction. Hardware assemblies or optical devices such as mirrors are capable of changing laser beam direction. They are used to re-point the beam and in “folded,” compact delivery systems. 
   Beam Collimator       Beam collimators are lenses or optical devices that convert divergent rays (white, or natural, light) into parallel rays (coherent light). Collimated light rays allow a sharp image of the object to be focused at the focal plane of the lens.   
   Beam Expander       Beam expanders increase beam diameter and reduce divergence, resulting in a smaller, focused spot and increased distance between the lens and part. 
   Beam Pipe / Tube       Beams pipes and tubes contain and shield the laser beam. 
   Beam Shutter / Dump       Beam shutters are manual or electronic (solenoid actuated) mirrors that divert the laser beam into a beam dump. Beam dumps consist of a laser beam-absorbing material, which is usually water-cooled to dissipate energy. 
   Beam Splitter       Beam splitters are used to separate a laser beam into intensity ratios of 33/67% or 50/50% without disturbing the polarization of the laser beam for multiaxis applications. Optically splitting a laser beam into two or more beams allows the system to process more than one side of a part at the same time. It also allows the system to process multiple parts, but at somewhat less power than with a multiple-output beam system. 
   Beam Switching / Galvo Mirror       Beam switching allows an incident laser beam to be directed either 90° to the incident beam or parallel to the incident beam. Galvo mirrors are used in galvanometer scanners to raster a beam across a surface. 
   Circular Polarizer / Phase Retarder       Circuit polarizers, phase retarders, and phase shifters convert the polarization of a beam from parallel to circular. 
   Fiber Optic Beam Delivery       Fiber optics and cable beam guides deliver the laser beam from the laser source to the focusing optics and/or workpiece. 
   Galvanometer Scanner       Galvanometer scanners use a mirror to scan or raster a beam across a surface. The mirror is mounted on an actuator that tilts or rotates the mirror as required. 
   Gas Assist / Laser Nozzle       Gas assists (laser nozzles, jets, and air knifes) are used to shroud and protect the lens. They improve marking, prevent oxidation, and expel molten metal. Gas assists are coaxial gases, such as oxygen, argon, or nitrogen, which may be used to achieve very high power levels for cutting certain metals. 
   Guidance Module (Flying Optics)       Guidance modules use flying optics or a traveling or motorized laser head. The sheet or part remains stationary, while the laser beam is moved across the workpiece surface through the motion of the head. There are several ways to move the laser head relative to the workpiece or sheet. These methods include robotic arms, guidance modules, or a motorized laser head mounted on an overhead gantry or cantilever frame. Laser heads may be driven with a linear motor, servo, or AC motor. 
   Laser Head / Focusing Unit       Laser heads or focusing units direct and focus the laser beam at a particular point on the sheet or workpiece. The head may also contain air or gas flow nozzles or shrouds to keep the lens clean and expel melted material from the cut. 
   Pointing Diode / Beam Injector       Pointing diodes or beam injectors are devices such as combiners that are used to inject a visible light laser into the system in CO2 lasing systems. The visible light aids in set up and tracking. 
   Reflection Isolator       Reflection isolators eliminate laser damage by preventing the laser beam from being reflected back into the laser resonator. 
   Resonator Optics       Resonator optics are used within laser resonators and include reflective and partially reflective (output couplers) components, rear mirrors, bend mirrors, and band selective optical components. In laser systems, different laser optical components are interchanged to adjust the wavelength to better cut or process specific materials. 
   Scan Lens       Scan lenses such as telecentric or F-theta (F-θ) lenses are used in laser scanning systems to maintain focus on a flat plane as the beam is rastered across the surface. 
   Specialty / Other       Other unlisted beam delivery components.

   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Laser Type:       
   Your choices are...         
   CO2       Laser cutting machines and components use CO2 lasers.  Carbon dioxide (CO2) lasers use the energy-state passage between vibrational and rotational states of CO2 molecules to give out a long infrared (IR) between 9 and 11µm wavelengths. CO2 lasers are able to maintain a consecutive high level of power and are also some of the most versatile lasers for processing applications. The active medium in a carbon dioxide (CO2) lasers consists of a mixture of carbon dioxide (9.5%), nitrogen (13.5), and helium (77%). 
   Nd:YAG / Solid State       Laser cutting machines and components use solid state lasers such as Nd:YAG or Nd:VO4.  Solid state lasers use a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing.  Solid state lasers are used in both low and high power applications. 
   Diode       Diode lasers (laser diodes) use nearly microscopic chips of gallium arsenide or other exotic semiconductors to generate coherent light in a very small package. The energy level differences between the conduction and valence band electrons in these semiconductors are what provide the mechanism for laser action. Common features to consider for diode lasers include fiber pigtailed and array configuration.  A laser diode can have an optical fiber pigtail precisely aligned and attached for optimum coupling efficiency.  In an array laser diodes are packaged as multiples.  Laser diode arrays will contain a certain number of elements (diodes) 
   Fiber Laser       Fiber lasers use optical fibers doped with low levels of rare-earth halides as the lasing medium to amplify light. Fiber lasers are constructed within an optical fiber and are similar in concept to gas lasers and laser diodes, except that a part of the fiber itself is used as the resonating cavity where the laser action takes place. A fiber laser use fiber optics to generate and deliver laser beams instead of the traditional hard optic resonator and beam delivery method. This helps eliminate many alignment, thermal, contamination, and maintenance issues. Laser and fiber optics are a system of lasers and flexible quartz or glass fibers that use total internal reflection (TIR) to pass light through thousands of glancing (total internal) reflections.

Applications & Features
   Process / Operation:       
   Your choices are...         
   3D Laser Processing       3D laser processing welds, cuts, drills, machines, surface treats and/or marks complex three-dimensional (3D) parts. The laser head or workpiece is repositioned or manipulated so that the laser beam has an open line of sight to the workpiece areas to be processed. 
   Laser Cutting       Laser cutting vaporizes material in a very small, well-defined area and is commonly used to produce two-dimensional (2D) patterns or parts from sheet metal, wood panels, plastic films, textiles, and other flat sheet materials. Laser beams are a single-point cutting source with a very small point, 0.001" to 0.020" or 0.025 mm to 0.5 mm, which allows very small cut-widths. Laser scoring is a process where the cut is made through only a portion of the material. Compared to conventional cutting methods, laser cutting provides many advantages, including:
  • There is no limit to the cutting path. The point can move in any direction, unlike other rotary cutting processes that use knives, bits or saws.
  • Laser cutting does not apply mechanical force to parts. Very soft, fragile, gummy or flimsy parts and flexible webs can be laser cut with no support. By contrast, conventional cutters may damage or shred the workpiece and/or gum or load up the tool. 
  • Laser beams always remain sharp and can cut very hard or abrasive materials.
  • Lasers can cut at very high speeds, making them useful for high-speed web slitting operations. Note that laser power limits the actual cutting speed.
  • Lasers provide good control of the depth of cut for scoring or kiss cutting applications.
 
   Laser Drilling / Perforating       Laser drilling and perforating repeatedly pulses focused laser energy at a specific material. Laser beams can consistently drill holes down to 0.004" with little or no debris. Holes with length-to-diameter ratios of up to 50 can be drilled with reliable, high quality results. Lasers can also drill in very difficult locations when mirrors are used to bend the beam. Laser drilling at very high rates, such as 1000 pulses per second or greater, is also possible. Lasers can be pulsed on and off quickly so that materials are perforated at very high speeds and the perforation pattern changed at will. Holes are drilled as fast as the laser beam is pulsed and moved from hole to hole. In some cases, laser beams can drill up to 10,000 holes per second. For example, laser-perforated computer paper has a hole pattern so fine that it is almost impossible to tell if it was sheared or torn apart. Laser micro-perforating is also useful for packaging applications by providing easy opening and breathability. 
   Laser Forming / Cladding       Laser forming or cladding deposits material onto the surface of a part or workpiece. Laser cladding of metals produces a 100% dense metallurgically bonded coating with minimal dilution and enhanced resistance to corrosion, abrasion and wear. Direct laser forming (DLF) from a powder bed and direct metal deposition (DMD) with spray-injected powder are two types of laser cladding processes. In the DLF process, a series of binder-free layers are deposited and then melted in the required pattern based on CAD data. In the DMD process, a laser melts a defined volume of a metal substance onto an existing form in layers. Metal powder is sprayed coaxially to the laser beam and melted onto the component. Minimal heat input and reduced processing time are two primary advantages of laser cladding over standard or traditional weld cladding. In specific applications, laser-cladding processes such as DLF restore parts to their original dimensions without secondary operations. Complete fabrication or repair of complex molds, tools or dies and rapid prototyping are common applications for laser forming or cladding. Surface or mold repair often requires the ability to duplicate a surface texture on a mold, and may include cladding or adding material to the fill cavities and then patterning the surface. DLF processes are better suited for the fabrication of new tools or prototypes. 
   Laser Marking       Lasers are used for marking, engraving, and etching applications for imparting labels, graduations, text, pictures, or patterns on a surface. Numerous materials can be marked such as ceramics, glass, wood, aluminum, stainless steel, and other material surfaces. Marking and engraving processes are different than scribing or kiss cutting operations. 
   Laser Soldering / Brazing       Laser soldering and brazing are processes where the joining materials, solder or braze filler alloys, are fused while the base metal or workpiece material remains unmelted. Dilution of the based metal does not occur. Soldering is a lower temperature process than brazing. 
   Micromachining / Trimming       Fine beams are required for micromachining or trimming thin film and thin film devices such as resistors. 
   Tube Processing       Tube processing applications include seam welding, butt welding, tube assembly fabrication, and tubing cutting. 
   Laser Heat Treatment       Laser heat treatment (sintering, ablation) rasters or focuses a laser over a specific area. Laser heat treatment is a surface modification process designed to change the microstructure of metals by controlled heating and cooling. The heat-treated area can be highly selective since lasers are able to heat treat precise areas of metals without involving the entire workpiece. The mass of the material being processed is generally sufficient for rapid heat removal or "quenching ". The enhanced mechanical properties resulting from laser heat-treating depend upon the specific composition of the metal or alloy.  Laser case hardening of transformation hardenable metals provides high wear and abrasion resistance with a minimum of distortion and cracking. Laser spot annealing of precipitation and work hardened metals, such as 300 series stainless steel and copper alloys, restores ductility and improves formability and fatigue resistance in critical areas. 
   Web Slitting / Continuous Feed       Lasers can process web materials at very high speeds in indexed (step and repeat) or on-the-fly (continuous) formats.  Many converting (cutting, slitting, perforating, kiss cutting, etc.) applications are performed on web material. In laser slitting, material on a web moves continuously under the laser beam.  The slitting process incorporates the same advantages as cutting. 
   Laser Welding       Laser welding uses an intense energy beam as its heat source.  Laser welding is accomplished at very high speeds with low heat generation and little or no distortion. Since filler materials are not required, laser welds are less bulky and more precise. Laser welds are also very repeatable because they eliminate human error. Physical materials such as electrodes or contacts are not needed in order to apply heat to the part. With their well-defined beams, lasers are excellent tools for welding thin materials, creating hermetic welds, or for use in close proximity to heat-sensitive components. Even hard to reach areas can be laser welded if a line of sight exists. All materials commonly welded by conventional means can be easily laser welded. In addition, difficult to join materials such as high carbon stainless steels and titanium may be successfully laser welded. Lasers are also used to weld dissimilar materials that may otherwise be incompatible.
