  • Micromachining of Carbon Nanocomposites with Nd:YAG and Nd:YVO4 Frequency Converted Solid State Lasers
    at focus. The beam train for the Q-switched Nd:YAG (Laser A) experimentation included a beam. expander to expand the beam to approximately 10 mm in diameter. The beam was translated using an integrated galvo. scanning head (SCANLAB hurry SCAN 14). The laser beam was focused through an f-theta lens...
  • Laser Welding Carbon Nanocomposites
    welding experimentation was setup using the Q-switched Nd:YAG integrated to a galvo scanning head. (SCANLAB hurrySCAN 14) for beam translation. The galvo head has a clear aperture of 14 mm. The laser beam is. expanded to 10 mm before entering the galvo. The galvo translates the laser beam via a set...
  • Field-testing For Environmental Pollutants Using Briefcase Sized Portable LIBS System
    system for subsurface in-situ soil. classification and the detection of heavy metal contaminates in wells. The US Army's. field-portable LIBS system included a compact probe containing of a small customized. 1.25" diameter x 14" long 17-Megawatt Nd:YAG laser head. Los Alamos National Labs,. (LANL...
  • Welding with light
    or Nd:YAG lasers to the workpiece by moving the workpiece itself, moving the laser head with a robotic arm, or by redirecting the beam with two scanner mirrors, focusing optics, or wave guides. Welding-seam width is adjustable from about /10 mm to several millimeters. Automotive parts made from...
  • Advantages of DPSS Technology
    when they arrive, you can simply plug them in and begin lasing. Generally, you'll see >95% of rated output power without any readjustment to the laser system. Ease of Conversion: You can easily retrofit a flashlamp system to utilize diode arrays. With CEO's diode pump heads, most flashlamp systems can...
  • LaserStar Workstations - The Jeweler's Tool of Choice!
    , the highest powered nd:YAG laser available. when the welding chamber is fully enclosed, the system meets the. Class 1 safety standards, which is the safest laser to operate. Custom designs in platinum. MJSA Laser Distinction Innovation award. winner. INTO THE FUTURE. During the last few years, the price...
  • Medical Device Link .
    , twin-rod (TR) technology is now available to upgrade a company?s entire JK series welding lasers. Developed by GSI Lumonics (Rugby, Warks, UK), the twin-rod oscillator design combines high beam quality with a compact laser head. Benefits include a smaller focal-spot size, greater working distances...
  • Dynamic Phase-Shifting Electronic Speckle Pattern Interferometer
    phase-shifting method in which four phase-shifted. interferograms are simultaneously generated on a single CCD array. The optical layout of the interferometer is. shown in figure 1. The test article is illuminated slightly off-axis with a high power pulsed Nd:YAG laser operating. at the second harmonic (532nm...
  • Wall Shear Stress Measurements in Two-Phase Flow using PIV, an Optical Sensor, and Wall Pressure Transducer (.pdf)
    is obtained by particle tracking velocimetry at 3.15 m downstream the. channel inlet (length-to-hydraulic-diameter-ratio= 36). An Nd:YAG laser with a wavelength of 532 nm (green light). and power of 350 mJ per pulse is utilized in the viewing area zone. The particle seeds used for tracing the flow have. small...
