Lasing Medium | |||
Your choices are... | |||
Alexandrite | Alexandrite, the common name for chromium-doped chrysoberyl (Cr3+ : BeAl2O4), is a solid-state crystal. It is a four-level, low-gain, and broadly tunable laser (nominal range 700-820 nm) using the energy levels of trivalent chromium in the crystalline host. | ||
Nd: Yag | A solid-state laser using yttrium aluminum garnet as the matrix material, doped with neodymium (Nd:YAG). It can have wavelength outputs of 1.064 µm, 532 nm, 473 nm, 355 nm, or 266 nm. | ||
Nd: YVO4 | A solid-state laser using a Yttrium Orthvanadate crystal as the matrix material, doped with neodymium (Nd:YVO4). It can have wavelength outputs of 1.064 µm or 532 nm. | ||
Nd: YLF | A solid-state laser using a LiYF4 crystal as the matrix material, doped with neodymium (Nd:YLF). It can have wavelength outputs of 1.313 µm, 1.053 µm, 527 nm, 523 nm, 351 nm, or 263 nm. | ||
Ti: Sapphire | A solid-state laser using sapphire as the matrix material, doped with Ti. It can have wavelength outputs of 700 nm-1.020 µm. | ||
Other | Any other lasing material not listed. | ||

Laser Output: | |||
Your choices are... | |||
Continuous Wave | The laser output is continuous. | ||
Q-Switched | A device used to rapidly change the Q of an optical resonator. It is used in the optical resonator of a laser to prevent lasing action until a high level of inversion (optical gain and energy storage) is achieved in the lasing medium. When the switch rapidly increases the Q of the cavity, a giant pulse is generated. | ||
Pulsed | The laser output is pulsed. | ||
Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
Wavelength Range | The wavelength(s) the laser produces. | ||
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 Power | Laser power is measured in watts (W) and indicates the strength of a laser beam. A watt is one joule of energy per second. | ||
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 Performance

Operating Voltage | Operating voltage is the laser's supply voltage. | ||
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. | ||
Operating Current Range | Operating current range is the range of current over which the laser is designed to operate. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
Operating Temperature Range | Operating temperature range is the range of temperature over which the laser is designed to operate. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
Features

Features | |||
Your choices are... | |||
Array | Laser arrays contain multiple lasers. | ||
Fiber Pigtailed | Lasers have an optical-fiber pigtail that is aligned and attached precisely for optimum coupling efficiency. | ||
Internal Power Supply | The power supply is built into laser's housing. | ||
Multi-Line Output | The laser output consists of two or more coherent wavelengths. | ||
Polarized Output | The laser output is polarized. | ||
Thermoelectric Cooling | For better performance, the laser uses a thermoelectric cooler, a solid-state device which converts current into a temperature difference between two junctions. These thermoelectric junctions can be connected in series or in parallel to increase their overall temperature drop or power. | ||
Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
Beam Specification

Beam Area | Beam area refers to the area of the beam when exiting the laser. | ||
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. | ||
Beam Divergence | Beam divergence refers to the change in beam diameter as a function of distance from the laser. | ||
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. | ||
CDRH Classification
The Center for Devices and Radiological Health (CDRH), a part of the U.S. Food and Drug Administration (FDA), has a laser safety classification scheme.
Back to Top
Your choices are... | |||
Class I | Class I lasers are not hazardous for continuous viewing, or are designed to prevent human access to laser radiation. Class I lasers include both low-power lasers and embedded, high-powered lasers. Applications include laser printers. | ||
Class II | Class II lasers emit visible light which, because of the normal human aversion response, does not normally present a hazard. If viewed directly for extended periods of time, however, Class II lasers can cause eye injuries. | ||
Class IIa | Class IIa lasers emit visible light that is not intended for viewing, and that under normal operating conditions will not injure the eye if viewed for less than 1000 seconds. Barcode scanners use Class IIa lasers. | ||
Class IIIa | Class IIIa lasers will not normally injure the eye if viewed momentarily, but present a hazard if viewed using collecting optics. | ||
Class IIIb | Class IIIb lasers present an eye and skin hazard if viewed directly. This includes both intrabeam viewing and specular reflections. Class IIIb lasers do not produce a hazardous diffuse reflection except when viewed at close proximity. | ||
Class IV | Class IV lasers present an eye hazard from direct, specular and diffuse reflections. In addition, they may pose a fire hazard and burn skin. | ||
Other | Other unlisted CDRH classifications. | ||
Search Logic: | Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
