Lasing Medium | |||
Your choices are... | |||
Argon | A gas laser capable of delivering several watts of laser energy in the blue-green region of the visible spectrum. It requires high-power input and a very high discharge current. The visible lines at which argon will lase are: 454.6 nm; 457.9 nm; 465.8 nm; 476.5 nm; 488.0 nm; 496.5 nm; 501.7 nm; 514.5 nm; 528.7 nm. | ||
Argon / Krypton | Mixtures of argon and krypton are sometimes referred to as "white light" lasers because of the coverage over the visible spectrum the combination of the two elements produces. | ||
Krypton | A gas laser capable of delivering several watts of laser energy in the visible spectrum. It requires high-power input and a very high discharge current. The visible lines at which krypton will lase are: 406.7 nm; 413.1 nm; 415.4 nm; 468.0 nm; 476.2 nm; 482.5 nm; 520.8 nm; 530.9 nm; 568.2 nm; 647.1 nm; 676.4 nm. | ||

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. | ||
![]() | |||
Multi-Line Output | The laser output consists of two or more coherent wavelengths. | ||
Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

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. | ||
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. | ||

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.

![]() | ||
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. | ||
