Laser Safety


The acronym LASER stands for "light amplification by the stimulated emission of radiation." Lasers are devices that produce light at very specific frequencies of the electromagnetic spectrum. The frequency of a laser depends on the type of material that is stimulated. The properties of lasers are similar to those of the other members of the electromagnetic spectrum. However, lasers can achieve great power densities which, along with operating at a single wavelength, has made them indispensable in today's marketplace. Lasers can also present a serious danger to the eyes and skin. Care must be taken to assure the safe operation of lasers.

Our department uses Class 3b and Class 4 lasers.  Due to the hazards to eye and skin exposure, proper eyewear must be worn and engineering controls installed.  Our lasers are inspected annually by EHS and continuously by our research teams.
