Microchip Lasers
Microchip lasers (microlasers) are a specific subset of q-switched DPSS lasers. These lasers utilize a passive q-switch, monolithically bonded to the laser crystal. These passive q-switches, which are typically semiconductor saturable absorber mirrors (SESAM), act as both the q-switch and the output coupler allowing for extremely small optical cavities. Furthermore, the compact and alignment-free nature of the microchip laser design allows them to be made utilizing telecom production techniques which allow for compact ruggedized packaging at a relatively low cost. As a result, microlasers are ideal for integration into range finding, scribing, and marking systems. Additionally, through the use of second, third, and fourth harmonic generation they can emit wavelengths from the ultraviolet @ 236.5nm through the infrared @ 1064nm. OEM fiber laser packages and modules are available.
