Microchip Lasers Overview
Microchip lasers are a specific subset of q-switched DPSS lasers where a passive q-switch is 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. The compact and alignment-free nature of microchip lasers allows them to be made utilizing telecom production techniques which allow for compact ruggedized packaging at a relatively low cost. As a result, microchip lasers 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 through the infrared. OEM fiber laser packages and modules are available.
