Q switched DPSS infrared laser
ZnS / ZnSe, 2.29 µm
IPG Photonics Corporation
Co2+:ZnS, Cr2+:ZnS and Cr2+:ZnSe saturable absorbers (SA) are ideal materials for passive Q-switches of eye-safe fiber and solid-state lasers operating in the spectral range of 1.5-2.1 µm.
These lasers are used in numerous applications such as free-space communication systems, target designation, time-of-flight range finding, surgery, reflectrometry and laser lidars.
IPG offers a large variety of diffusion-doped Co2+:ZnS, Co2+:ZnSe, Cr2+:ZnS and Cr2+:ZnSe polycrystals appropriate for Q-switching of the lasers operating in the 1.5-2.1 µm spectral range.
