Product Detail

Technical Parameters

Measured Curve

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.

Cr²+:ZnSe can be used in numerous applications, such as free-space communication systems, target designation, time-of-flight range finding, surgery, reflectrometry, laser lidars, etc.

DIEN TECH offers Cr²+:ZnSe polycrystals which is appropriate for Q-switching of the lasers operating in the 1.5-2.1 μm spectral range.
