AgGaS2 and AgGaSe2 Crystals

Manufacturer's part number :


Manufacturer Altechna


Description :

AgGaS2 crystal is transparent from 0.53 to 12 µm. Silver Thiogallate (AgGaSe2) crystal has a high non-linear coefficient, high damage threshold, and a wide transmission range. It also has low optical absorption and scattering, low wavefront distortion. Among commercially available crystals, AgGaS2 has the highest figure of merit for non-linear interactions in the near and deep infrared. AgGaSe2 crystal has band edges at 0.73 and 18 µm. Its useful transmission range within 0.9-16 µm and wide phase matching capability provide excellent potential for OPO applications when pumped by a variety of currently available lasers.
