AGSe – silver selenogallate

AGSe – Silver Selenogallate (AgGaSe2 and sometimes known as silver gallium selenide) is widely applied in middle infrared (MIR), infrared (IR) and far infrared (FIR) light applications and it is one of the best crystals for tree-wave interactions. Large non-linear optical (NLO) coefficient allows AGSe be one of the most used infrared crystals for non-linear optics (NLO) applications.

When comparing to AGS, Silver Selenogallate (AGSe) stands out with lower absorption coefficient in infrared and lower melting point.
