Gallium selenide (GaSe) crystal

non-linear opticallaser

Gallium selenide is a nonlinear optical material and photoconductor and it is mainly used for such applications as second harmonic generation of CO2-lasers, up-conversion of CO2-laser radiation image into near-IR or visible region, frequencies mixing in the middle IR region, differential frequencies generation (DFG) in the middle IR region from 5.5 to 18.0 µm
