Nonlinear Optical Material GaSe Used For Frequency Doubling Of CO2 Laser With Conversion Efficiency Of 9%
Products Description:
GaSe crystal (selenium selenide crystal) is a nonlinear optical material mainly used for frequency doubling of CO2 laser with conversion efficiency of 9%. Converting CO2 laser radiation to visible or near-infrared, medium-wave infrared mixing study. However, the GaSe crystal cannot be cut to a certain phase angle because the material structure <001> of the GaSe crystal limits this cut.
