Product Description

Silver Gallium Sulfide (AGS)

Nature and Characteristics:
AgGaS₂(AGS) crystal is one of the most effective nonlinear laser crystals used in the infrared working band at present. Because of its large nonlinear coefficient, high infrared transmittance, low optical absorption and scattering, and low wavefront distortion performance, its application in the infrared field has been popularized more and more. At present, this kind of crystal is the best choice for the frequency doubling material of CO₂ laser with 10.6μm output.

Main Applications:
1. Used in the infrared field with large nonlinear optical coefficients and high transmittance.
2. Frequency doubling device for outputting 10.6μm CO₂ laser
3. It can be used in OPO device of  Nd: YAG laser.
4. Suitable for frequency mixing in OPO output from Nd: YAG lasers, Ti: sapphire lasers, and various dye lasers.
