SFG10 Filter Glass Excellent Light Absorption Characteristics Brown Color

Diffuse-reflection pumping cavity

SFG-silicate glass is used as a fillter to prevent the color centers and reduce the thermal effects in the laser medium.

SFG-silicate glass has a strong absorption at the emission peak of Nd3+,which is helpful to reduce the radial ASE and structure, uniform pumping distribution and high pumping efficiency are achieved, which is very important for good beam quality.

This kind of pumping cavity is a perfect choice for high-energy laser system with high repetition.
