SFG10 silicate glass has high UV and IR cutoff ability. It can be used as a laser cavity material for absorbing 1 micron and unwanted UV and IR radiation in high repetition rate high-energy laser systems.

Features:

  • High optical density
  • High transmittance of visible light
  • Excellent light absorption characteristics

Diffuse-reflection Pumping Cavity

Two key technologies have been used in the pumping cavity. Firstly, SFG-silicate glass is used as a filter to prevent the color centers and reduce the thermal effects in the laser medium. Moreover, SFG-silicate glass has a strong absorption at the emission peak of Nd3+, which helps reduce the radial ASE and increase the stored energy in the gain medium. Secondly, the reflector is a diffuse type. Optimizing the pumping structure ensures uniform pumping distribution and high pumping efficiency, which is very important for good beam quality. This kind of pumping cavity is perfect for a high-energy laser system with high repetition.
