Introduction
Strontium tungstate (SrWO4) crystals is a superior Raman functional crystal with large raman gain coefficient and high damage threshold. It can generate corresponding raman lasers within the ultraviolet to mid-infrared range based on the pump wavelength, effectively expanding the laser wavelength. In recent years, it has shown good application performance in liDAR and Raman lasers.
