SrWO4 (Strontium Tungstate)

Catalog NumberOPTIX00025

CategoryRaman Laser Crystals

Description	SrWO4 is designed to serve as a high-performance Raman functional crystal, characterized by a substantial Raman gain coefficient and a robust damage threshold. This makes it an excellent medium for generating Raman lasers across a range of wavelengths, from ultraviolet to mid-infrared, depending on the pump wavelength. By extending the laser wavelength range, SrWO4 significantly enhances the versatility and application scope of laser technologies. In recent years, it has demonstrated exceptional effectiveness in applications such as liDAR and Raman laser systems.
