Material General Description of  CdSe Crystal 

Cadmium Selenide (CdSe) crystals are a highly versatile nonlinear optical material with an extensive transparency range of 0.7 to 24 µm. Known for their positive uniaxial symmetry and large nonlinear coefficients, CdSe crystals are widely utilized in difference frequency generation (DFG) and optical parametric oscillation (OPO) for producing far-infrared laser radiation. Their small walk-off angle ensures minimized beam distortion, making them an optimal choice for critical optical applications. With high thermal conductivity and a laser damage threshold of 60 MW/cm² (10.6 µm, 200 ns), CdSe is ideal for laser systems requiring precision and durability. Photonics On Crystals (POC) ensures the highest quality standards in crystal growth and fabrication to meet diverse industry needs
