CdSe crystals «In Stock»

Cadmium selenide (CdSe) crystals feature an infrared transmission up to 24 µm, reasonably large nonlinearity and small walk-off angle. CdSe crystals can be employed into difference frequency generation (DFG), optical parametric oscillation (OPO) schemes to generate infrared laser radiation above ZGP absorption edge (>12 µm). For instance, CdSe OPO can potentially be pumped by 2 µm Tm-doped, Ho-doped, Tm and Ho co-doped lasers and produce far infrared idler radiation. Besides nonlinear optic applications cadmium selenide crystal material can be used for IR optical elements: substrates, polarizers, waveplates, etc.
