Cadmium Selenide - CdSe Crystals SKU: CdSe-0921-05
Coherent sources in the mid-IR domain have potential applications in molecular spectroscopy, biomedicine, and remote sensing. Laser systems with CdSe crystal have obvious advantage – much broader tuning range [1-3]. In the difference-mixing of the output of parametric oscillator…
