Growth and characterization of mid-far infrared optical material CdSe crystal

We investigated the decomposition conditions of CdSe crystal with the aid of thermodynamics analysis. We chose the optimized growth parameters (1 MPa, 1250°C) based on the numerical simulation, and obtained single crystal boule with 28 mm in diameter and 70 mm in length. Preliminary tests showed tha...

Summary:We investigated the decomposition conditions of CdSe crystal with the aid of thermodynamics analysis. We chose the optimized growth parameters (1 MPa, 1250°C) based on the numerical simulation, and obtained single crystal boule with 28 mm in diameter and 70 mm in length. Preliminary tests showed that the crystal had fine homogeneity in composition (CdSe0.975), high infrared transmission (68-70%, 2.0-16 µm) and large laser induced damage threshold value (LIDT, 56 MW/cm2). This crystal may be a good candidate for the 8-12 µm mid-far nonlinear optical (NLO) material.
