Abstract:

This paper presents an express technique for determining the diffusion coefficients of chromium in ZnSe, using a Tm:YLF laser that emits at 1.908 μm. The diffusion coefficients of chromium in ZnSe obtained by deposition from the vapor phase are determined to be D 9.5 0.6 × 10−9 cm 2∕s and D 1.0 0.1 × 10−9 cm 2∕s at 1100°C and 900°C, respectively. The absorption cross section of Cr 2 ions in zinc selenide at 1.908 μm was 4.6 × 10−19 cm 2.
