Abstract

The association of F-centers to CN defects in alkali halide crystals forms "FH(CN)" complexes which under excitation of their electronic absorption transitions in the visible produce optical emission from vibrationally excited CN- molecular states around 5 μm. In the host CsCl, with the most efficient F-center/CN- molecule coupling, laser oscillation has been obtained at temperatures up to 77 K on the three strongest vibrational emission transitions at 2000, 2025 and 2050 cm -1. Threshold pump powers are in the mW range.
