摘要

The temperature and concentration quenching of the luminescence of Cr~(2+) ions in Cr:ZnSe crystals is experimentally investigated and the radiative lifetime of the upper lasing level is determined. The values of the cross sections of absorption from the ground state of Cr~(2+) ions in Cr:ZnSe crystals are refined. It is shown that the absorption from the excited state of Cr~(2+) ions is negligible near 1.5 (mu)m. Lasing in Cr:ZnSe single crystals is implemented with an efficiency of 31percent and an output power of 186 mW using laser diode pumping at a wavelength of 1.77 (mu)m.
