Abstract

The creation of a high-intensity source in the 4.6–5.4-µm range is a problem that has attracted the attention of researchers for several decades. This paper describes the optimization of the process of generating the second harmonic of the radiation of a pulse-periodic TEA CO<sub>2</sub> laser by choosing a nonlinear crystal and the temporal shape of the laser-pump pulse. Energy-conversion efficiency of up to 20% has been experimentally obtained in a ZnGeP<sub>2</sub> crystal with mean power of the radiation in the λ=4.8µm region of up to 0.24 W and a pulse repetition rate of 10 Hz.
