Zusammenfassung:Experimental results are presented on the development of a radiation source emitting at a wavelength of 4.775 mu m with a pulse energy up to 50 mJ and an average power up to several watts in short pulse trains. A TEA CO sub(2) laser and a nonlinear converter based on a ZnGeP sub(2) crystal, which are specially designed for these experiments, are described. The main limitations of nonlinear conversion and possible ways to overcome these limitations are considered.
