Abstract

Experimental investigations of inversion formation dynamics in the iodine laser pumped by shock wave front radiation were performed. Vacuum ultraviolet (VUV) radiation presence in the pumping spectrum is shown to cause substantial reduction of the inversion in the region just before a shock wave. A supposition is stated that probable mechanism of this phenomenon is quenching of excited iodine atoms by an unknown substance generated during VUV photodissociation of iodides. The ways of active medium protection against VUV radiation by condensed-matter and gaseous spectral filters are suggested.
