Abstract

In deciding the laser type for operation in the atmosphere, one should adopt the generation frequencies which coincide with atmospheric windows of transparencies. For example, the iodine photodissociation lasers (PDL). Some parameters of these lasers are comparable with those of neodimium-doped YAG- or Co₂-lasers. Under real conditions of the laser operation when the mixing rate of sublevels of low working state exceeds significantly the relaxation rate of upper state sub levels, the spectrum of iodine laser consists of one component corresponding to the strongest transition 3 yields 4 ((nu) equals 7603.14 cm^-1). Such one-frequency spectrum is characteristic of PDL with solar, chemical or xenon lamp radiation pumping (only in the case of compensated magntic field).
