Abstract
Based on the optical model of the Earth atmosphere developed by the authors, the numerical simulations of the propagation effectiveness of intense radiation of different laser sources in the near- and mid-IR spectral ranges on high-altitude slant optical paths are carried out. Different laser sources, including chemical oxygen-iodine laser (COIL), chain chemical DF laser, and carbon-oxide (CO) laser are considered upon different optical weather conditions taking into account linear and nonlinear optical effects. We show that in terms of the net laser power transmitted along a path, the most preferable is the use of a COIL source because of low atmospheric linear attenuation and minimum influence of nonlinear effects. This laser source also demonstrates the best performance in terms of the mean radiation intensity at the receiver plane. Among multispectral chemical lasers, DF lasers take the first place when comparing the power transfer function.
