The thermal blooming of high-energy beams from a solid-state heat-capacity laser in the atmosphere

摘要

Based on the one-aerosol model, we investigate the influence of thermal blooming on the propagation of solid-state heat-capacity laser (SSHCL) beams in atmosphere. By employing only this aerosol model and ignoring the diffraction and atmospheric turbulence, we evaluate the change in the average transmittance when the incident intensity and the propagation distance are changed. We conclude that the effect of thermal blooming on the propagation of SSHCL beams in the atmosphere is dependent on the incident intensity and the propagation distance. As the incident intensity and propagation distance increase, the influence of thermal blooming on the average transmittance strengthens. However, when the incident intensity is not strong enough, the incident intensity barely affects the average transmittance.
