Abstract

Using the numerical simulation method and real atmospheric parameter modes, the effect of nonlinear thermal blooming on upward propagation of collimated pulsed high power laser beams in the atmosphere have been studied on the basis of the wave optics approach. The results show that such blooming, even though small, has critically bad effect on the laser beam front and its divergence.
