Abstract

Nonadaptive changes to the basic equations is applied to the simulation of thermal blooming of focused high laser beams through the atmosphere in the report. The results show that the accuracy and speed of the computation can be improved efficiently. But it is difficult to calculate the field amplitude near the focused plane because of the beam defocus caused by thermal blooming. A modified nonadaptive-change technique is presented which overcomes the defects of the old technique, and has proven more efficient in the improvement of accuracy and speed of computation, and in the reduction of memory.
