Summary of report:

The thermal blooming of the laser beam propagating in a moving medium, the violation of Snell’s laws at reflection of intensive laser beam from a mirror located in aa non-linear medium, the math models describing these phenomena, a new method of their computer simulation are discussed in the current report. Advantages of proposed numerical method are demonstrated based on its c omparison with alternating directions method which is widely used
