Abstract :
Using Onsager potential transfer differential equation of irreversible process thermodynamics. The transfer potential of gaseous medium radiated by far infrared laser has been studied and the nonlinear thermal blooming in the medium is obtained. The results of this paper indicate that the generally used method of variable separation is not applicable in solving this problem, so the method of limited integration variations is used, and the calculation corresponding to infrared laser beam are relatively satisfied in comparison to the experimental measurement
