As a laser beam propagates through a pipe in which the air would absorbe some energy of the laser beam, the absorbed laser energy heats the air and form a distributed thermal blooming effects along the heated air path. As it can limit the maximum power that can be efficiently transmitted through the air, thermal blooming is one of the most serious problems encountered in the propagation of laser. Many theoretical and experimental works have been concerned with it.
In this paper, based on the available r...
