Sound generation by laser radiation in air: application to restoration of energy distribution in laser beams

Theoretical research on acoustic wave generation by the absorption of laser radiation is reviewed. Relations between acoustic fields generated by laser beams in the air and intensity and energy distributions in cross-sections of laser beams are described for the case of finite thermalization time. It is concluded that acoustic methods might be used for the energy and power restoration of spatial distributions in the laser beams, restoration of laser radiation absorption parameters, and testing of absorption kinetic models.
