Abstract

The results of experimental investigations of temporal characteristics of an acoustic pulse formed at various regimes of thermal interaction between CO₂-laser high-power pulses and small volumes of an absorbing liquid are submitted. A connection between the shape of the generated pressure pulse and regimes of laser radiation interaction with a substance is established. The model of pulsing sphere is applied to interpretation of the received dependence of characteristics under study on the laser energy density. The comparison of computed and experimental data is carried out. The results of measurements of the acoustic response are submitted with propagation of a laser pulse on an atmospheric path. The opportunity of use of an acoustic method for search of laws is discussed with formation in an atmosphere of a long laser spark.
