Krekov, L. Shamanaeva] The results of an experimental study of the parameters of acoustic radiation generated by a laser spark made by focusing of a CO2 high-power pulsed laser radiation outdoors in a slightly dusty atmosphere are presented. An analysis of the acoustic pulse spectrum shows that the position of its maximum is determined by the local plasma-formation radius, and the position of its low-frequency minimum is determined by the laser spark length. A new method of laser spark diagnostics in real time is suggested that enables one to estimate the plasma-formation size distribution function and the transmission factor for laser radiation propagated in the atmosphere under conditions of laser breakdown. The results obtained are in agreement with the available experimental data. Plenum Publishing Corporation, 2000 Krekov G.
