Thermooptical laser generation of sound in the atmosphere. Optoacoustic sensing system “Eva”
A systematic approach to the study of thermooptical laser generation of sound pulses in the atmosphere, including theoretical background, experimental investigation, verification of obtained experimental results, and its practical application is presented. The proposed approach is being developed at the Tomsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences; moreover, it has not only been tested, but also has been implemented in the optoacoustic sensing system “Eva” intended for optoacoustic remote sensing of the spatial and energetic parameters of high-power laser beams propagating in the under breakdown mode in the atmosphere, including the effective beam radius, divergence angle, laser radiation absorption coefficient, total laser energy per pulse, laser energy density, and integral transmission of pulsed laser radiation on atmospheric paths. A comparison of the results of optoacoustic sensing with bolometric data showed their good agreement.
