摘要：
The peculiarities of thermooptical excitation of elastic waves in nonlinear crystals, which appear due to modulated absorption of the energy from a Bessel light beam at the second harmonic, were theoretically examined. The amplitude–phase characteristics of the photoacoustic signal were found, and the conditions of the most effective thermooptical excitation of the sound were determined. The received results can be used in the design of new optoacoustic scanners for diagnostics of subsurface structures and new quantum electronics and integrated optics devices.
