“…Historically, the problems of laser photoacoustics have been the subject of studies by both individual scientists and scientific schools [1][2][3][4][5][6][7]. This interest is due to the fact that the effect of photostimulated generation of mechanical (acoustic) waves in radiation-exposed media is widely used for various applications.…”

“…Laser medicine occupies one of the central positions among these applications. Various areas are successfully developing here, such as high-resolution tomography [4,7], so-called 'cold' (low temperature or cavitation) laser microsurgery [1][2][3][4][5][6], and also optoacoustic control of medical treatment processes. This work is devoted to development of the physical fundamentals of a novel medical application of laser photoacoustics, namely, enhancement of the hydraulic permeability of biological tissues through their 'loosening' of sorts by cavitation microbubble fields.…”

Thermomechanical effect of pulse-periodic laser radiation on cartilaginous and eye tissues

This paper is devoted to theoretical and experimental studies into the thermomechanical action of laser radiation on biological tissues. The thermal stresses and strains developing in biological tissues under the effect of pulse-periodic laser radiation are theoretically modeled for a wide range of laser pulse durations. The models constructed allow one to calculate the magnitude of pressures developing in cartilaginous and eye tissues exposed to laser radiation and predict the evolution of cavitation phenomena occurring therein. The calculation results agree well with experimental data on the growth of pressure and deformations, as well as the dynamics of formation of gas bubbles, in the laser-affected tissues. Experiments on the effect of laser radiation on the trabecular region of the eye in minipigs demonstrated that there existed optimal laser irradiation regimens causing a substantial increase in the hydraulic permeability of the radiation-exposed tissue, which can be used to develop a novel glaucoma treatment method.
