On the Difference in Action of the Laser Light with Wavelength Near 2mm on Biotissue in Gas and Water Media

KnE Energy / VII International Conference on Photonics and Information Optics (PhIO) / Pages 407–418

Abstract

It is shown that unlike action in the air environment, section of the biotissue in the water environment (physiological solution) is performed by the steam-gas stream which is formed as a result of superintensive boiling in thin (about 0.1 mm) a liquid layer in which absorbed laser radiation. Coagulation of the biotissue, adjacent to a section, happens due to heat which is produced via vapor condensation.


Keywords: laser radiation in urology, a laser enucleation of the BPH, laser removal of the bladder cancer.
