A jet stream generating device that generates a jet stream of liquid includes: a cylindrical liquid chamber; a nozzle configured to open an end part of the liquid chamber and inject liquid F in the liquid chamber to outside; a liquid supply path configured to supply liquid F into the liquid chamber; a laser beam irradiation part configured to irradiate a pulse laser beam into the liquid chamber, and vaporize the liquid F in the liquid chamber; and a laser oscillator configured to control laser beam intensity and laser beam pulse width independently. An inner surface of the liquid chamber has a mirror plane for reflecting and guiding the pulse laser beam emitted from the laser beam irradiation part to the end part of the liquid chamber, and an adjusting part configured to adjust a distance between the nozzle and the laser beam irradiation part is included.

Jet stream generating device and jet stream generating method

A device for heating a biotissue employing a strong light, characterized in that, in thermotherapy comprising leading a biotissue to necrosis by heating the biotissue by a strong light from a light source, in order to lead a predetermined biotissue to necrosis in a temperature region before reaching tissue transpiration during the raising of the temperature of said biotissue, temperature measurement is performed by a temperature meter measuring the spatial temperature distribution of the biotissue at real time, and that the light output of the light source, the on-time of intermittent irradiation and the off-time of intermittent irradiation are controlled on the basis of the information at real time to accomplish remedial conditions.
