Abstract
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.
