Method for coupling a laser beam into a liquid-jet

摘要

Reliable coupling of a high-power laser beam into a liquid-jet in a liquid-jet guided laser system can be achieved with high lifetime performance of the nozzle and the protection window, through setting the parameters of the liquid-jet guided laser system according to an optimum relationship that links the focus point of the laser, the focus cone angle, the laser beam energy distribution profile and the nozzle geometry.
