Abstract
Systems and methods for the protection of optics are provided. In one example embodiment, a laser processing system is provided, the laser processing system comprising a laser source and an optic. The laser processing system may further comprise at least one of a liquid delivery mechanism configured to deposit liquid on the optic and an evacuation mechanism.
Claims16
A method for protecting laser optics, comprising:
- providing a laser processing system for delivering a pulse of laser energy to a target surface, the laser processing system including an optic to be protected;
- applying a flow of liquid to a surface of the optic, via a liquid delivery mechanism;
- allowing the liquid to stagnate upon the surface of the optic such that the liquid is not flowing a period of from about two seconds to about eight seconds;
- transmitting the pulse of laser energy through the optic and the stagnant liquid and onto the target surface;
- and
- evacuating the liquid from the surface of the optic.

A method for protecting laser optics, comprising:
- providing a laser processing system for delivering a pulse of laser energy to a target surface, the laser processing system including an optic that is spaced apart from the target surface by a distance of from about 0.5 inch to about 7 inches;
- applying a flow of liquid to a surface of the optic which is proximate the target surface;
- allowing the liquid to stagnate upon the surface of the optic such that the liquid is not flowing for a period of from about two seconds to about eight seconds;
- transmitting the pulse of laser energy through the optic and the stagnant liquid and onto the target surface;
- and
- evacuating the liquid from the surface of the optic.
