Abstract

See full text

The disclosure is a method and system for monitoring the condition of an optical protective component in a laser system associated with a data processor. In one embodiment, the method begins with directing light from the process head of a laser through the optical protective component onto a workpiece. A return light via the workpiece causes light signals coupled through the protective component and into to a fiber which extends proximate the protective component and thereafter flexibly to a sensor. The sensed signals allow monitoring the condition of the protective component during use. The method and system is operative for use with optical protective elements downstream of the process head.
