Abstract: A beam coupler alignment system for a fiber laser system is disclosed. The system includes a focus adjust collimator assembly having an inner and outer housing assembly portion. The inner assembly includes a coupler housing assembly and a modified lens housing received within and adjustable relative to via a mechanism configured and arranged to apply an asymmetric binding force in a predictable and repeatable manner. A lever assembly contacts the lens housing and exerts an off-center (asymmetric) force relative to coupler housing assembly creating a friction bind eliminating X and Y axis movement yet allowing Z axis movement with minimal effort. The assembly may further include an alignment mechanism configured and arranged to optically align an input collimator unit and an output collimator unit of a complex fiber laser system about a common optical axis using the proposed assembly.

Abstract: 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.
