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.
