High power laser Beam analyzer


  • Standalone High power Fiber laser Characterization System

    This system is designed for characterization of High Power Fiber laser up-to 120kW. The specifications are for the multipurpose, efficient, reliable and robust HPLBA system, which will be able to measure various laser beam parameter of a focused laser beam like laser beam divergence, focus spot diameter, focal spot movement, its M2 and its power in real time. In addition to this one CCD based Spatial profiler along with imaging lenses is also provided to do spatial profiling of a raw collimated beam in imaging mode, XYZ stage, required Mount, focusing lens, Inbuilt Processing Unit with 10-inch Touch Display and Mounting Mechanism for mounting external power meter makes unit a complete setup for doing laser beam diagnostics. System is suitable for doing focal spot analysis of laser wavelength from 980 to 1080nm with power from 1 KW to 100 KW or more with a collimated beam of diameter around 8 to 10 mm. System has the provision for attaching the Beam Dump/ External power meter which can be user provided or can be bought through us as an additional part. Complete proposal is designed keeping in mind the drawing provided with the tender specs.
