Abstract

The performance of high-brightness laser diode emitters and bars is often affected by external optical feedback from the modules and systems in which they are deployed. We report on the coupling of an advanced simulation tool for high-brightness laser diodes with commercial optical design software. The aim of this work is to create a software tool which can be applied to the design and optimisation of high-brightness diode laser modules and systems intended for use in industrial applications requiring the cutting and welding of sheet metal.
