Abstract

The high-power diode-laser industry is dependent on highly qualified production output for fast axis collimation (FAC) lenses in scalable quantities. Not only controlled production processes but also the optical qualification of the final FAC product contribute to this goal. The product qualification approach chosen is based on diode laser collimation by active alignment and automated positioning of the FAC in collimation for the fast axis and imaging in the slow axis, allowing to evaluate the collimation performance with a specific and installed diode laser on individual emitter intensity profiles. We present the automated setup with results for corresponding sensitivity and repeatability analysis for the measurement of residual divergence.
