GaAs-based 9xx-nm broad-area diode lasers (BALs) offer the highest optical power (Popt) among diode lasers and the highest conversion efficiency (¿E) among all light sources. Therefore, they are widely used in material processing applications (e.g. metal cutting), which additionally require high beam quality (i.e. low beam parameter product BPP), typically limited in BALs along the lateral axis (BPPlat). Enhancing BAL performance is dependent on identifying the thermal and non-thermal limiting mechanisms, and implementing design changes to minimize their effects. In this work, two novel appro...
