Vertical Design Approach for Suppressing Power Saturation in GaAs-Based High-Power Diode Lasers

High-power GaAs-based diode lasers are the most efficient light sources and thus used in many industrial applications. Higher peak output power ( P opt ) and efficiency ( η E ) are sought to reduce operating cost (€/W) [1] , but P opt is limited by a range of interacting saturation mechanisms. Improved experimental diagnosis of the dominant effects with lateral and longitudinal hole-burning effect...
