Twin-Contact 645-nm Tapered Laser With 500-mW Output Power

High brightness tapered lasers emitting around 650 nm were developed. We realized 2-mm-long devices with 750-mum straight section, 1250-mum tapered section, and 4deg taper angle. The input currents into both sections were independently controlled. The laser reached 500-mW output power in continuous-...
