Abstract:
High brightness tapered lasers emitting around 650 nm were developed. We realized 2-mm-long devices with 750-µm straight section, 1250-µm tapered section, and 4° taper angle. The input currents into both sections were independently controlled. The laser reached 500-mW output power in continuous- wave operation in a nearly diffraction-limited beam quality. A modulation efficiency of 7.5 W/A was achieved.
