Abstract
Broad area diode lasers operate with high power and efficiency but suffer from poor beam quality. Diffraction-limited lasers with equivalent power offer a disruptive alternative for applications ranging from fiber laser pumping to automotive LIDAR. We report >9 W continuous output power with 50% EO from tapered diode lasers at 885 and 980 nm, and >3 W power with 25% EO at 1550 nm. We show for the first time that beam quality degradation with increasing injection is completely mitigated and maintain a slow-axis M^2 of 1.3 from threshold to rollover. These devices achieve an order-of-magnitude increase in brightness over commercially available high power diode lasers.
