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% E/O from tapered diode lasers at 885 and 980 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 are suitable for use as the building block of geometrical, spectral, and coherent beam combined arrays.
