抄録

We report an external-cavity technique to simultaneously suppress the bandwidth and the divergence for a high-power laser-diode array, which features a stripe mirror and a volume Bragg grating. Using this technique, we have effectively suppressed the bandwidth from 1.81 to 0.91 nm and the divergence (1⁄e²) from 7.5° to 2.3° with an output peak power of 9.3 W.
