摘要：

We demonstrate a divergence-narrowed broad-area laser-diode array (LDA) with an external-cavity configuration that consists of a beam-transformation system and an off-axis reflecting mirror. Sixteen off-axis external-cavity laser diodes are formed for the high-power LDA. At a drive current of 21.2 A (four times the threshold current), the divergence angle full width at half maximum of the slow axis is reduced from 7.26degrees without the external cavity to 1.45degrees with the external cavity. The external-cavity LDA achieves a cw power output of 9.8 W, which is 60% of the free-running LDA. (C) 2004 American Institute of Physics.
