本文报道了在1.06 μ m的NdAl_3（BO_3）_4微片激光器上实现的连续波和亚纳秒被动调Q激光振荡。只有当使用谐振泵浦（4 I 9/2-> 4F 3/2，882 nm）代替传统的4 I 9/2-> 4F 5/2（808 nm）泵浦时，才有可能实现高效和稳定的激光器操作。激光器性能的改善是由于泵浦引起的热负荷的大幅降低，这是通过直接泵浦到发射级来实现的。
We report on continuous-wave and subnanosecond passively Q-switched laser oscillation from a NdAl3(BO3)4 microchip laser operating at 1.06 microm. Efficient and stable laser operation is possible only when resonant pumping (4I9/2-->4F3/2 at 882 nm) is used instead of the traditional 4I9/2-->4F5/2 (808 nm) pumping. The improvement in laser performance is caused by a strong reduction in the pump-induced thermal loading, which is achieved by pumping directly into the emitting level.
