摘要

我们提出了一种带边频率梯度的光子晶体表面发射激光器，它可以在没有饱和吸收剂的情况下诱导自Q开关操作。我们通过实验证明，在直径为1 mm的器件中，自脉动具有创纪录的峰值功率bbb80 W和<30 ps的短脉冲宽度。

Self-$Q$-switched photonic-crystal lasers with band-edge frequency gradation

We propose a photonic-crystal surface-emitting laser with band-edge frequency gradation, which induces self-$Q$-switching operation without saturable absorbers. We experimentally demonstrate self-pulsation with a record-high peak power of > 80 W and a short pulse width of <30 ps in a 1-mm-diameter device.
