It is shown that, because of the large diameter disc and low reflectivity output mirror of high power disc lasers, its ase is more obvious than that of low power lasers.

计算表明，高功率激光器相比低功率激光器有更大的ASE，原因主要在于高功率激光器采用大直径圆盘和低反射率输出镜。

At this temperature, the mirror was able to flip between high and low reflectivity over a million times a second suggesting that, if it can be kept reliably at this critical temperature, gallium will make a fast (and also small and cheap) optical switch.
