Abstract
We analyzed the effect of two-photon absorption (TPA) on distributed Bragg reflectors and applied our results to the study of saturable Bragg reflectors in mode-locked Cr:LiSAF laser. We showed that in agreement with experimental results, TPA is greatly reduced compared to bulk materials. Hence, Bragg reflectors can be successfully used in a variety of low-loss laser components. c 1997 Optical Society of America.
摘要
我们分析了双光子吸收（TPA）对分布布拉格反射器的影响，并将我们的结果应用于锁模Cr:LiSAF激光器中可饱和布拉格反射器的研究。我们表明，与实验结果一致，与块状材料相比，TPA大大降低。因此，布拉格反射器可以成功地用于各种低损耗激光元件。版权所有1997美国光学学会。
