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.
