Study of a Laser on the Basis of a YSGG : Cr~(3+), Nd~(3+) Crystal with a Ring SBS Mirror

摘要

A solid-state laser with a ring SBS mirror was designed for the first time and its parameters were experimentally studied. The dependence of the efficiency of a ring SBS mirror on the amplitude isolation introduced between this mirror and the resonator of the initial laser and on parameters of the ring scheme, namely, the feedback factor and the loss on a round trip along the ring, was studied. An SBS mirror with optical feedback was shown to have an advantage over a conventional SBS mirror excited in a single passage through a nonlinear medium.
