Phase locking of holographic solid-state Nd-lasers via four-wave-mixing in saturable-gain media

In this paper, a parallel-coupling laser system based on two self-phase-conjugated Nd:YAG lasers with phase locking in addition active rod chamber is demonstrated. The phase, frequency and amplitude locking of the radiation of two self-adaptive lasers is realized by the degenerate four-wave mixing o...

Description
Summary:In this paper, a parallel-coupling laser system based on two self-phase-conjugated Nd:YAG lasers with phase locking in addition active rod chamber is demonstrated. The phase, frequency and amplitude locking of the radiation of two self-adaptive lasers is realized by the degenerate four-wave mixing of intracavity beams in the dynamic holographic transmission gain gratings formed in the additional pumped laser rod. Lasing dynamics of the proposed system was studied theoretically and experimentally and a two-dimensional model of interaction of two single-mode beams with active medium was developed.
