Theory of a far-off resonance mode-locked Raman laser in H-2 with high finesse cavity enhancement

摘要

We present a theory for far-off resonance mode-locked Raman lasers in H-2 with high finesse cavity enhancement. The theoretical derivation for the mode-locked Raman laser is based on a time-dependent continuous-wave (cw) Raman theory. Numerically calculated results, including the Stokes threshold and intracavity fields's amplitude and phase evolution are discussed in three different regimes depending on the relations between the coherence dephasing rate gamma(31) and the repetition rate Omega of the mode-locked pump laser. The threshold results from the mode-locked pump cases are compared with the cw, single-mode pump field case. (c) 2007 Optical Society of America.
