Mode-Locked Ramam Laser in H2 Pumped by a Mode-Locked External Cavity Diode Laser: Author: Xiong, Yihan; Date: 2007-08-15; Program: Physics; Abstract: In this thesis, a theory is first presented for a far-off resonance mode-locked Raman laser in H2 with high finesse cavity enhancement. The theoretical derivation for the mode-locked Raman laser is based on semiclasscial laser theory and time-dependent continuous wave (CW) Raman theory. Numerically calculated results, including the intracavity fields' amplitude and phase evolution and output Stokes power versus input pump power are discussed in three different regimes depending on the relationship between the coherence dephasing rate and the repetition rate of the mode-locked pump laser.

Anti-Stokes generation in a continuous wave raman laser: Author: Murphy, Sytil Kathleen; Date: 2008-08-15; Program: Physics; Abstract: The continuous-wave Raman laser system differs from other Raman systems in that it uses cavity enhancement to augment the pump laser source rather than a high-power pulsed laser source. Through interactions of the pump laser with the Raman active medium, all Raman systems can produce both red-shifted, Stokes, emission and blue-shifted, anti-Stokes, emission. Previous, continuous-wave Raman laser systems have focused on the Stokes emission. This dissertation presents theory and data on the anti-Stokes emission. Specifically, it investigates the anti-Stokes mode structure and the emitted power a...; Download File | View full details
