Abstract

A theory describing the spectral characteristics of Raman lasers is presented. The foundation of the theory is anchored in the probabilistic nature of light-matter interactions. The Raman gain spectrum is predicted for the cases when the pump laser is oscillating in both a single longitudinal mode and multi-longitudinal mode configuration. The gain profile predicted in the two previous cases are shown to be equivalent to homogeneously and inhomogeneously broadened laser transitions, respectively. This theory is necessary to predict the behavior of Raman lasers when injection-seeding, mode-locking, or multi-frequency operation is desired. Detailed calculations are performed for the case where the pump laser medium in Nd:YAG and the Raman medium is Ba(NO₃)₂.
