Abstract

We explain a pulse compression mechanism reported in picosecond Raman lasers pumped by continuous trains of mode-locked pulses. Our theoretical model is based on transient Raman scattering equations, and shows good agreement with the experimental results. The model reveals that the compression effect is produced by a combination of group velocity walk-off and strong pump pulse depletion. We predict the possibilities and the limitations of this technique for constructing highly efficient, low cost, ultrafast Raman lasers in the visible.
