The dependence of the Raman Stokes energy on the laser intensity has been investigated from the spontaneous scattering to the saturation region using a frequency-doubled Q-switched Nd: YAG laser focused into hydrogen gas. For H-2 cells longer than the laser pulse length the measured Raman amplification is in good agreement with the results of a nonorthogonal mode theory for a pin-guided amplifier. For short H-2 cells the measured Stokes energy rises more steeply with increasing laser intensity than predicted by the calculations. This result is ascribed to the feedback by diffuse reflections from the cell windows and optical elements.
