Abstract

We carry out temporally and spatially resolved measurements of the Stokes and the depleted pump beams emitted from a para-H2 Raman laser. It is confirmed that the pump beam is fully depleted even at its rim, as well as at its center, and that the corresponding Stokes beam has a nearly Gaussian profile.

Schematic representation of the experimental setup. The Stokes wave was reflected and separated from the depleted pump wave by dichroic mirror (D.M.) 1. Infrared (I.R.) filters were used for further spectral purification. A photon-drag detector, set on the movable stage, scanned horizontally across the Stokes beam. The temporal shape was obtained at an individual scanned point and was averaged for several groups of ten shots. Similar measurements were also carried out for the pump beam.

(a) Typical temporal shapes for a depleted pump beam and a Stokes beam. (b) Spatial and temporal contour diagrams of a depleted pump pulse. (c) Similar contour diagrams of a Stokes pulse. Each beam size is indicated as the width of a tenth part of the peak intensity. (d) Radial energy profile of the Stokes beam, measured with an energy meter in place of the photon-drag detector. The solid curve represents an ideal Gaussian shape.
