Stimulated Raman scattering with a tightly focused pump beam.
We predict and experimentally measure the transverse spatial shapes, threshold, and ratio of Stokes to anti-Stokes radiation generated by stimulated Raman scattering of a focused Gaussian pump beam. The eigenmodes and the threshold of the scattered radiation are found to depend critically on the confocal parameter of the pump beam and the background dispersion.
