Intracavity brillouin scattering from passive Q-spoiling cells.
Stimulated Brillouin scattering from the methanol solvent used in conjunction with cryptocyanine bleachable dye in a ruby laser cavity has been observed at low megawatt output powers. The frequency shifts of the Brillouin scattered radiation produced within the laser cavity are slightly less than frequency shifts produced in an external methanol cell. The Brillouin radiation was eliminated even at output power levels in excess of 250 MW when a 3-mm length cell was used in place of the 25.4-mm commercial cell.
