Self-Focusing of Laser Light and Interaction with Stimulated Scattering Processes

Abstract
The intensity distribution of intense light beams was investigated in liquids. In CS2 the diameter of the beam decreases from 700 to 5 μ when the laser power increases from 10 to 100 kW, in good agreement with theory. It is found that both stimulated Brillouin and backward-traveling stimulated Raman scattering terminate the duration of the self-focusing process.
