self-focusing – limit, Kerr lens, collapse, filamentation, optical …
Due to a Kerr lens, an intense light pulse propagating in a nonlinear medium can experience nonlinear self-focusing (or self-focussing): the beam radius is decreased compared with that of a weak pulse. The physical mechanism is based on a Kerr nonlinearity with positive χ (3).
In beam propaga-tion, self-focusing and self trapping lead to lowering of thresholds for other nonlinear processes, such as stimulated Raman and Brillouin scattering, self-phase modulation, and optical damage.
