Breakup and Fusion of Self-Guided Femtosecond Light Pulses in Air
2001
Physical Review Letters
Preserved Fulltext
We show numerically for continuous-wave beams and experimentally for femtosecond pulses propagating in air, that the collapse distance of intense laser beams in a bulk Kerr medium scales as 1/P 1/2 for input powers P that are moderately above the critical power for self focusing, but that at higher powers the collapse distance scales as 1/P.
