Self-focusing Distance of Very High Power Laser Pulses.

چکیده
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.

متن کاملOn the interferometric coherent structures in femtosecond supercontinuum generation
Mechanism of SC generation is not fully understood as at such high laser powers interplay among several competing mechanisms occurs. Self-phase modulation (SPM) [2, 5, 7, 14, 15] associated with self-focusing is considered to be the trigger for the drastic broadening of ultrashort pulses. The intensity-dependent “induced Kerr-nonlinearity” of the dielectric medium and the beam shape causes the ...
متن کاملHigh-power regime of femtosecond-laser pulse propagation in silica: multiple-cone formation.
We present a numerical study of the (2+1)-dimensional propagation dynamics of femtosecond-laser pulses in silica. In particular, considered are pulses, whose power is tens to hundreds of times higher than the threshold for self-focusing. We solve the axially symmetric, extended, nonlinear Schrödinger equation for the laser electric field, including group velocity dispersion, Kerr nonlinearity, ...
متن کاملIonization-induced self-compression of tightly focused femtosecond laser pulses.
As lasers become progressively higher in power, optical damage thresholds will become a limiting factor. Using the nonlinear optics of plasma may be a way to circumvent these limits. Here, we present a new self-compression mechanism for high-power, femtosecond laser pulses based on geometrical focusing and three dimensional spatiotemporal reshaping in an ionizing plasma. By propagating tightly ...
متن کاملParticle-in-cell simulations of high energy electron production by intense laser pulses in underdense plasmas
The propagation of intense laser pulses and the generation of high energy electrons from the underdense plasmas are investigated using two dimensional particlein-cell simulations. When the ratio of the laser power and a critical power of relativistic self-focusing is the optimal value, it propagates stably and electrons have maximum energies.
