Self-focusing collapse distance in ultrashort pulses and measurement of nonlinear index

Not Accessible

Your library or personal account may give you access

Abstract

We analyze the method of moving focus to determine the critical power for self-focusing by means of numerical simulation and a semianalytical model. It is shown that the original interpretation of a moving focus experiment does not hold in general and that inclusion of defocusing effects due to free electrons is necessary to relate the measured data to critical power.
