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

Research output: Contribution to journal › Article › peer-review

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.
