Abstract

Ponderomotive force initiated laser self focusing can be enhanced by relativistic electron motion in a laser plasma. We derive the nonlinear refractive index due to relativistic effects and find that relativistic self focusing becomes important for a 0·25 μm laser when the laser intensity exceeds 5 × 1018 W/cm2.
