Abstract
We calculate the spatiotemporal evolution of intense, femtosecond pulses that are incident upon a saturahle absorbing interface in the regime of self-reflection, using the finite-difference time-domain computational method. The pulses induce a curved, moving absorption front in the nonlinear medium that acts as a transient focusing mirror for the reflected pulse energy.
