Beam-Profile Effects in Self-Induced Transparency: On-Resonance Self-Focusing of Coherent Optical Pulses in Absorbing Media

  • F. P. Mattar
  • M. C. Newstein


Analytic and numerical solutions of the Maxwell- Bloch equations, including transverse and time-dependent phase variations, predict on-resonance self-focusing and elucidate its formation due to the combined effects of diffraction and inertial response of the medium. This self-focusing can be characterized by a single parameter in terms of the beam and medium parameters. Recently, two independent experiments in sodium+ and neon++ demonstrated this new self-focusing effect of spatially non-uniform self-induced transparency pulses propagating in thick resonant absorbers. Comparison of the experimental results with the theoretical analysis will be presented.

    The concept of “effective absorption coefficient has been introduced by Gibbs and Slusher in their discussion of coherent propagation in the regime where the inhomogeneous width (T2*)−1 was greater than the homogeneous width (T2)−1 but less than the inverse pulse duration (τp)−1. Under these conditions, the pulse behavior corresponds to that in a medium with a homogeneously broadened line.Google Scholar
