Laser Field Ionization Rates in the Barrier-Suppression Regime

  • Published:
Journal of Russian Laser Research Aims and scope

Abstract

We analyze the influence of ponderomotive and Stark shifts on the barrier suppression transition rate for noble and alkali atoms for a low-frequency linearly-polarized laser field. We consider three approaches to the barrier suppression ionization (BSI) rate: through a critical field, an ion charge, and the Airy function. We show that ponderomotive and Stark shifts affect the rate differently in these three approaches. Generally, the rate curve of K is more strongly lowered than the one of Ar.
