Abstract

Many theories have been proposed addressing the fundamental question of optical field effect (optical tunnelling) during multiphoton ionization of atoms by very intense laser radiation [1, 2]. Often used as an indicator is the Keldish parameter γ [l], which varies from much larger than unity to much smaller, as one goes from pure multiphoton ionization to tunnelling effect.
