Abstract

Patterns of absorption and reflection of an ultrashort laser pulse by plasma with a solid-state density, which are realized in the mode of the normal skin effect, are studied. If the pulse power is so high to provide the electron heating during the time shorter than the reciprocal fundamental frequency, a nonlinear suppression of absorption takes place and the spectrum of the reflected radiation contains odd harmonics of the fundamental frequency.
