Abstract
The theory of strong frequency up-conversion of the powerful ionizing electromagnetic radiation in gases is presented based on the modified nonlinear geometrical optics approximation. The permanent spectrum up- shift versus propagation path, exceeding considerably the initial freq uency, is demonstrated without strong wave dissipation for the cases o f impact and field-induced ionization in the high-intense field range. Reflectionless propagation into the super-critical plasma and broad-b and tuning of the laser radiation are emphasized as highly promising p hysical applications of the phenomenon described.
