摘要
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 frequency, is demonstrated without strong wave dissipation for the cases of impact and field-induced ionization in the high-intense field range. Reflectionless propagation into the super-critical plasma and broad-band tuning of the laser radiation are emphasized as highly promising physical applications of the phenomenon described.
