Paper Abstract

We report the possibility of energy conversion with 95% (and higher) efficiency under the SHG of femtosecond pulse without increasing of pulse duration on doubling frequency. The main feature of the discussing regime of doubling frequency is the absence of the inverse energy conversion. This regime is realized due to cascading generation in medium with quadratic and cubic nonlinear responses at big phase mismatching and to using of compound medium. It should be emphasized that the input pulse shape on fundamental frequency is close to the soliton one. After definite section of medium, in which SHG takes place under the condition of phase matching, a medium with big phase mismatching is used.
