- Abstract
Second-harmonic generation by femtosecond pulses in a medium with simultaneous action of the second- and third-order nonlinearities under the condition of group matching of interacting waves is analyzed. The problem is solved analytically within the long-pulse approximation, and possible generation modes are identified. In particular, it is shown that the presence of even a small second-harmonic signal (with the intensity comprising no more than 1% of that of the main wave) enables the maximal efficiency of energy conversion to be attained well before the intensities of interacting waves are increased by more than one order of magnitude due to the compression of pulses. This result is practically significant since it allows one to avoid the optical breakdown of the medium.
