Аннотация: Cerenkov-type second harmonic generation of femtosecond pulses in random one-dimensional nonlinear photonic crystal of strontium tetraborate is investigated experimentally and theoretically. Sidebands in angular-spectral dependence of generated second harmonic were detected and found to be in perfect agreement with calculations. Spectral maximum of generated radiation experiences deviation from Cerenkov relation due to influence of nonlinear photonic crystal structure. Pulse duration and local spectrum of Cerenkov second harmonic are measured and found to be in fair agreement with each other. (C) 2012 American Institute of Physics.
