چکیده انگلیسی
By copropagating a fundamental pulse and a blue second-harmonic pulse from a Ti:Sapphire oscillator in a photonic crystal fiber (PCF), the spectral broadening of the blue second-harmonic pulse from 380 to 600Â nm has been observed by use of induced-phase modulation (IPM) at a 78-MHz repetition rate. From the experimental and the calculated delay time dependence of spectral intensities, it was inferred that the largest spectral broadening was observed when the second-harmonic pulse interacted with the fundamental pulse near the input end of a PCF, where the fundamental pulse was compressed temporally due to self-phase modulation and negative group velocity dispersion. From the simulation, the mechanism of spectral broadening was clarified and the fission process of the fundamental pulse was shown to be influenced strongly by IPM.
