The self-phase-modulation-induced spectral broadening of laser pulses in air-guided modes of hollow photonic-crystal fibers (PCF) was discussed. It was observed that this spectral broadening allowed the creation of fiber-optic limiters for high-intensity ultrashort laser pulses. It was found that the performance of PCF limiters was analyzed in terms of elementary theory of self-phase modulation. The results show that PCF had the potential as limiters for 10 MW ultrashort laser pulses and shows the possibility to switch the limiting level of output radiation energy by guiding femtosecond pulses in different PCF modes.
