Abstract：Photonic crystal fiber femtosecond laser system with improved average power and pulse contrast has been studied. The photonic crystal fiber based on new material is developed. Ultra-broadband frequency tuning from visible to mid infrared has been achieved with the photonic crystal fiber laser source. Average power enhancement for THz generation has also been observed via a microstructuredGaP crystal pumped by the photonic crystal fiber laser source.

Key Words：Femtosecond Laser；Photonic Crystal Fiber；Frequency Tunable
