Supercontinuum Generation in Photonic Crystal Fiber by Femtosecond Pulses Laser

Zhang Jun Wei Zhiyi Wang Zhaohua Zhao Linghui Qiu Yang Nie YuxinShen Naizheng Zhang Jie (Institute of Physics, The Chinese Academy of Sciences, Beijing 100080) (Received 25 October 2002; revised 15 January 2003)  
Supercontinuum light with a spectrum covering visible range was generated in a photonic crystal fiber launched by the 25 fs laser pulse train from a Ti∶sapphire laser oscillator at 800 nm wavelength. The fiber has a core diameter of ~1.8 μm and a length of 10 mm. By setting the laser energy at 2.5 nJ, it corresponds a peak power of about 0.1 MW, respectively, coupling efficiency of 17% was demonstrated.
