【Abstract】 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.更多还原
