Here we demonstrate a supercontiuum spectrum generated in a tapered fiber pumped by a Ti sapphire laser with 130fs
pulse width at 800nm centre wavelength. The tapered fiber with the diameter of 1.25μm and the length of 16cm was
made by using a tapered machine. The supercontiuum range is from 500nm to 900nm. We simulated the
supercontinuum with the nonlinear Schrodinger Equation and discussed the affecting factors. In some conditions, the
experimental results are agreed very well with the theoretical analyses.
