Abstract

We report a low coherence supercontinuum source with high-repetition rate and compare its spectral width and coherence under conditions of different pump pulse. The repetition rate of supercontinuum source is 4GHz and the spectrum width of supercontinuum is nearly 400nm. The supercontinuum spectral width and coherence under different pump pulse duration were compared, which indicates that with the same pump power, as the pump pulse duration increases, the width and coherence of the supercontinuum both decreases. We also compare the coherence of the supercontinuum with different pump power, as the pump power increases, the coherence of the supercontinuum deteriorates. The coherence of supercontinuum is related to pulse width and power of injected pulse.
