Abstract
We present measurements of cross-coherence between independent supercontinua, generated at 1550 nm. An all-fiber supercontinuum source, consisting of a femtosecond fiber laser, fiber amplifier, and highlynonlinear dispersion shifted fiber is characterized. Supercontinua generated from both 2 picosecond and 188 femtosecond pump pulses are considered. The continua generated with picosecond pulses show a degradation in coherence as the pump power is increased, whereas a high degree of cross-coherence over a broad wavelength range can be maintained when femtosecond pulses are used.Keywords
