摘要

We report the fabrication of cascaded photonic crystal fiber (PCF) tapers in monolithic design.Flat broadband supercontinuum (SC) generation in cascaded PCF tapers pumped by sub-nanosecond pulses from a 1064-nm microchip laser is demonstrated.The spectral width (20 dB) extends from 0.47 to 1.67μm.In the optimal configuration,an ultraflat (3 dB) spectrum from 500 to 1 000 nm is achieved.
