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 1.67 mu m. In the optimal configuration, an ultraflat (3 dB) spectrum from 500 to 1 000 nm is achieved.
