We experimentally demonstrate an all-fiber, ultraviolet-enhanced, supercontinuum generation in a specifically designed seven-core photonic crystal fiber pumped by a picosecond Yb-doped master oscillator power amplifier (MOPA). The MOPA source is seeded by a giant-chirped Yb-doped mode-locked fiber laser operating in the dissipative-soliton-resonance (DSR) region. The DSR is achieved by using a nonlinear optical loop mirror (NOLM) with a fundamental repetition rate of 4.5 MHz and a central wavelength of 1035 nm. An extremely wide optical spectrum spanning from 350 nm to 2400 nm is obtained with a total output power of 6.86 W.
我们通过实验证明了在一个由皮秒掺镱主振荡功率放大器（MOPA）泵浦的特殊设计的七芯光子晶体光纤中产生全光纤、紫外增强的超连续谱。MOPA源由一个工作在耗散孤子共振（DSR）区域的巨啁啾掺镱锁模光纤激光器注入种子光。DSR是通过使用一个基本重复频率为4.5MHz、中心波长为1035nm的非线性光学环形镜（NOLM）实现的。获得了一个从350nm到2400nm的极宽光谱，总输出功率为6.86W。
