We present an experimental study on low-threshold supercontinuum generation mainly based on cascaded stimulated Raman scattering (SRS) effect in a four-stage fiber master oscillator power amplifier (MOPA) system. The cascaded SRS is achieved by using a long passive fiber pumped by a pulsed fiber laser centered at 1064 nm wavelength. The cascaded SRS seed is amplified in a double-clad ytterbium-doped fiber amplifier, generating supercontinuum ranging from 960 nm to 1700 nm with 13.6 W maximum average output power and approximately 17.7 mW/nm average spectral power density.
