We present generation of widely and flatly broadened, low-noise and high-coherence supercontinuum (SC). Pedestal-free high-power Raman soliton pulses are generated as pump pulses and a wideband and flat SC is generated in a normal and small dispersive highly nonlinear fiber. The average power and the full-width at half maximum (FWHM) bandwidth of the generated SC are 40 mW and 580 nm, respectively. The spectral shape is very flat and smooth. The flat spectrum with $\pm 1$ dB uniformity is obtained at wavelength region of 1370–1890 nm. The generated SC shows low relative intensity noise (RIN) and high degree of coherence.
