a The measured spectra of the 1st (red), 2nd (blue), and 3rd (green) Stokes lines and the cascaded Raman branches (purple and orange) by discrete tuning the pump wavelength from 1526 nm to 1620 nm. The pump power is kept below 52 mW during the wavelength sweep. b The measured Raman lasing wavelength of the five groups versus the pump wavelength.
