Abstract

We report a rapidly tunable, wavelength agile fiber laser system capable of the synchronous generation of sequences of pulses with different wavelengths in the visible region of the spectrum using stimulated Raman scattering of multi-step pump pulses in a 250 m length of fiber. The frequency doubled output of a single polarization all-fiber Yb-doped MOPA operating at 1060 nm was used as the pump source. By adjusting the pump power and the pulse profiles we achieved the sequential excitation of green (1st Stokes), yellow (4th Stokes) and red light (6th Stokes) using 3-step pulses, or the combination of any two using 2-step pulses. The wavelength switching time was <5ns and was limited only by the pulse shaping drive electronics.
