Wavelength tunable femtosecond pulse trains from a direct space-to-time pulse shaper

Summary form only given. The direct space-to-time (DST) pulse shaper has recently been shown to be useful for the generation of trains of femtosecond pulses, and "pulse packets". The direct correspondence between spatial masking elements at the apparatus input and pulses in the output temporal intensity profile is fundamentally different than the well-known Fourier-transform (FT) pulse shaping geometry and lends itself to the generation of extremely high-rate (in excess of 400 GHz) TDM signals. We show how this fast TDM signal can be obtained at multiple center wavelengths, in principle simultaneously.
