Spectral Line-by-Line Pulse Shaping

In this paper, we review spectral line-by-line pulse shaping, including examples of waveform generation, data demonstrating sensitivity to comb offset frequency, and requirements for high fidelity waveform generation. In order to achieve spectral line-by-line pulse shaping, we have improved the spectral resolution of grating-based pulse shapers to ~2.5 GHz, and performed experiments utilizing high repetition rate (~10 GHz) pulse sources, including harmonically mode-locked fiber lasers and strongly phase modulated CW lasers.
