5. 4.Conclusions We have presented an optimized high-power handing optical frequency comb generator with a broad RF tuning range from 6-18 GHz. The comb generates broad bandwidth flat-top combs having between 60-75 lineswithin 10dB. The comb stability is tested in a high-performance pulse compression experiment, where the spectral phase of the comb is corrected up to eighth order. The flexibility, robustness, and power handing features make it an ideal source for optical communications and high-performance waveform synthesis
