| Outline of Final Research Achievements |
Short optical pulse generation technique at high repetition rate from a CW LD based on electro-optic modulators has been developed. With a single-mode fiber for pulse compression, we could achieve the generation of 230-fs short optical pulses at 25 GHz.we demonstrated that an ultralow-phase-noise millimeter-wave and microwave generation by using our developed optical source. In addition, we could also achieve broadband dual-comb spectroscopy for H13C14N gas and liquid samples.
