Abstract

We demonstrate a few-picosecond pulse laser of 8-GHz repetition rate by electro-optic modulation from continuous signal. The generated pulse has a 1-nm of spectrum bandwidth and a 67-ps of pulse duration since the pulse is modulated. To compress the long pulse to few-picosecond level, a triple-pass dispersion compensator with a high-groove grating of 1800-l/mm is applied. After compression, we achieve 3-ps pulse duration, which is closed to the transform-limited pulse duration.
