High-repetition-rate picosecond pulse generation at 1.5 microm by intracavity laser frequency modulation.
We propose and experimentally demonstrate generation of transform-limited pulse trains at a 2.5-GHz repetition rate from a frequency-modulated erbium-ytterbium bulk glass laser by using an intracavity lithium niobate phase modulator and an external fiber Bragg grating filter. Light pulses with durations tunable from 40 to 80 ps and 0.2-mW fiber-coupled average power at 1535 nm have been obtained.
