Picosecond pulse generation with a 1.55 μm tunable twin guide laser using blue-chirp compression

Ultrashort lightpulses at λ=1.55 μm are generated by modulating the emission wavelength of a tunable twin guide laser and subsequent compression of the linearly blue-chirped part of the output down to 3.5 ps. Its simplicity, the low jitter, and the possibility of direct triggering the pulses are the main advantages of this new method.
