Short pulse generation using semiconductor lasers

摘要

Abstract: We have generated picosecond optical pulses with very pure spectral characteristics using semiconductor lasers with monolithic cavities. For repetition rates less than 10 GHz, gain- switching of DFB lasers with quantum well loss-gratings is used. Monolithic colliding pulse mode-locked semiconductor lasers are used to generate short pulses with repetition rate up to 350 GHz.!19
