In this work, ultrashort pulse generation based on optical fiber coupled distributed feedback (DFB) laser diode and pulse regeneration technique is presented. Two-stage Mamyshev filtering, double-pass amplification in the first stage, and a tunable filter are used to achieve output pulses of 3.6 ps duration from the gain switched DFB diode with no additional pulse compression at the source output. Optimization of spectral broadening and isolation of initial pulse core components are achieved by a tunable spectral filter within a fiber. The resulting pulses are characterized by highly sensitive frequency resolved optical gating (FROG). The concept is compatible with today’s requirements for pulse on demand operation as it enable precise synchronization with external systems. Further, its architecture offers mitigation of stimulated Raman scattering (SRS), which usually represents one of the limiting factors for potential applications of such systems. The spectrally broadened output up to 2 nm can be used with well-established chirped pulse amplification systems.
