Rectangular burst-mode Yb-doped fiber laser with MHz inter-repetition rate

We propose a compact all fiber Yb-doped rectangular burst-mode laser with high inter-burst repetition rate (~MHz) and high intra-burst repetition rate (~GHz). In this burst-mode fiber laser, the dissipative soliton resonance (DSR) passive mode-locked laser is employed to generate tunable rectangular burst-mode pulse while combining with active modulator (Electro-Optic Modulator, EOM). Tunable burst-mode pulse is achieved includes 5-10 ns of tunable burst duration, 0.8- 1.5 GHz of adjustable intra-burst repetition rate and tunable intra-burst duty cycle. The inter-burst repetition rate is 1.58 MHz. This system combing with such parameters can be employed to generate ultra-high repetition rate microwave signal at high frequency band.
