Chirped pulse amplified dissipative-soliton Erbium-doped fiber lasers

Abstract

An all-fiber amplification and compression system seed is demonstrated by using a chirped pulse oscillator at the telecommunication band. Dispersion management is applied successfully both in the oscillator and amplifier, allowing dissipative soliton (DS) generation and amplification. The oscillator generates 4-ps chirped pulses with 130 mW (4.55 nJ) average power. Benefiting from large chirp and the high energy of DSs from the oscillator, the amplification system can be simplified. The average power after amplification is increased to 324.2 mW, corresponding to a single pulse energy of 11.3 nJ. The minimum pulse duration is 190 fs after the single-mode fiber (SMF) is employed to compress the pulses. The repetition rate of pulses is 28.6 MHz.
