Sub-80-fs pulses from an all-fiber-integrated dissipative-soliton laser at 1 µm.
We report on a passively mode-locked femtosecond fiber oscillator using only fiber-based components without intracavity dispersion compensation. The all-normal dispersion fiber laser operates in the dissipative-soliton regime and utilizes a spectral filter for pulse shaping. The 3.8 ps long pulses with pulse energies of 3.6 nJ can be dechirped with a grating compressor to 76 fs. The output spectrum reveals a full width at half maximum of 39.7 nm and a center wavelength of 1032 nm. The repetition rate is 71 MHz. The influence of pulse energy variation is discussed.
