Low-intensity-noise wavelength-tunable picosecond Yb fiber laser

We demonstrate a polarization-maintaining mode-locked Yb fiber laser generating low-noise picosecond pulses with a wavelength tunability from 1020.5 to 1038.8 nm. Wavelength-tuning was performed by physically compressing the intracavity chirped fiber Bragg grating for dispersion compensation and filtering. Within the tunability of 18.3 nm, the relative intensity noise is smaller than -159.2 dB Hz(-1) at a frequency of 32 MHz.

Automated summary

We have demonstrated a polarization-maintaining mode-locked Yb fiber laser that generates low-noise picosecond pulses with wavelength tunability. The relative intensity noise is very low within the tunable range.
