Popis: |
This papers reports an octave-spanning coherent supercontinuum(SC) fiber laser with excellent noise and polarizationproperties. This was achieved by pumping a highly birefringent all-normal dispersion (ANDi) photonic crystal fiber with a compact high-power ytterbiumfemtosecond laser at 1049 nm. This system generates an ultra-flat SC spectrum from 670 nm to 1390 nm with a power spectral density higher than 0.4 mW/nm and apolarization extinction ratio of 17 dB across the entire bandwidth. An average pulse-to-pulse relative intensity noise (RIN) down to 0.54% from 700 nm to 1100 nmhas been measured and found to be in good agreement with numerical simulations. This highly-stable broadband source could find strong potential applications inbiomedical imaging and spectroscopy where improved signal to noise ratio is essential. |
