  • Title: High power Er,Yb-doped superfluorescent fiber source with over 16 W output near 1.55 μm.
    Author: Chen W, Shen D, Zhao T, Yang X.
    Journal: Opt Express; 2012 Jun 18; 20(13):14542-6. PubMed ID: 22714515.
    Abstract:
    We report on high-power operation of a cladding-pumped Er,Yb -doped broadband superfluorescent fiber source in the 1.55 μm spectral region. Over 16 W of single-ended amplified spontaneous emission output was generated employing a simple, all-fiber geometry without the use of a high reflectivity mirror or seed source. The wavelength range spanned from ~1531 nm to 1568.5 nm with a bandwidth (FWHM) of ~17 nm and the corresponding slope efficiency with respect to launched pump power at 975 nm was 30.7%.
