Abstract: |
A new type of high-power broadband superfluorescent source of Yb3+-doped double-cladding photonic crystal fiber is reported experimentally, which is pumped at 976 nm by a high-power laser
diode with the end-coupling method. We have obtained a smooth broadband output of superfluorescence. The maximum output power
is 1.649 W with a slope efficiency of 56.7%. The 3 dB bandwidth is 22.4 nm. To the best of our knowledge, this is the first
report about SFS with such high output power of 1.649 W.
