| 摘 要： | A new type of high-power broadband superfluorescent source of Yb^3＋ -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.

| 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.
