Mode-locked L-band bismuth–erbium fiber laser using carbon nanotubes
A passively mode-locked, bismuth–erbium-codoped fiber (Bi-EDF) with a pulse width of 460 fs is proposed and demonstrated. A highly doped, 180-cm Bi-EDF with an erbium concentration of 3,250 ppm/wt and an absorption rate of 133 dB/m at 1,530 nm serves as the gain medium. The cavity is 11.6 m long...

Summary: | A passively mode-locked, bismuth–erbium-codoped fiber (Bi-EDF) with a pulse width of 460 fs is proposed and demonstrated. A highly doped, 180-cm Bi-EDF
with an erbium concentration of 3,250 ppm/wt and an
absorption rate of 133 dB/m at 1,530 nm serves as the gain
medium. The cavity is 11.6 m long with an overall group
velocity dispersion of ?0.063 ps2
. The output pulses have
a repetition rate, average output power, pulse energy and
peak power of 11.18 MHz, 5 mW, 448 pJ and 1 kW,
respectively. The system has a high beam quality and a
narrow pulse width output in the L-band region. |
