| Summary: | This paper describes the setup and experimental results for an entirely centred erbium-doped
fiber laser with passively mode-locked output. The gain medium of the ring laser cavity
configuration comprises a 3m length of two-core optical fiber, wherein an undoped outer
core region of 9.38 μm diameter surrounds a 4.00 μm diameter central core region doped with
erbium ions at 400 ppm concentration. The generated stable soliton mode-locking output has a
central wavelength of 1533 nm and pulses that yield an average output power of 0.33mW with
a pulse energy of 31.8 pJ. The pulse duration is 0.7 ps and the measured output repetition rate
of 10.37MHz corresponds to a 96.4 ns pulse spacing in the pulse train. |
