Abstract
A simple Q-switched Erbium-doped fiber laser (EDFL) operating at 1556 nm is demonstrated based on a solid state saturable absorber fiber. The laser employs a newly developed Erbium-doped fiber with a high Erbium concentration as a gain medium and a 1 m long commercial Thulium-doped fiber as a Q-switcher. The EDFL generates Q-switching pulse train within 980 nm pump power tuning range from 77.2 to 97.5 mW. The repetition rate of the Q-switched pulses monotonically grows from 7.7 to 15.4 kHz while the pulse duration reduces from 21.4 to 14.1 µs as the pump power increases from 77.2 to 97.5 mW. The maximum pulse energy of 11.7 nJ is obtained at pump power of 97.5 mW.
