摘要：
We achieve a pulsed fiber laser based on injecting a pulsed-seed into a high power fiber ring cavity consisting of two-stage amplifier chain. Through gain control of the fiber amplifier chain and adjustment of a variable optical coupler in the cavity, locking condition is satisfied which produce mode-hopping free, single-longitudinal-mode optical spectrum with 38 dB optical signal to noise ratio. The noise-free lasing RF spectrum has a 7.0 kHz 3 dB linewidth. The nanosecond lasing pulses are jittering-free with 40 W peak power at 1550 nm wavelength. (C) 2012 Elsevier Ltd. All rights reserved.
