The injection locking of an erbium-doped fiber ring laser(EDFRL)is studied,and a novel method to stabilize the wavelength and output power of tunable single-longitudinal-mode EDFRL with compound cavity structure is proposed and experimentally demonstrated.
The sensing distance is up to 50km and the SNR of sensing signal is 14dB. Then, a fiber ring laser source is used for replacing the broadband source, a tunable filter is used to differentiate sensing signals, the excellent SNR of 58dB is achieved along 50km optic fiber.
A simple actively mode-locked fiber ring laser is proposed and successfully demonstrated to generate dual-wavelength picosecond pulses with close wavelength spacing using one Bragg grating in standard single-mode fiber.
We describe a novel erbium-doped fiber ring laser utilizing the backward amplified spontaneous emission (ASE) power as a secondary pump source so that it can operate in L-band stably.
