摘要
设计了一种非对称环形复合谐振腔,将光纤环行器、光纤可调谐滤波器和光纤环形滤波器分别嵌入到主环形腔内,基于游标效应的原理,实现了调谐范围1020~1090 nm的高效、稳定可调谐单频光纤激光器。采用980 nm半导体激光器作为泵浦源,在中心波长1064 nm处,当泵浦功率为200 mW时,利用延迟自外差法测得单频激光的输出线宽为3.325 kHz,光信噪比均大于50 dB,以5 min为间隔,40 min内测得输出激光波长稳定性为0.02 nm。
In this work, a tunable single-frequency fiber laser with asymmetric compound ring cavity is designed.Fiber ring resonator, fiber optic tunable filter, and fiber ring filter are respectively embedded into the main fiber ring cavity. An efficient and stable tunable single-frequency fiber laser from 1020 nm to 1090 nm is achieved based on the principle of the vernier effect. A 980 nm semiconductor laser is used as the pump source, when the pump power is200 mW, the output linewidth of the single-frequency laser measured by the delayed self-heterodyne method is3. 325 kHz, and the optical signal-to-noise ratio is greater than 50 dB, with 5 min as the interval, the measured output laser wavelength stability is 0. 02 nm within 40 min.
