摘要

利用飞秒激光引入随机光纤光栅提供随机分布反馈，叠加光纤布拉格光栅选择激光波长，实现了一种线性腔三波长掺铥光纤随机激光器。在1943.62、1945.04和1946.32 nm处获得稳定的三波长随机激光输出。3db线宽小于0.1 nm，光信噪比(OSNR)高达45.6 dB。

Three-wavelength thulium-doped fiber random laser based on grating feedback technology

A linear cavity three-wavelength thulium-doped fiber random laser is demonstrated by using a femtosecond laser introduced random fiber grating to provide random distributed feedback and a superimposed-fiber Bragg grating to select lasing wavelengths. Stable three-wavelength random laser output is obtained at 1943.62, 1945.04 and 1946.32 nm. The 3-dB linewidth is less than 0.1 nm and the optical signal-to-noise ratio (OSNR) is up to 45.6 dB.
