To meet the needs, a novel low-noise fiber laser with compound cavity structure is designed. The stable single-mode operation is realized by using a transient self-written fiber grating, produced by the effect of saturable absorption within a section of unpumped erbium-doped fiber, as narrow band filter for mode selecting and linewidth squeezing. Through optical path modification, the spectral signal-to-noise ratio is better than 62 dB.

激光器采用复合腔结构,以掺铒光纤作为工作物质,通过在未被抽运的掺铒光纤中形成的瞬态自写入光纤光栅的窄带滤波特性进行选模和压窄线宽,产生稳定的单频激光输出;经过光路改进,激光输出光谱信噪比优于62 dB;利用光电负反馈电路,弛豫振荡峰下降了约25 dB,低频段强度噪声也大为改善,有效地抑制了光源的强度噪声。
