摘　　要：1.5μm乙炔饱和吸收谱线是国际计量委员会(CIPM)正式推荐的光纤通信波段复现‘米’定义的频率参考标准。乙炔稳频激光依据稳频方法可分为线性吸收和饱和吸收两大类,饱和吸收相比线性吸收,能够消除乙炔分子的多普勒效应,获得线宽更窄、频率稳定度和复现性更高的稳频激光,1 s频率稳定度能够达到10-13量级,波长漂移为10^(-12)量级。利用^(13)C_(2)H_(2)(ν1+ν3)P(16)谱线,研发的微型气室有望实现稳频激光的全光纤链路传播,为高度集成化、抗干扰能力强的稳频激光源提供了新的发展方向。高性能的1.5μm近红外稳频激光直接为密集波分复用系统、精密光纤传感等多个领域提供波长参考源,结合飞秒激光频率梳技术可进一步完善光纤通信中激光波长量值传递溯源体系,提升激近红外波段光波长的测量能力,为光纤波段的精密测量提供量值保障。The 1.5μm acetylene saturable absorption spectral line is the frequency reference standard officially recommended by the International Committee of Weights and Measures to reproduce the definition of‘meter’in the optical fiber communication band.Acetylene frequency stabilized laser can be divided into linear absorption and saturable absorption according to the frequency stabilization method.Compared with linear absorption,saturable absorption has the advantage of the doppler free,which makes the laser linewidth narrower,frequency stability and repeatability higher,the short-term frequency stability can reach the order of 10-13 and the wavelength drift is 10-12 magnitude.Relying on the^(13)C_(2)H_(2)(ν1+ν3)P(16)spectral line,the microcell is expected to realize the all fiber link propagation of the frequency stabilized laser,providing a new development direction for the frequency stabilized laser source with high integration and strong anti-interference ability.High performance 1.5μm near-infrared frequency stabilized laser provides wavelength reference sources for dense wavelength multiplexing systems,precision optical fiber sensing,and other fields.Combing with femtosecond optical frequency comb technology,it can further improve the laser wavelength value transmission traceability system in optical communication,improve the measurement capability of the laser wavelength in the near-infrared band,and provide a quantitative guarantee for precise measurement in the optical fiber band.
