1.5 μm半导体激光的乙炔(12C2H 2)线性吸收稳频

摘要

Establishing 1.5 μm wavelength standard is the requirement of practical applications in one hand, and will fill the gap in the near infrared wavelength standard in metrology in another. The first phase of wo rk at NIM in this project is that using DFB-LDs and home made acetylene ( 12C2H2) cells, the C2H2 linaer absorption experiment and LD wavele ngt h stabilization are realized for the first time in this country. The preliminary analysis on experiment and plan for the next stage in this field are given.%建立1.5 μm波长标准的工作既是现实应用的需求，也将填 补波 长标准系列在近红外波段的空白。第一阶段工作是用国产分布反馈半导体激光(DFB-LDS)和 研制的乙炔(12C2H2)吸收室，进行了吸收光谱实验，在国内首次实现了1.5 μm BFB-LD的C2H2线性吸收稳频，并对实验结果进行初步分析和提出了下一步工作的 计划。
