【摘要】 建立 1 5 μm波长标准的工作既是现实应用的需求 ,也将填补波长计量标准系列在近红外波段的空白。本文报导中国计量科学研究院在这项研究中的第一阶段工作 :用国产分布反馈半导体激光 (DFB LD)和自行研制的乙炔 (1 2 C2 H2 )吸收室 ,进行了吸收光谱实验 ,实现了 1 5 μmBFB LD的C2 H2 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设想更多还原

【Abstract】 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 work is reported at NIM in this project: using DFB LDs and home made acetylene ( 12 C 2H 2) cells, the authors have realized the C 2H 2 linear absorption experiment and LD wavelength stabilization for the first time in this country. Preliminary analysis on our experiment and plan for the next stage of our work are also given in the paper.更多还原
