摘要:

利用一台室温工作的垂直外腔面发射激光器,在1550 nm附近进行了时间分辨傅里叶变换干涉法的腔内激光吸收光谱分析。在等效光程为15 km时,半导体盘激光器的高分辨光谱同时覆盖了17 nm。对于65 km的最长路径长度,报告了一秒平均等于1.5 × 10^{-10} cm^{-1}.Hz^{-1/2}/光谱元素的噪声等效吸收系数。

英文摘要:

A room temperature operating Vertical External Cavity Surface Emitting Laser is applied around 1550 nm to intracavity laser absorption spectroscopy analyzed by time-resolved Fourier transform interferometry. At an equivalent pathlength of 15 km, the high resolution spectrum of the semiconductor disk laser emission covers 17 nm simultaneously. A noise equivalent absorption coefficient at one second averaging equal to 1.5 10^{-10} cm^{-1}.Hz^{-1/2} per spectral element is reported for the 65 km longest path length employed.
