Abstract:
A wide-range and phase-locked Michelson interferometer technique is described.This technique combined with femtosecond laser is used to measure the spectrum of the rare-earth ion Nd:YVO4, which presents very high signal to noise ratio of interferometric intensity output and higher spectral resolution than traditional grating spectrophotometer.

摘要:
介绍了一种大行程相位锁定迈克尔逊干涉仪技术的实现与特性,采用飞秒激光为光源与此技术结合对稀土离子光谱进行了测量,实现了大行程的相位锁定高信噪比干涉图的采样,其傅立叶光谱分辨率明显优于利用岛津uv-3101pc分光光度计得到的吸收光谱,而且包含更加丰富的能级演化信息.
