摘要

本文通过测量激光在光各向异性聚合物中写入的偏振全息光栅的衍射效率，研究了倍频多模Nd:YAG激光器(532 nm, 50 mW)的时间相干函数。用光栅谱仪测量了激光的功率谱。根据实测光谱计算了相干函数。在傅里叶变换中，测量的频谱被近似为具有不同振幅的3 /spl δ /-函数的线性组合。

Coherence function measurement of a multimode laser by polarization holography

In this paper, the temporal coherence function of a frequency-doubled multimode Nd:YAG laser (532 nm, 50 mW) has been investigated by measuring the diffraction efficiency of the polarization holographic gratings written by the laser in photoanisotropic polymer. The power spectrum of the laser-beam has also been measured by a grating spectrometer. From the measured spectrum the coherence function has been calculated. At the Fourier transformation measured spectrum has been approximated by a linear combination of three /spl delta/-function with different amplitudes.
