Autor: 王挺峰 Wang Ting-feng, 郭劲 Guo Jin, 刘海波 Liu Hai-bo, 张合勇 Zhang Heyong, 赵帅 Zhao Shuai

Publikováno v: Optics and Precision Engineering. 20:2132-2139

On the basis of the properties of two beams in heterodyne detection,the photon statistical models for the coherent light and multi-mode thermal light fields were analyzed.The second and third order statistical characters of the two kinds of optical f

Autor: 刘洪波 Liu Hong-bo, 赵帅 Zhao Shuai, 郭劲 Guo Jin, 刘立生 Liu Li-Sheng, 张合勇 Zhang Heyong

Publikováno v: Optics and Precision Engineering. 19:2366-2372

A heterodyne detection experiment is established to measure the constant rotation velocity and the variable velocity of targets,in which the diffuse reflectance target and simple harmonic motion model are taken as research targets.For uniform rotatio

Evaluation of far field optical quality of TEA CO2laser with unstable resonator

Autor: 王挺峰 Wang Ting-feng, 张合勇 Zhang Heyong, 郭汝海 Guo Ru-hai

Publikováno v: Optics and Precision Engineering. 19:407-413

The evaluation methods for far field optical quality of a TEA CO2 laser with a unstable resonator were researched. Based on the real data of the unstable resonator modified by the stable resonator of a high power TEA CO2 laser,three common theoretica
