由细菌视紫红质测定高斯光束的束腰位置(英文)

Determination of the Waist Position of a Gaussian Beam by Bacteriorhodopsin Film~*

介绍并测量了细菌视紫红质 (bR)的透过光强随入射光强的变化特性 ,并提出利用bR的非线性透过特性测定高斯光束的束腰位置 ,测量结果与利用已知的高斯光束参数所计算的结果相一致。

Relation between transmitted intensity of bacteriorhodopsin(bR) film and the incident intensity was tested.A new method of determining waist position of a Gaussian beam passing an optical system was proposed by the nonlinear transmission of the bR film.The measured results are in agreement with the calculated results based on the parameters of the Guassian beam.
