| Abstract: | 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. |

| Keywords: | waist position Gaussian beam bacteriorhodopsin(bR) |
