The dependence of intensity and position of laser diffraction from capillary waves on incident angles was studied by means of diffraction.When the laser beam obliquely impinges on capillary waves at the different incident angles,the diffraction intensity and position change with the incident angles,and there is a phenomenon of missing orders in the diffraction patterns.Asymmetry of diffraction positions increases with the increase of the incident angle.The theory of laser diffraction from capillary waves at the different incident angles was found,and the analytic expression of the diffraction intensity and position at the different incident angles was obtained.The theoretical and experimental results are in good agreement.The conclusion is valuable for the theory and the application of laser diffraction from capillary waves.
