For diffused waveguides with exponential and Gaussian index profiles effective refractive index as a function of the diffusion depth, and cut-off diffusion depth curves as a function of the waveguide surface index increment for some lower order modes have been plotted using these eigenvalue and cut-off equations, which can be used in measurement and fabrication of diffused c-cut LiNbO3 waveguides..

In this paper, an experimental set up and a method of measuring the scattering angle are introduced. The measuring method of the scattering angle is as follows. The guided light wave propagating in the waveguide is coupled out by a prism. The well known m-line can be observed. By measuring the distribution of the light intensity along the m-line, the line width which covers a region of -40 db from the peak of the curve can be read out. While converting it into an angle of slope of the light beam, the scattering angle is obtained. It has been found that the influence of the scattering on the profile of the to—line is not considerable in the region from 0 to -20 db. The segment of the curve coincides with the intensity distribution of the incident beam. On the oiiher hand, the intensity distribution of the incident beam can be considered as a Gaussian one. Thus we can take the segment from 0 to -20 db of the profile of the m-line as the intensity distribution of the incident beam and calculate its width at the -40 db region. Considering the intensity distribution of the incident beam, we redefine the scattering angle. Thus, the error of obtained result is reasonable..

The action of a normal pulsed ruby laser beam on a mercury plate has been investigated. It was predicted from qualitative consideration that its oharaot eristics of light transmission and reflection depend not only on the light energy density butalso on the internal pressure of the mercury plate. The front part of the acting laser pulse was absorbed and the transmission light corresponded to the pulse-tail. The phenomenon observed in our experiments is helpfu] to intarpret the mechanism of light transmission through a meroury plate. This paper reports experimental phenomenon observed in our work and makes an analysis to them..
