Paper Abstract

The fundamental mechanism of the optical power loss of Gaussian light beam in dielectric corner reflector is examined i.e. diffractional scattering on the edge of corner reflector. Estimated value of relative losses is obtained for both polarizations of light beam with Goos-Haenchen shift taken into account. For the wave polarized parallel to the edge of corner reflector for the incident angle α =π/4 the estimated value is (Wdifr/W0)H is approximately equal to 3.82(λ0/a), and for transverse polarization is (Wdifr/W0)E is approximately equal to 7.03(λ0/a). Here λ0 is the optical wavelength in vacuum and a is the effective beam radius.
