TL;DR: In this article, the reflected second-harmonic intensity generated by an incident beam which is totally reflected by the nonlinear medium immersed in a denser linear medium is observed. And the role of momentum matching for the reflected intensity is demonstrated.
Abstract: We have observed the reflected second-harmonic intensity generated by an incident beam which is totally reflected by the nonlinear medium immersed in a denser linear medium. The reflected intensity becomes very high near the critical angle for total reflection. The role of momentum matching for the reflected intensity is demonstrated.

TL;DR: In this article, the intensity of polarized light reflected from an absorbing vapour has been calculated for optical radio-frequency double resonance and level-crossing, using the equations of classical electromagnetism.
Abstract: The intensity of polarized light reflected from an absorbing vapour has been calculated for optical radio-frequency double resonance and level-crossing. The reflection coefficient was obtained from the refractive index of the vapour, using the equations of classical electromagnetism. The result obtained by integration over a range of frequencies corresponding to broad-band illumination shows that all the familiar magnetic resonance effects are to be expected in the reflected light, except that the resonance curves should be Doppler- and pressure-broadened. A study of the zero-field level-crossing curve, as a function of vapour pressure, should enable one to follow the gradual transition from diffuse to coherent scattering, and to test whether the simple theory of selective reflection is adequate.

Abstract: The trajectory of the energy of a beam of light is the ray; in anisotropic media the direction of the ray is not, in general, normal to the wave front. Angles of incidence, of reflection, and of refraction are the angles which the respective wave normals make with the normal to the surface. Even in anisotropic media the wave normals, which are the directions of beams of light, obey the coplanar law of reflection and refraction.The limiting direction of a ray in any medium is the boundary surface of the medium. Hence the direction of a beam is not necessarily limited by the boundary surface of the medium. Thus in anisotropic media it is possible to have angles of incidence, of reflection, and of refraction greater than 90° even though light (i.e. energy) still remains inside the medium. Such angles of incidence, of reflection, and of refraction up to 94° have been observed with a cleaved rhomb of calcite. The theoretical calculations and experimental results are reported in this paper.
