Abstract:

The direction, polarization and intensity of second harmonic light beams, generated in a crystal of NaClO3 were observed as a function of the angle of incidence, when the primary laser beam is incident from a denser linear fluid. When the angle of incidence theta sub i is smaller than the critical angle for total reflection critical theta omega, a reflected harmonic beam and two distinct spatially resolved transmitted harmonic beams with polarizations precessing in opposite senses are observed. When critical theta 2 omega theta sub i critical theta 2 omega the incident laser power is totally reflected, but one of the transmitted harmonic beams still exists. For theta sub i critical theta 2 omega, only the reflected harmonic beam remains. When two totally reflected laser beams are incident from opposite sides of the normal, second harmonic radiation occurs in the direction of both the inward and outward normal. The results agree quantitatively with the theory of Bloembergen and Pershan. Author
