INTERACTION OF COHERENT LIGHT WITH SOLIDS AND WITH TURBULENT ATMOSPHERES.
Abstract
Considerable progress was made on the development of an improved theory and physical model of propagation in turbulent media. Topics studied include (1) the effective refractive index of random media; (2) the statistics of waves propagated in random media; (3) the dyadic Green's functions for vector waves propagated in random media; (4) and extension and generalization of earlier results on the validity of the Rytov approximation; and (5) a geometrical-diffraction theory of optical propagation in random media. As a second and distinct part of the research program, the nonlinear absorption of high intensity radiation was studied. A number of compounds with potential as Q-switch materials were investigated, and a rather complete picture of the mechanism responsible for their behavior has been developed. In addition, the photoisomerization of indigo dyes by giant pulse radiation has been investigated. This work yielded the first direct observation of a short-lived intermediate of a photoisomerization process. (Author)
