Studies of Nonlinear Ultrasonic Phenomena.

The report contains an accumulation of results, many of which are in process of being published. Topics covered include: excitation of fractional harmonic ultrasonic waves; parametric phenomena in physics; Bragg imaging with finite amplitude ultrasonic waves; redistribution of a Gaussian ultrasonic beam reflected from a liquid-solid interface; determination of harmonic content of an ultrasonic wave from the asymmetry of the light diffraction pattern; and comparison of methods for absolute calibration of ultrasonic fields.
