The purpose of this program is to conduct research toward the development of a tunable coherent source based on nonlinear optical effects, to demonstrate a tunable coherent light source, and to demonstrate parametric gain at optical frequencies. Work was continued as follows 1 An experiment to produce an optical difference frequency between two gas lasers 2 development of a calibrated optical marginal oscillator for the detection and measurement of a small amount of optical parametric gain 3 development of quantitative theory for optical parametric effects and 4 development of improved technology and components for experimental work in nonlinear optics.
