Laser Interactions with Single Droplets.
Abstract
Final report on past three and a quarter years of ARO support in two research areas: (1) nonlinear optical effects with single droplets, that act as high Q optical cavities; and (2) detection of bio- and nonbio-airborne particles. Research accomplishments in the first area consist of the following: (a) laser induced surface bulge; (b) mode beating among shape-distortion split resonance modes; (c) temporal asymmetry of clockwise and counter-clockwise elastic scattering; (d) model for optical bistability; (e) external versus internal pumping of stimulated Raman scattering; (f) second-harmonic generation from surfactant on hanging droplets, and (g) application of chaos theory to optical cavities. Research accomplishments of the three joint ARL-Yale experiments in bio- and nonbio-airborne particle detection are summarized. In order to optimize data capture and storage, three schemes are discussed: (1) conditional sampling; (2) conditional firing; and (3) conditional storage.
