High-Intensity and High Energy Laser Interactions with Single Droplets
Abstract
Our research accomplishments have been in five main areas: (1) Third- order sum frequency generation in the volume of the droplet and the role of phase-matching condition with droplet-cavity modes which are standing waves; (2) Retention of acoustic phonons generated by stimulated Brillouin scattering (SBS) and the role of these long-lived acoustic waves and photons in 'seeding' the SBS during the subsequent input-laser pulse; (3) Stimulated low-frequency scattering from anisotropic molecules in droplets and the effect of the low-frequency scattering process in causing the elastic scattering spectrum and the stimulated Raman scattering (SRS) spectrum to be asymmetrically broadened; (4) Resonance Raman enhancement of the SRS gain coefficient with the intent to increase the sensitivity of SRS to minor species in the droplet; and (5) The use of population inverted laser-dye molecules to provide extra gain for SRS from minor species in the droplet.
