Title: Generation of Mie size microdroplet aerosols with applications in laser-driven fusion experiments

Abstract

We have developed a tunable source of Mie scale microdroplet aerosols that can be used for the generation of energetic ions. To demonstrate this potential, a terawatt Ti:Al{sub 2}O{sub 3} laser focused to 2x10{sup 19} W/cm{sup 2} was used to irradiate heavy water (D{sub 2}O) aerosols composed of micron-scale droplets. Energetic deuterium ions, which were generated in the laser-droplet interaction, produced deuterium-deuterium fusion with approximately 2x10{sup 3} fusion neutrons measured per joule of incident laser energy.
