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: Al2 O3 laser focused to 2×10 19 W/cm2 was used to irradiate heavy water (D2 O) aerosols composed of micron-scale droplets. Energetic deuterium ions, which were generated in the laser-droplet interaction, produced deuterium-deuterium fusion with approximately 2×10^3 fusion neutrons measured per joule of incident laser energy.
