Tailored Laser Pulse Trains for Burst-Mode Illumination

Technology #11534

Key Points

  • Laser system for generating at a distance narrowband tunable radio-frequency (RF) emission in the MHz and GHz ranges
  • Enables more energy to be delivered to a target while reducing the requirements needed for an ultrafast laser system
  • Possible applications include LIDAR, directed energy, RF generation, as well as military defense

Abstract

The University of Central Florida invention is a novel laser that generates directed energy at a distance consisting of a narrowband tunable radio-frequency (RF) emission in the MHz and GHz ranges for military and commercial applications. This is accomplished by creating a localized transient micro-laser plasma source with a periodic pulse function. The system is additionally constructed of coaxially stacked laser pulses with known time separations, which through the Fourier transform generate a tunable narrowband RF tone and associated harmonics at target.
