Abstract

Since the beginning of High Energy Laser systems, simulations have been used to predict performance, do parameter trades, and assist in troubleshooting. Today, simulations benefit from higher speed computers with more memory, but they are also being asked to do more. New types of HEL devices are being proposed, more hardware details are being incorporated, beam control systems are becoming more complex, innovative new systems are being designed to work under conditions of strong turbulence, and more types of targets are being considered. There are three types of physics level codes: resonator, beam control, and lethality. All three are slow running and require a high level of expertise to use. Scaling law codes are much easier to use and much faster running. These codes are based on analytical predictions and anchored to the wave optics simulations and to experiments. Scaling law codes can quickly predict performance, weight, and volume for various scenarios and conditions. Now that HEL systems are closer to reality, there is more interest in incorporating the scaling law codes into engagement codes, which predict overall system effectiveness in battle situations.
