Abstract:

This thesis developed a propagation model that can be used to investigate the performance of coherent and incoherent beam configurations subjected to diffraction and thermal blooming effects. The propagation model also provides an additional damage assessment parameterpower-in-the-bucketas well as the irradiance in the target plane for any laser wavelength. The propagation model results have target irradiance patterns similar to those obtained from Wave Train, although the peak irradiance differs by 30 due to differences in thermal blooming modeling. In addition, the propagation model can optimize certain beamlet configurations peak irradiance using a genetic algorithm. Based on all the simulation results, a 13-beamlet configuration is deemed to have highest peak irradiance and power-in-the-bucket than all the tested multiple beam configurations.
