ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to borrow the term for Paul McManamon) a Phased Array of Phased Arrays (PAPA) geometry wherein large(r) subapertures are compensated using an Intra-Subaperture Adaptive Optical (ISAO) system within each subaperture, reducing the number of subapertures that must be phased for the full array [Nutronics, Inc. Conformal Laser Weapon System Phase I Final Report 21 March 2011]. This approach in turn imposes a requirement to compensate for atmospheric aberrations within a subaperture. Our team (comprised of Nutronics, Inc., UCLA, and Optical Physics Company) propose to investigate the trade space of options for ISAO systems and develop a conceptual design for a demonstrator to be developed during a potential follow-on Phase 2 effort. The trade space will include conventional options that utilize a small DM in the subaperture as well as off-loading ISAO wavefront sensor outputs to in-line electro-optic modulators in the outgoing beam path. BENEFIT: The proposed effort has numerous potential benefits and commercial applications, including (but not limited to): laser communication, space situational awareness, astronomical ground based imaging, laser radar, laser rangefinding, aircraft self defense (both commercial and military), air-base defense, ship self-defense, and tactical precision strike.
