Photonic Associates, LLC (PALLC) is a Santa Fe high-tech company founded by Dr. Claude Phipps in 1995. We are a veteran-owned company which provides theoretical and experimental investigations of systems using laser-surface interactions - especially in the new field of laser space propulsion which we helped create. We became a partnership in 2004.
We have completed contracts for NASA, AFOSR, AFRL Edwards, DoD, MDA and Lawrence Livermore National Laboratory (LLNL), as well as several commercial entities.
You can browse Dr. Phipps' selected publications here.
Expertise: Our main experience is in laser space propulsion systems and concepts. Examples are the high-thrust and high-exhaust velocity versions of the laser plasma thruster (LPT) which have application to satellite propulsion. The LPT generates 10 millinewtons thrust at 3 millinewton/optical watt and 250 seconds specific impulse (Isp) in the millisecond-pulse model. The nanosecond model has produced 3ks Isp in tests. We have designed liquid fuel versions of this unit to generate 1 N thrust and 10ks Isp. We have expertise in linear and nonlinear optics, magneto-optics and space system design, and do in-depth technical consulting on laser applications.
International symposia: Since 1998, we have initiated and organized ten international symposia on High Power Laser Ablation in Osaka, Santa Fe and Taos.
HPLA/BEP 2014 was held at Hotel La Fonda in Santa Fe, New Mexico April 21-25, 2014. We combined forces with the International Symposium on Beamed Energy Propulsion (ISBEP). The new BEP meeting track featured microwave as well as laser sources for propulsion in space, and other phenomena beside ablation.
HPLA/DE 2016 will be held at Hotel La Fonda April 4-7. For this event, we have also combined with DEPS, the Directed Energy Professional Society. Early indications are this meeting will be the very best yet in our 18 year history! We will have 22 sessions with topics ranging from our usual talks on forefront physics to DPALS and XPALS to MAPLE, laser ablation propulsion and metamaterials. We're also honored to have 5 keynote speakers - Gérard Mourou, Aaron Lindenberg, Fabio di Teodoro, Boris Zhdanov and Mark Neice.
HPLA/DE is truly international. Over half of our 200 anticipated attendees are from institutions outside the U.S. About 150 papers will be presented.

PA analytical and numerical models:
· A widely-used analytical model for predicting pressure generation on opaque surfaces in vacuum, caused by laser pulse duration from 100ps to 1ms, across the spectrum from excimer to carbon dioxide laser wavelengths.
· Codes which calculate 1-D pressure and impulse, with a smooth transition between the vapor regime (from impulse threshold to plasma threshold) and plasma-dominated regimes
· A code which simulates ground-to-orbit flight of a cone-shaped ablation-driven vehicle through a real atmosphere with appropriate velocity- and density-dependent drag coefficients
PA inventions include the laser plasma thruster "LPT" and the laser space debris clearing concept. NASA conducted a validation study that concluded LODR (then called ORION) should be pursued.
