In this lecture we follow up with what we left in LAHFS (I) in the Winter Semester 2010/2011. We will first review LAHFS (I) briefly. We then emphasize special topics of choice in two or three areas through ample exercises and reports. Through these processes, we anticipate students acquire the top level of expertise in this emerging discipline.
One of the earliest suggestion to use ultraintense laser, now what is called relativistic intensities of laser, was in 1979 by Tajima and Dawson to introduce the laser acceleration. As is known through the Woodward-Lawson Theorem, mere application of laser, the transverse EM waves, is incapable of any acceleration. One needs to take advantage of what we call the relativistic nonlinearity. Laser acceleration has opened a way to the science of high fields. We dissect nonlinearities of matter based on the different level of the laser intensities, starting from the molecular nonlinearity, atomic nonlinearity, then the plasma’s relativistic nonlinearity, and finally ultra-relativistic nonlinearity. We may even have nonlinearity of vacuum beyond the horizon of matter’s nonlinearities. This is where the contemporary vacuum physics by ultra intense lasers works. Applications of high field science include: laser electron acceleration, ion acceleration, relativistic engineering, medical applications of laser acceleration, gamma ray beam physics, the next generation of high energy accelerator physics by laser, ultrafast science with intense lasers, high field science such as vacuum physics with laser, exploration of semimacro fields of unexplored regimes (such as axion-like fields and dark energy), etc. We also explain why it is necessary to go to intense fields of laser in order to reach shortest possible time scales such as in zeptoseconds and beyond through the Intense laser-Short Pulse Conjecture. Applications to astrophysics, bioscience and medicine will be also discussed. Possible projects will be suggested.
