Recent upgrade of the CO2 laser at the Accelerator Test Facility brought its power up to the terawatt level. This power regime provides new opportunities to study high-energy-density physics and fundamental properties of matter. The CO2 laser operates at 10.6 micron and
therefore is comparable to petawatt solid state lasers for the experiments that require a large pondermotive potential. The higher repetition rate of ATF CO2 laser in comparison with it solid state analog (more then two orders of magnitude) increases its reach into low cross section processes.
Complementing the CO2 laser, the high brightness electron beam at ATF allows studies of laser-beam interactions in the extreme fields of a tightly focused laser. We will report on recent exciting results from nonlinear Compton scattering experiments as well as plans to utilize
previously unreachable accelerating gradients to produce fast electrons, neutrons and ions. We are inviting ideas on how to utilize the CO2 laser and electron beams' potential for laboratory creation and probing of energized plasmas such as found around black holes and neutron stars.
