Kaluza MC, Schlenvoigt HP, Mangles SPD, et al., 2011, Optical characterization of laser-driven electron acceleration
We present the first well-resolved experimental observation of the non-linear formation of a laser-driven plasma wave, its breaking leading to self-injection and acceleration of electrons in the wave's electric field in the regime of "Bubble-acceleration". FIO/ LS Technical Digest © 2011 OSA.

Recent theoretical and experimental studies point to better efficiency of laser-driven ion acceleration when approaching the critical plasma density regime. Simultaneously, this is the condition for observing solitons: "bubble"-like quasi-stationary plasma formations with laser radiation trapped inside. Exploring this regime with ultra-intense solid state lasers is problematic due to the lack of plasma sources and imaging methods at ∼1021 cm-3 electron density. The terawatt picosecond CO2 laser operated at Brookhaven's Accelerator Test Facility offers a solution to this problem. At the 10 μm laser wavelength, the critical plasma density is 1019 cm-3, which is attainable with gas jets and can be optically probed with visible light. Capitalizing on this approach, we focused a circular-polarized CO2 laser beam with α0=0.5 onto a hydrogen gas jet and observed monoenergetic proton beams in the 1 MeV range. Simultaneously, the laser/plasma interaction region has been optically probed with a 2nd harmonic picosecond Nd:YAG laser to reveal hole boring and stationary soliton-like plasma formations. 2D PIC simulations agree with experimental results and aid in their interpretation.
