Setup to Measure Polarization-Resolved Light Scattered from Relativistic Free Electrons in an Intense Laser Focus
Free electrons, when subjected to an intense laser field, can undergo relativistic motion that gives rise to unique patterns in the scattered light. Harmonics of the laser field are radiated into various angles out the side of the laser focus. The different harmonic orders are expected to exhibit different radiation patterns. The two polarization components of a given harmonic are expected to exhibit different radiation patterns as well. We describe an apparatus designed to measure polarization-resolved fundamental, second, and third harmonic light from relativistic free electrons. The laser polarization is both manually and electronically rotatable relative to the direction of detector.
