Noncollinear Optical Gating

Date Mo, 13.01.2014 - Mo, 13.01.2014
Time 16:45
Speaker Christoph Heyl, Lund University, Sweden
Location ETH Zurich, Hönggerberg Campus, HPF G-6
Program The generation of isolated attosecond pulses via high-order harmonic generation (HHG), a key issue in attosecond science, requires intense few-cycle laser pulses and advanced gating techniques. Commonly used gating schemes rely on manipulating the fundamental driving field in order to confine the extreme ultraviolet emission to a single half cycle. Here, a different approach is presented, based on driving HHG in a noncollinear geometry. Noncollinear frequency mixing techniques are commonly employed for low-order frequency conversion processes but have not attracted much attention in attosecond science. In this talk, general aspects of noncollinear high-order wave mixing processes are discussed, focusing on the generation of isolated attosecond pulses. The noncollinear geometry can be used to angularly streak the generated attosecond pulse train, allowing access to multiple isolated attosecond pulses. Our approach constitutes the first gating scheme which allows a direct angular separation of the generated exe ultraviolet radiation from the fundamental field and does not require any manipulation of the driving field. It is therefore ideally suited for pump-probe studies in the extreme ultraviolet regime and promises new advances for intra-cavity high-order harmonic generation.
