Few-cycle optical vortices for strong field physics
Matthieu Guer, Martin Luttmann, Jean-François Hergott +3
We report on the generation of optical vortices with few-cycle pulse durations, 500J per pulse, at a repetition rate of 1 kHz. To do so, a 25 fs laser beam at 800 nm is shaped w…
Ultrafast Hidden Spin Polarization Dynamics of Bright and Dark Excitons in 2H-WSe
Mauro Fanciulli, David Bresteau, Jérome Gaudin +9
We performed spin-, time- and angle-resolved extreme ultraviolet photoemission spectroscopy (STARPES) of excitons prepared by photoexcitation of inversion-symmetric 2H-WSe with…
Spatio-temporal pulse cleaning in multi-pass cells
Jaismeen Kaur, Louis Daniault, Zhao Cheng +5
We study both numerically and experimentally the use of two third-order nonlinear temporal filtering techniques, namely nonlinear ellipse rotation (NER) and cross-polarized wave (X…
