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…
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…
Conservation of a Half-Integer Angular Momentum in Nonlinear Optics with a Polarization Möbius Strip
Martin Luttmann, Mekha Vimal, Matthieu Guer +5
Symmetries and conservation laws of energy, linear momentum and angular momentum play a central role in physics, in particular in nonlinear optics. Recently, light fields with non…
Single-stage few-cycle nonlinear compression of milliJoule energy Ti:Sa femtosecond pulses in a multipass cell
Louis Daniault, Zhao Cheng, Jaismeen Kaur +7
We report on the nonlinear temporal compression of mJ energy pulses from a Ti:Sa chirped pulse amplifier system in a multipass cell filled with argon. The pulses are compressed fro…
