- Abstract
We experimentally study energy scaling properties of gas-filled multipass cell-based nonlinear compression setups by employing increasing azimuthal orders of Laguerre-Gauss LG0ℓ modes. First, we analyze the mode conversion from a Gaussian beam to LG0ℓ modes using spiral phase plates and spatial low-pass filtering. Then, these beams are sent to a first gas-filled multi-pass cell (MPC) to verify the energy scaling and spatial properties at the output. In a second experiment that allows more nonlinearity, we compare pulse compression conducted with either a Gaussian or an LG03 beam in terms of energy scaling, output temporal, spatial, spatio-spectral, and spectrally-resolved topological charge properties....

In a second experiment that allows more nonlinearity, we compare pulse compression conducted with either a Gaussian or an LG03 beam in terms of energy scaling, output temporal, spatial, spatio-spectral, and spectrally-resolved topological charge properties. The use of this structured beam allows for an increase in the input energy from 50 µJ up to 150 µJ with a final pulse duration of 60 fs, while the other parameters are essentially kept equal.
