Spectral broadening of µJ-level pulses around 8 µm in a Germanium-based multi-pass scheme
Year: 2024
Type: article
Abstract: A 2.6-fold spectral broadening of mid-infrared femtosecond µJ-level pulses has been achieved using an unfolded multi-pass configuration of germanium plates and zinc selenide lenses. This method maintains a throughput higher than 60% while preserving the spatial quality and the temporal duration of the input beam. Numerical simulations match the experimental results and show the potential to tailor the parameters of the cell to obtain different spectra.
