High-quality pulse compression using a hybrid all-bulk multipass cell scheme
[EN]We present a detailed numerical study of ultrashort pulse compression using a three-stage hybrid all-bulk multipass cell scheme. By operating in the enhanced frequency chirp regime, we achieve the compression of pulses from around 180 fs to 4 fs pulse duration (a total compression factor above 4...

| Resumo: | [EN]We present a detailed numerical study of ultrashort pulse compression using a three-stage hybrid all-bulk multipass cell scheme. By operating in the enhanced frequency chirp regime, we achieve the compression of pulses from around 180 fs to 4 fs pulse duration (a total compression factor above 45), with side lobes contributing with intensity values lower than 0.3 % of the peak intensity. Optimal conditions for the enhanced frequency chirp regime propagation have been identified, enabling smooth spectral broadening and high-quality temporal profiles. The first two stages are based on bulk multipass cells to achieve a controlled spectral broadening, while the third stage consists of a thin plate to reach the spectral broadening needed for few cycle pulses without leaving the enhanced frequency chirp regime. |
