Abstract

Since the first demonstration [1], nonlinear pulse compression using Herriott-type multipass cells has been widely adopted by the ultrafast laser community. In contrast to waveguides, the separation of nonlinear and dispersive elements allows extensive control over the net dispersion making it particularly interesting to investigate different nonlinear effects [2]. Recently, a factor-30 compression was shown using a hybrid multipass multi-plate setup [3]. This work relies on spectral broadening and pulse compression in a single gas-filled multipass cell. The corresponding spectral bandwidth increase can be a tremendous advantage for applications such as multimodal microscopy, broadband infrared generation and pump-probe spectroscopy..
