Phase compensation scheme to achieve clean pulses from a multipass cell post-compression setup

An effective post-compression scheme requires a good compression system to generate the desired ultrashort pulse. In this work, we demonstrate that a compressor based on a pair of grisms, with an additional piece of dispersive glass, is able to shorten pulses coming from an all-bulk multipass cell post-compression setup to temporal profiles very close to the transform limited one. This proposal paves the way for the design of compressors, not based on chirped mirrors, with excellent performance.
