%X The two most notable methods for producing short laser pulses are mode-locked and Q-switched lasers. Whilemode-locked lasers generate pulses in the pico- (ps) to femtosecond (fs) range, Q-switched lasers typically producepulses at the nanosecond (ns) or 100 ps level [1]. Thus, mode-locking has been the superior technology whenultrashort pulses or high peak powers are required. On the other hand, Q-switched lasers can have great advantagesowing to their simplicity, compactness, low costs, and the large pulse energies that can be generated [2]. To bridgethe parameter gap between mode-locked and Q-switched lasers, pulse post-compression appears attractive. Onepossible method is self-phase-modulation (SPM) in optical fibers [3]. However, stimulated-Raman-scattering limitsthe possible peak powers to far below 1 kW and thus pulse energies to lower than μJ level for ns pulses [3]. AnotherSPM-based method are Multi-pass cells (MPCs), which have become a standard technology for post-compressionof mode-locked lasers [4]. However, MPCs have not yet been used to compress Q-switched laser pulses due to theirinherently low peak powers. Here, we demonstrate a new MPC type, facilitating post-compression of pulses withorder-of-magnitude lower peak power than typical bulk-MPCs [4]. We use a fused silica block as the nonlinearmedium and compress 1 mJ pulses from the nanosecond down to the picosecond regime.
