Sub-2-cycle post-compression of multi-mJ energy Ti:sapphire laser pulses in a gas-filled multi-pass cell

Research output: Contribution to journalArticlepeer-review

Abstract

We report on the nonlinear temporal post-compression of 7 mJ sub-40 fs pulses from a commercial kHz Ti:sapphire laser down to a record 3.8 fs duration (sub-1.5 optical cycle) in a compact single-stage gas-filled multi-pass cell (MPC), with 60% overall compression efficiency.
