TW-class sub-2-cycle post-compression of Ti:Sapphire laser pulses in a gas-filled multipass cell

Louis Daniault, Jaismeen Kaur, Geoffrey Gallé +3

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 4 fs duration (1.5 optical cycle) in a compac…
