We demonstrate nonlinear temporal compression of a high energy Yb-doped fiber laser source in a multipass cell filled with argon. The $160\ \mu \text{J}\ 275$ fs input pulses are compressed down to $135\ \mu \text{J}\ 33$ fs at the output, corresponding to an overall transmission of 85%. We also analyze the output beam, revealing essentially no space-time couplings. We believe this technique can be scalable to higher pulse energies and shorter pulse durations, enabling access to a wider parameter range for a large variety of ultrafast laser sources.
