Abstract: We demonstrate passive coherent combining in multipass cells using free-space delay lines for spectral broadening and pulse compression. By dividing temporarily the initial pulse into two replicas, the pulses of 250-μJ energy and 1-ps pulse duration were compressed to 272-fs. The setup offers excellent passive stability, enabling efficient high-energy pulse compression.
