Abstract.

In this paper, we report on the realization of a 20-fs, 20-mJ laser chain operating at a repetition rate of one kilohertz. We emphasise the control on the pulse temporal and spatial profile, and its amplification at high average powers. This 1-kHz, terawatt laser is well suited for applications in high-field physics when low-intensity signal averaging is needed.
