We hereby present an ongoing experiment where high power, sub-picosecond 10 µm laser pulses will be produced at 1 Hz. To achieve this 3 ps pulses of a 2 GW CO2 laser were broadened via self-phase modulation in GaAs and compressed in a dispersive element. Temporal and spectral data are presented which demonstrate the possibility of compression by more than a factor of 3.
