Laser‐induced energy deposition is widely discussed as a flow control technique in supersonic transportation. In case of thermal laser‐plasma upstream of a blunt body, a substantial adaptation of shock wave geometry and magnitude of wave drag is predicted. Related to the research on laser supported detonation, the paper describes the implementation of laser‐sustained plasma in a supersonic Argon jet. The stable plasma state is generated by the intersection of a Q‐switched Nd:YAG‐laser and a continuous wave CO 2 ‐laser beams, for ignition and maintenance of the plasma respectively. A miniature supersonic Ludwieg tube test facility generates a supersonic jet at velocities of Mach 2.1. Modifications of the flow and plasma conditions are investigated and characterized by Schlieren flow visualisation, laser energy transmission and plasma radiation measurements. The results include the discussions of the flow field as well as the required laser and gas parameters.
