N2 - In this paper we report the results of experimental study of microwave (MW) discharge in the supersonic flow initiated by the laser spark and calculation of laser spark interaction with airflow. The MW discharge initiation has been produced by single and double laser sparks. By using different configuration of laser sparks in supersonic flow we demonstrate the feasibility of microwave breakdown threshold decrease and control over shape and location of MW plasma. Calculation of laser spark shock wave structures shows good agreement with experimental shadow photographs both in the front shock wave diameter and its internal structure.
