Theoretical and experimental investigation of aerodynamic window for high-power laser

Abstract

A new type of aerodynamic window structure using jet- injection is developed. The theoretical analysis and experimental research are presented as well. Results showed that while the lowest sealing pressure is 5.0 Torr and gas consumption is 35 g/s, the ratio of the Strehl reaches 0.98. The new aerodynamic window is demonstrated satisfactorily in the experiment connected to high-power laser.
