摘要：
The wave drag reduction with acting spike induced by laser-pulse energy depositions was investigated. A time-averaged drag force is measured by the force-balance system using a load cell. Its drag resolution is 15mN and response time is better than 90ms. Laser pulses are irradiated through the BK-7 side window so that they do not suffer optical interference with the shock layer. The beam is reflected against three 45 deg mirrors, and then focused with a convex lens with a focal length of 60mm set right before the BK-7 side window. It was observed that drag reduction scales with a laser-pulse repetition frequency even with the strong pulse-to-pulse interactions.
