研制了一种利用激光加速弹丸的装置--"激光驱动管内加速器"。它的特点是加速管中的弹丸，并从与弹丸运动相反的方向提供激光束。激光束入射到弹体头部，在弹体头部和弹体罩内壁分别反射，然后在弹体罩内壁聚焦。使用标称输出能量为5 J/脉冲的CO2横向激发大气激光器测量操作性能。以大气为工质，获得了73 N/MW的耦合系数。
A device of accelerating a projectile using laser power, “laser-driven in-tube accelerator,” has been developed. It is characterized by accelerating the projectile in a tube and by supplying the laser beam from the direction opposite to the projectile motion. The laser beam is incident on the nose of the projectile, reflected first on the nose and second on the inner wall of the projectile shroud, then focused behind. Operation performance is measured using a CO2 transversely excited atmospheric laser of a nominal output energy of 5 J/pulse. A coupling coefficient of 73 N/MW is obtained using the atmospheric air as the working fluid.
