The invention is suitable for adjusting the position of the lens in the laser fusion target room.

Description

technical field [0001] The invention relates to the field of three-degree-of-freedom precision adjustment devices for optical lenses. Background technique [0002] The limited reserves of non-renewable energy represented by fossil fuels cannot sustain the long-term development of mankind. Nuclear fusion has the advantages of less environmental pollution, sufficient fuel, and large energy release, and is expected to achieve sustainable energy supply. As one of the methods of controlled nuclear fusion, inertial confinement laser fusion has been highly valued by the scientific and technological circles in recent years. [0003] To produce the ultra-high temperature and ultra-high pressure conditions required for fusion, multiple high-energy lasers must be precisely focused on the target sphere in the target chamber. Therefore, the precise adjustment of the spatial position of the focusing lens is one of the key technologies for inertial confinement laser fusion. However, it ...
