【Abstract】 Target and beam alignment unit is one of the core parts of high power laser drivers and plays a crucial role in the adjustment of target position and pose, the laser pointing and so on. Combined the alignment accuracy requirements of the laser driver with the physics experiment implement, basic functions of the target and beam alignment unit can be acquired to meet the requirements of physics experiments using the design and adjustment of the optical-mechanical-electronic systems. However, with the increasing number of the main lasers, slewing of multi-beams and positioning with high accuracy have become the goal of developing target and beam alignment unit. Present studies on the target and beam alignment unit of both domestic and international high power laser drivers are reviewed, a universal method for the alignment unit design is investigated and main issues in the development of the target and beam alignment unit are also analyzed.更多还原
