在目前尖端技术中,将光子集中得到极高能量密度的激光器占有特殊地位。由于它在医疗器械应用方面的成功,引起军方对它的兴趣。最近的进展主要集中在激光武器方面,如英国皇家海军所装备的激光武器系统即反应出这方面取得的进展。目前用在电子战(干扰)、导弹末制导(目标照射)以及测距方面的激光器,均属低能量激光器。激光器与雷达(光学雷达)组成地形跟踪设备,可越过障碍为战机和主战坦克搜索和捕获目标。自1963年半导体激光器(砷化镓-Nd-YaG)问世以来,已成为许多军事演习和仿真设备不可缺少的设备。
In the current state-of-the-art, lasers that concentrate photons at extremely high energy dens have a special place. The military’s interest in it is due to its success in medical device applications. Recent developments have focused mainly on laser weapons, as reflected in the progress made by the Royal Navy’s laser weapon system. Currently used in electronic warfare (interference), missile guidance (target illumination) and distance measurement of the laser, are low-energy laser. Lasers and radars (optical radars) make up the terrain-tracking device that can be used to search and capture targets for fighters and MBTs across obstacles. Since the advent of semiconductor lasers (gallium arsenide-Nd-YaG) in 1963, it has become an indispensable device for many military exercises and simulation equipment.
