最近几年,美国国防部广泛研究了高能激光器的军用可能性,以确定那些地方可最有效地使用光武器,那些地方它们的独特性能能最好发挥。这些研究表明,在光武器能很快实际应用的那些地方,如舰艇和地面部队的低空防御,它们面临常规武器在成本效率比方面的强烈竞争。在常规武器不能满足要求或非常规武器能完成任务的那些应用中(如轰炸机防御、导弹防御和宇宙飞行器防御),高能激光器面临着困难的技术要求。最近几年,国防部光武器应用研究的投 In recent years, the U.S. Department of Defense has studied extensively the military possibilities of high-energy lasers to determine where light-weapons can be most effectively used, where their unique properties are best served. These studies show that in light of the practical applications of light weapons, such as the low-altitude defense of naval and ground forces, they face strong competition for cost-effectiveness of conventional weapons. High-energy lasers face difficult technical requirements in those applications where conventional weapons can not meet the requirements or unconventional weapons can fulfill their mission, such as bomber defense, missile defense and spacecraft defense. In recent years, Defense Department of light weapons application research cast
