激光是一种相干性好、方向性强、亮度高、单色性好的受激发射光波。它的波谱范围已实现了从紫外光到红外光,到毫米波范围的各种波谱。它的应用十分广泛,在军事上的应用已有数十种。在导弹武器中的应用也十分有前途。激光制导技术发展异常迅速,激光问世仅20年,激光制导的导弹已有20余型(含正在研制的),见表(一)。一九六一年,美国陆军就提出了激光半主动制导的原理。六五年研制成功激光制导炸弹,六八年用于越南战场。六十年代中、后期,激光在导弹武器系统中的其 Laser is a good coherence, directional, high brightness, good monochromatic stimulated emission waves. Its spectral range has been achieved from UV to infrared light, to millimeter wave range of various spectrum. Its wide range of applications, dozens of military applications. The application of missile weapons is also very promising. Laser guidance technology is developing very rapidly, the laser was only 20 years, laser-guided missiles have more than 20 types (including being developed), see table (a). In 1961, the United States Army proposed the principle of semi-active laser guidance. Sixty-five successful development of laser-guided bombs, six or eight years for the Vietnam battlefield. The mid-to-late 1960s, the laser in the missile weapon system
