激光是一种受激跃迁辐射,它具有能量高度集中、方向性强、单色性好等特点。其激光器有好多种,如氮分子、氦——氖、二氧化碳、钕玻璃、红宝石等等,按其形态区分有气体、固体和液体激光器。激光是六十年代初期兴起的一门新的科学技术,目前已广泛应用在各个方面。在农业上它正作为一个新的诱变因素进入育种工作领域。目前我国已有近二十个省、市、自治区开展了这项工作,并已选育 Laser is a stimulated transition radiation, it has a high degree of energy concentration, directional, monochromatic and so good. There are many kinds of lasers, such as nitrogen molecules, helium-neon, carbon dioxide, neodymium glass, ruby ​​and so on, according to their morphology distinguish between gas, solid and liquid lasers. Laser is a new science and technology emerging in the early 1960s, and has been widely used in various fields at present. In agriculture, it is entering the field of breeding as a new mutating factor. At present, nearly 20 provinces, cities and autonomous regions in our country have carried out this work and have selected them
