美国乔治亚工科大学开发了通过化学反应使分子或原子处于激发态,然后发出激光的方法。此法耗电少,适用于重化工系统的高耗能工艺。在脉冲电动机的作用下,使硅或锗和臭氧反应,生成处于激发状态的亚稳态金属氧化物,再和气态铊原子接触,使其成 Georgia Institute of Technology in the United States has developed by chemical reaction molecules or atoms in an excited state, and then the method of laser emission. This method consumes less power and is suitable for high energy consumption process of heavy chemical system. Under the action of a pulse motor, silicon or germanium is reacted with ozone to generate a metastable metal oxide in an excited state, and then contacted with a gaseous thallium atom to form a
