关于环聚焦系统的应用,国外已做了大量的研究工作。如将这种新型的聚焦方法用于受控热核反应、空间通讯、军事等方面。近几年来,在国内也已开始了研究工作。如河北省科学院激光研究所,在环聚焦透镜的成象原理及应用等方面已进行了卓有成效的研究工作。尤其在应用方面,力图在工业生产上(如钟表轮轴的焊接、玻璃管的切割、打大孔、深孔及直孔等方面)得到广泛的应用。并于1981年试制出了第一块激光束环聚焦透
About the application of the ring focusing system, a great deal of research work has been done abroad. Such as the use of this new focus method for controlled thermonuclear reaction, space communications, military and so on. In recent years, research work has begun in China. Such as the Hebei Academy of Sciences Institute of laser, focusing on the ring of the imaging principle and application of the lens has carried out fruitful research work. Especially in the application, trying to be widely used in industrial production (such as the welding of clock and axle, glass tube cutting, playing big holes, deep holes and straight holes, etc.) are widely used. And in 1981 trial produced the first laser beam focusing ring
