六十年代初发明的激光是一种新型的光源,它具有光谱纯、发射角小、能量密度高、相干性好等特点,是综合了量子力学、电子学、光学、辐射学、结晶学等学科的先进成就而产生的一项尖端技术,它的出现无论在理论上和实用中都具有划时代的意义,十年来发展很快。把激光引进眼科领域主要有以下意义:(1)它的光能可作治疗工具;(2)各个领域
The laser invented in the early 1960s is a new type of light source. It has the characteristics of pure spectrum, small emission angle, high energy density and good coherence. It is a combination of quantum mechanics, electronics, optics, radiology and crystallography The emergence of a cutting-edge technology resulting from the advanced achievements of the discipline has its epoch-making significance both in theory and in practice. It has developed rapidly in the past decade. The introduction of the laser in the field of ophthalmology mainly has the following significance: (1) its light energy can be used as a treatment tool; (2) various fields
