一、前言激光(Laser)具有如下的特性: 1)单色性(发射光的频谱宽度极窄) 2)相干性(空间的和时间的相干性好) 3)方向性(光线的发散角小) 4)亮度大(能量密度高) 与其说这是几个独立性质,不如说这几个特性之间有密切的关系。而且,这些特性还正在不断提高。关于激光在医学方面的应用,除当前用在眼科和外科的治疗装置与生化检验以外,真正的应用还可以说正处于研究之中。有关
I. Introduction Laser has the following characteristics: 1) Monochromaticity (the spectral width of the emitted light is extremely narrow) 2) Coherence (spatial and temporal coherence is good) 3) Directionality (the light divergence angle is small ) 4) Brightness (high energy density) This is not so much a few independent properties as having a close relationship between these properties. Moreover, these features are also constantly improving. With regard to the application of lasers in medicine, in addition to the current therapeutic devices and biochemical tests used in ophthalmology and surgery, the real applications can be said to be under study. related
