主要特性 ：
①单色性好。激光的颜色很纯,其单色性比普通光源的光高1010倍以上。因此，激光光源是一种优良的相干光源，可广泛用于光通信。
②方向性强。激光束的发散立体角很小,为毫弧度量级,比普通光或微波的发散角小2～3数量级。
③光亮度高。激光焦点处的辐射亮度比普通光高108～1010倍。
主要参数如下：
Key Features:
① Good monochrome. The color of laser is very pure, and its monochromaticity is more than 1010 times higher than that of ordinary light source. Therefore, the laser light source is an excellent coherent light source and can be widely used in optical communications.
② Strong directivity. The divergence solid angle of the laser beam is very small, it is a milli-arc metric, which is 2 to 3 orders of magnitude smaller than that of ordinary light or microwave.
③ The brightness is high. The radiance at the focal point of the laser is 108 to 1010 times higher than that of ordinary light.
