自聚焦激光器光学镜片对通信用激光器来说是一种价高而又笨重的装置，但是由于它们能将发射的激光聚焦而去进行传输话音和数据之类的有用工作，所以镜片又是相当重要的附件。目前，已经制造出一种称之为晶体环带激光器或叫Ｚ一激光器的实验型装置的原型，装置采用了全新的... Self-focusing lasers Optical lenses are a high-priced but cumbersome device for communication lasers, but they are also important because they focus the emitted laser light on useful tasks such as transmitting voice and data Accessories. At present, a prototype of an experimental device called a crystal ring laser or a Z-laser has been manufactured with a new ...
