自从一九六○年第一个激光器诞生以后,由于它的频带很宽,容量极大,抗干扰性强,保密性能好,引起了各国通信工作者的很大兴趣.近年来,由于各种新式的光学系统和光电系统接连问世,促进了激光通信的发展.可以说,这是量子电子学的一个重大的成就,也是现代科学技术应用到通信工程中新的重大成果之一.
Since the birth of the first laser in 1960, it has attracted great interest among communication workers in various countries due to its wide frequency band, large capacity, strong anti-interference ability and good confidentiality. In recent years, The advent of new optical systems and optoelectronic systems has led to the development of laser communications, which can be said to be a major achievement of quantum electronics and one of the major new achievements in the application of modern science and technology to communications engineering.
