激光在通信技术领域的应用目前主要体现在两个方面:一个是无线激光通信即空间激光通信;另一个是有线激光通信即光纤通信。无线激光通信是把激光束作为通信的载波在空间传输信息的一种通信方式;有线激光通信虽然也是将激光束作为通信的载波,但它是在光纤内传输信息的一种通信方式。可见,两者的区别只在于前者是激光束在空间传输信息的无线传输,而后者则是在光纤内传输信息的有线传输。早期无线
The application of laser in the field of communication technology is mainly reflected in two aspects: one is wireless laser communication that is space laser communication; the other is wired laser communication that is optical fiber communication. Wireless laser communication is a kind of communication mode in which laser beam is used as a communication carrier to transmit information in space. Although wired laser communication uses laser beam as a carrier for communication, it is a communication method for transmitting information in optical fiber. Visible, the only difference between the two is that the former is the laser beam wireless transmission of information in the space, while the latter is in the fiber optic transmission of information within the wired transmission. Early wireless
