Because of its outstanding characteristics, laser has been rapidly applied to industry, agriculture, precision measurement and detection, communication and information processing, medical treatment, military and other aspects, and has caused revolutionary breakthroughs in many fields. For example, people can use the concentrated and extremely high energy of laser to process various materials and drill 200 holes in a needle; As a means to stimulate, mutate, cauterize and vaporize organisms, laser has achieved good results in practical applications of medicine and agriculture. In the field of communication, a light-guiding cable that uses a laser column to transmit signals can carry information equivalent to that carried by 20 thousand telephone copper wires; Laser is not only used in communication, night vision, early warning and ranging, but also various laser weapons and laser-guided weapons have been put into practical use.
In the future, with the further development of laser technology, the performance of laser will be further improved and the cost will be further reduced, but its application scope will continue to expand and it will play an increasingly huge role.
