1319nm lasers, which has extensive application prospect, play a crucial role in sodium beacons, optical communication, image display and laser medical treatment. The Nd∶YAG 1319nm lasers studies in recent years were stated briefly from the following three aspects: single-wavelength continuous output lasers, pulsed lasers and quasi-continuous-wave lasers. The important applications of 1319nm laser in multiple fields was introduced. The research value and difficulties of these lasers were also presented. Finally, the future development of Nd∶YAG 1319nm lasers were discussed.
