Abstract
Medical lasers used as ophthalmic photocoagulator are briefly reviewed. The author describes some new approaches to develop a novel laser source for these applications, and then discusses future trends and some options for medical applications. At present, the domestic market of laser equipment for medical applications is smaller than that for industrial applications, which has restricted constant growth. In this paper, laser sources for photocoagulation are mainly discussed. Photocoagulators are influenced by the development of laser sources. New applications at extremely high bright orange fiber laser photocoagulators are expected from the perspective of life cycle of new products.
