Paper Abstract

In this paper we present the development of laser fibers and connectors in four steps. First is the development of a new coupling method of the laser and fiber. This includes the specially designed connectors which suppress temperature rise of the fibers. Second, we discuss the difference in the power transmission between a step index fiber and a graded index fiber. Third, we discuss the development of a new material for fiber coating which drastically eliminates the chance of heat break of the fiber. Finally we discuss the development of a special high power connector. The connector which has a mechanical fiber clamping structure can withstand 2 kw energy transmission and allows for easy connection of fibers and long distance laser beam transmission using a 200 m-long fiber.
