Abstract

Possible designs of high power fiber lasers are discussed in this paper related to the future power delivery system in laser material processing factories. The performance of high power fiber lasers is analyzed using basic equations and optical parameters of laser cavities. High efficiency operation of 73% was demonstrated by clad pumping scheme using homogeneous absorption regime of Nd³⁺-doped rectangular double clad fibers. The possibility of solar pumping without any concentrator was evaluated using power scaling law of pumping to lasing. Fiber embedded lasing disk and tube are proposed for the high power laser which produces more than 1 kW from a single core of 50 micro-meter in diameter.
