Abstract

Thermal effects of critical passive and active kilowatt-splices in all fiber master-oscillator power amplifier (MOPA) are investigated. Proper designs for cooling apparatus are proposed and demonstrated experimentally, for the purpose of minimizing splice heating which is critical for the reliability of high power operation. By using these optimized methods, we have demonstrated numerically and experimentally for standard 125 µm, 200 µm and 400 µm Yb fibers temperature rise of critical active splice < 0,1 K/W.
