【摘要】 综述了双包层光纤激光器端面、侧面和集中抽运耦合技术,分析表明侧面抽运耦合技术比端面抽运耦合技术更有利于获得高功率输出,其中分布包层抽运耦合技术是很理想的一种侧面抽运耦合方式。阐述了高功率光纤激光器的特点并介绍了光子晶体光纤和螺旋芯光纤的抽运耦合方式。更多还原

【Abstract】 End pumping, side pumping and collective pumping methods for double-dad fiber laserare introduced. Among these methods, the side pumping has many advantages over the end pumping technology for high power output. Distributed pumping method is an ideal side pumping choice. The characteristics of high power fiber lasers are given and the pumping methods for photonic crystal fiber and helical-core fiber are introduced.更多还原
