全光纤白光超连续谱实现563 W输出
Generation of 563 W all-fiber white-light supercontinuum source
摘要
受限于短脉冲泵浦源高峰值功率和高平均功率之间的矛盾, 以及短脉冲泵浦源芯径与光子晶体光纤芯径的较大差异, 现有的短脉冲白光超连续谱光源输出在200 W左右。基于短脉冲泵浦源工作频率和脉冲宽度的调节技术、高效的模场匹配技术等, 实现了kW级全光纤短脉冲泵浦源的稳定产生, 以及短脉冲泵浦源与光子晶体光纤纤芯之间的高效耦合, 产生了平均输出功率为563 W的高功率超连续谱光源, 为目前该领域公开报道的最高功率。
Abstract
Supercontinuum spectrum has wide applications in many fields, and it was one of the hottest research directions the past twenty years. However, limited by the mismatch of mode area between pig-tail of amplifier and the photonic crystal fiber and the balance of peak power and output power of the amplifier, the power of white-light supercontinuum is about 200 W. Based on frequency repetition and pulse duration of the amplifier and the high-efficient match of mode area, 563 W high power all-fiber white-light supercontinuum source was generated.
