国产全光纤结构激光器实现245 W高功率激光输出
China-made 245 W fiber laser in all-fiber format
摘要
以国产掺镱光纤为增益介质，利用国产泵浦源和光纤器件，构建了主振荡功率放大(MOPA)结构的全国产大功率全光纤激光器。激光器包括10 W种子激光器和高功率放大器两部分。在注入最大泵浦功率为356 W时，获得了245 W波长1 080 nm激光的稳定输出，光-光效率为69%。激光器单次连续出光时间约30 min，功率稳定性在1%以内。目前激光器输出功率受限于泵浦功率，增加泵浦源的数目有望进一步提高输出功率。
Abstract
An all-fiber configuration master oscillator power amplification(MOPA) structured high power laser with China-made components is constructed. The fiber laser is composed of a 10 W seed laser and a high power fiber amplifier. A maximum output of 245 W centered at 1 080 nm is achieved at the launched pump power of 356 W. The optical to optical conversion efficiency is 69%. The power fluctuation is less than 1% within half an hour. The experimental results have demonstrated the potential for higher output power with more powerful pump source.
