摘要: 以国产掺Yb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结构的全国产大功率全光纤激光器。在注入的最大泵浦功率为75 W时，获得了52.5 W，1 080 nm激光的稳定输出，光-光效率为70%。实验结果表明，提高泵浦功率可获得更高的输出功率。Abstract: An all-fiber-configuration master oscillator power amplification(MOPA)-structured high power laser has been constructed all with China-made components. A maximum output of 52.5 W centered at 1 080 nm is achieved at the launched pump power of 75 W. The optical to optical conversion efficiency is 70%. The experimental results have demonstrated the potential to achieve higher output power with more powerful pump source.
