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75w时,获得了52.5W,1080nm激光的稳定输出,光一光效率为70%。实验结果表明,提高泵浦功率可获得更高的输出功率。
An all fiber configuration master oscillator power amplification (MOPA) structured constructed all with China made components. A maximum output of 52. 5 W centered at 1 080 nm pump power of 75 W. The optical to optical conversion efficiency is 70%. The experimental results have demonstrated the poten tial to achieve higher output power with more powerful pump source.
