摘要
为满足高功率激光系统末级功率提升的要求,研制了高功率光纤放大器,它采用双包层掺Yb3+光纤作为增益介质,利用泵浦合束器进行泵浦的级联放大。通过有效的热管理及输出稳定技术,对于大信号1 053 nm波长的输入光,该光纤放大器的增益大于22 dB;采用增益均衡技术,20 nm带宽范围内增益平坦度小于2 dB。
In order to meet the requirement of enhancing the output power of high power laser system in last stage, high power fiber amplifier is developed. The amplifier adopts Yb-doped double cladding fiber as the gain medium, uses pump combiner to carry out cascaded amplification of the pump. By using effective heat management and output stabilization technology the gain of the fiber amplifier achieves more than 22 dB for the large signal input light at 1 053 nm; by using gain balance technology the gain flatness is less than 2 dB within 20 nm bandwidth.
