摘　　要：利用管棒法拉制出单位长度增益大于3.0dB/cm的高掺杂浓度的铒镱共掺磷酸盐单模光纤;以这种光纤作为增益介质,并利用非线性偏振旋转技术实现了毫瓦级脉冲激光输出.当泵浦功率为300mW时,环形腔光纤激光器的平均输出功率为8.13mW,脉冲重复率为17.1MHz,脉冲激光光谱的3-dB带宽为0.49nm,转换极限脉冲宽度为5.0ps.A kind of Er3＋/Yb3＋ co-doped phosphate fiber with gain per unit length greater than 3.0 dB/cm was fabricated by the rod-in-tube technique. It generated milliwatt pulse laser by using mode-locked technique of nonlinear polarization rotation （NPR）. When the pump power was 300 mW,the average output power,pulse repetition rate,transform-limited pulse duration and 3-dB spectrum width of the laser were 8.13 mW,17.1 MHz,5.0 ps and 0.49 nm respectively.
