| 中文摘要:光纤中的非线性效应是限制高功率
光纤激光器发展的重要因素。通过抑制激光器时域的不稳定性(自
脉冲现象)，可以提升非线性效应的阈值。基于全光纤化的谐振
腔引入了简单的光纤珐珀腔，使噪声抖动降至原先的1/3，并实现了自脉冲
抑制的稳定的连续激光输出。这种简单的腔结构保持了较高的
斜率效率(76.5%)，实现了高功率的激光输出(48.7 W泵浦光产
生36.5 W激光)。这种腔结构中的全光纤化谐振腔不仅可以用作稳定的
连续激光运转激光器，而且还可以用作更高功率光纤放大器的种子，用于限
制非线性效应的产生。 |

| Abstract:The nonlinear noise effect in optical
fibers is an important factor to limit the development of
high power fiber lasers. The threshold of nonlinear effect
can be improved by suppressing the time domain instability (self-pulsing
phenomenon) of lasers. On the basis of an all-fiber resonator
cavity, a simple fiber Fabry-Perot cavity is incorporated. The
noise dither is reduced to one third of its original value and
stable continuous laser output suppressed by self-pulsing is
realized. This simple cavity structure can maintain a higher
slope efficiency (76.5%) and can implement high power laser
output (48.7 W bump light can generate 36.5 W laser). The all
fiber resonator cavity in the cavity structure not only can be
used as a stable continuous laser, but also can be used as the
seed of higher power fiber amplifiers for limiting the generation
of nonlinear effect. |
