摘　　要：声光调Q光纤激光器具有所需驱动调制电压很低,容易实现对连续激光调Q获得高重复频率脉冲输出的特点。介绍了声光调Q光纤激光器的原理,并对影响它性能的几个重要因素如自发辐射的放大、泵浦功率和速率、光纤的选择、声光Q开关的重复频率等主要因素做理论分析,提出了优化这些因素的方法。The AOM Q-switched fiber laser is modulated by low voltage, so it can abtain high-power pulse with high repetition by Q- switching continous-wave. The principle of AOM Q- switched fiber laser was introduced. The key factors which affect its performances were theoretically analyzed, such as amplification of spontaneous emission, the power and rate of pump, the choices of fibers, the repetition rate of acousto-optic modulator and so on. The methods that can optimize these factors were given.
