| Abstract: | 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. |
