A single-frequency Q-switched erbium-doped fiber ring laser is implemented for producing a single frequency with 25-Mhz laser linewidth, Q-switched pulses with a high peak power at 1557.5 mm. The single longitudinal mode is selected by a distributed Bragg reflector fiber laser, and a fiberoptic Mach-Zehnder interferometer acts as a Q-switch. The peak power and the average power of the Q-switched pulses vary with the repetition rate.
实现了一种单频调Q掺铒光纤环形激光器，用于产生线宽为25MHz的单频、在1557.5nm处具有高峰值功率的调Q脉冲。通过分布式布拉格反射器光纤激光器选择单纵模，光纤马赫-曾德尔干涉仪用作Q开关。调Q脉冲的峰值功率和平均功率随重复率而变化。
