摘要
近年来,脉冲掺镱光纤激光器技术快速发展,因其重复频率高、峰值功率高、工作在1μm重要波段以及具有光纤激光器的固有优点,在激光加工、激光医疗、光电对抗、激光目标指示和激光雷达等领域中得到广泛应用。从中近程激光测距应用角度出发,聚焦调Q技术和主振荡功率放大技术两种高重复频率长脉冲产生机制,整理了近年来高重复频率长脉冲掺镱光纤激光器的研究进展,总结了不同脉冲产生机制的掺镱光纤激光器的输出特点,并对未来脉冲掺镱光纤激光器研究重点进行了展望。
Recently,pulsed ytterbium(Yb)-doped fiber lasers have been increasingly manufactured.The high repetition rate,high peak power,significant operation wavelength,and advantages of fiber lasers,have promoted the wide use of pulsed Yb-doped fiber lasers in many fields,such as medical treatment,electro-optical countermeasures,target indication,radar,and processing.In this paper,we first review the development of high-repetition-rate long-pulse Yb-doped fiber lasers with a Q-switched mechanism and master oscillator power amplifier.Next,the output characteristics are summarized.The Q-switched mechanism can help achieve a larger pulse energy and adjust the repetition rate within a specific range,achieving a higher output power of the master oscillator compared with single-cavity all-fiber lasers,thereby meeting the demands of large-energy applications.Finally,the research trends of different pulsed Yb-doped fiber lasers are prospected for the near future.For Q-switched,the damage threshold,manufacturing difficulty,service life,and cost of the saturable absorbers must be improved.For master oscillator power amplifiers,studying and realizing more efficient gain media,simpler structures,and better stability would be a significant accomplishment.
