摘　　要：空间碎片严重威胁在轨运行航天器的安全,并且对有限的轨道资源造成严重浪费。利用皮秒激光探测是高精度空间碎片激光测距的发展趋势。但是单脉冲运转的皮秒激光器峰值功率较高,易损坏光学器件,其能量与功率进一步提升难度较大。当皮秒激光以脉冲串方式运转时,可将脉冲能量分散到每个脉冲上时,不仅可以降低各单脉冲能量、避免器件损坏,也使得进一步提高皮秒激光输出功率成为可能。因此,脉冲串皮秒激光器对空间碎片的探测起到了重要推动作用,近几年得到了广泛关注。对脉冲串产生方法及激光进行概述,为从事超快皮秒激光研究人员及超快皮秒激光的应用提供技术参考。The existence of space debris seriously threatens the safety of spacecraft in orbit and causes a serious waste of limited orbital resources.Picosecond laser detection is the development trend of high-precision space debris laser ranging.However,the high peak power of a picosecond laser in single-pulse operation can easily damage optical devices,and it is difficult to further improve its energy and power.When operating in pulse burst mode,the high energy is dispersed to each pulse,which not only reduces the energy of every single pulse and avoids device damage,but also makes it possible to further improve the output power.Therefore,the pulse burst picosecond laser has played an important role in the detection of space debris,and has attracted extensive attention in recent years.Pulse bursts generation method and laser are summarized,which provides technical references for researchers engaged in ultrafast picosecond laser and the application of ultrafast picosecond laser.
