摘　　要： 随着高功率超快光纤激光器的迅速发展,时分复制脉冲放大技术近年来获得了广泛的关注。时分复制脉冲放大技术可以通过双折射晶体组或自由空间时延来实现。将时分复制脉冲技放大技术与啁啾脉冲放大、空间分束和光子晶体光纤放大等技术相结合,运用于相干光束合成和非线性压缩,可以提升超快光纤激光器的脉冲能量和峰值功率。文中对时分复制脉冲放大技术在超快光纤激光器中的最新研究进展进行了详细综述,重点分析了时分复制脉冲放大技术在相干光束合成应用中的不同系统结构,并对时分复制脉冲放大技术的优化和发展方向进行了展望。 With the rapid development of high power ultrafast fiber lasers, divided-pulse amplification （DPA） technology has attracted extensive concerns. DPA can be implemented through birefringent crystals or freespace delay lines. By combining with the techniques of chirped pulse amplification, spatial beam splitting and photonic crystal fiber amplification, DPA can be applied to coherent beam combining and nonlinear compression in order to increase both the pulse energy and peak power of ultrafast fiber lasers. The research progress of DPA in ultrafast fiber lasers was reviewed. Different system structures of DPA in the applications of coherent beam combining were analyzed. The optimization and further development of DPA was also prospected.
