摘要 近来提出的在有正群速度色散的增益光纤中可以实现脉冲的自相似演化及传输的现象,给飞秒脉冲光纤放大器及激光器开辟了广阔的应用前景。应用脉冲自相似演化技术在光纤放大器及激光器中获得的脉冲能量比目前的水平高一、二个量级,且脉冲不会在高能量状态下分裂,脉冲经过去啁啾后可以得到飞秒超短脉冲,可以实现兆瓦量级的峰值功率。本文主要介绍了运用此技术的光纤放大器和激光器的实验研究及发展现状。 The phenomenon is put forward recently that pulse can self-similarly evolve and propagate in optical fibers with normal GVD and gain has a bright prospect for given femtoseeond fiber amplifier and lasers. The pulse energy obtained by self-similar evolution technique is one or two orders of magnitude larger than that of existing lasers. The pulse will not break at high power level, and it can be de-chirped to obtain a femtosecond pulse, from which million watts peak power has been realized. This paper introduces the current situation and progress of amplifiers and lasers using self-similar technique.
