高平均功率超短脉冲激光光纤放大研究进展

The Research Development of Fiber-Based High Average Power Ultrashort Pulse Amplification

超短脉冲激光在生物医学、激光微加工、国防等领域有重要的应用。随着双包层光纤激光技术的发展,基于双包层光纤或光子晶体光纤(PCF)的超短脉冲激光光纤放大技术由于在体积、效率、光束质量等方面的优势,倍受关注。主要报道国内外皮秒和飞秒级超短脉冲激光光纤放大的最新进展,介绍其在微加工、超连续谱产生和太赫兹波产生方面的典型应用。

Ultrashort pulse has important applications in many fileds.such as biological medicine,laser micro processing,national defense.With the development of double clad fiber laser,the fiber amplication of ultrashort pulse based on double clad fiber or photonic crystal fiber（PCF）is paid close attention for the advantages in size,efficiency,beam quality and so on .The fatest progress of the amplification of picosecond and femtosecond ultrashort pulse at home and abroad was reported,and the typical application in the micro-processing, the supercontinuum and terahertz radiation generation was introduced.
