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。
Ultra-short pulse laser in biomedical, laser micro-processing, defense and other fields have important applications. With the development of double-clad fiber laser technology, ultra-short pulse laser fiber amplification technology based on double-clad fiber or photonic crystal fiber (PCF) has drawn much attention because of its advantages in volume, efficiency and beam quality. It mainly reports the recent progress of picosecond and femtosecond ultrashort pulse laser fiber amplification at home and abroad, and introduces its typical application in micro-fabrication, supercontinuum generation and terahertz wave generation.
