微结构光纤波导及器件中的超快光子学效应与光子行为调控研究年度报告

摘要

Photonic crystal fiber femtosecond laser system with improved average power and pulse contrast has been studied. The photonic crystal fiber based on new material is developed. Ultra-broadband frequency tuning from visible to mid infrared has been achieved with the photonic crystal fiber laser source. Average power enhancement for THz generation has also been observed via a microstructuredGaP crystal pumped by the photonic crystal fiber laser source.%该年度主要研究了光子晶体光纤飞秒激光系统的平均功率提升与脉冲质量的改善。实现了新材料的光子晶体光纤，并利用高平均功率、高重复频率的光子晶体光纤飞秒激光系统作为泵浦源，获得了可见光-中红外的超宽带连续光谱调谐，并基于该光源泵浦具有微结构增强效应的GaP晶体，得到了THz波产生效率的显著提升。
