摘 要：該年度主要研究了光子晶體光纖飛秒激光系統的平均功率提升與脈沖質量的改善。實現了新材料的光子晶體光纖，并利用高平均功率、高重復頻率的光子晶體光纖飛秒激光系統作為泵浦源，獲得了可見光-中紅外的超寬帶連續光譜調諧，并基于該光源泵浦具有微結構增強效應的GaP晶體，得到了THz波產生效率的顯著提升。
關鍵詞：飛秒激光 光子晶體光纖 頻率調諧
Abstract：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.
Key Words：Femtosecond Laser；Photonic Crystal Fiber；Frequency Tunable
