Proposal Number: ECS-9703988 Principal Investigator: Li Yan Title: Mode locking with a hybrid neodymium laser In this research, a new approach to easily and reliably generate ultrashort ( 100 fs) coherent laser pulses will be investigated. The approach involves a novel concept of mode locking with a hybrid laser, which contain both a broadband inhomogeneously broadened medium and a narrow band homogeneously broadened medium in a single cavity. As a demonstration as well as being practically useful system, a broadband Nd:phosphate glass and a narrow band Nd:YLF will be combined to form a hybrid neodymium laser. Combined theoretical and experimental investigations of this system will be pursued. The basic physics of the hybrid laser, particularly the roles of the two gain media in the dynamic mode-locking process, will be investigated. The materials science applications for ultrashort pulse lasers are growing vigorously.

提案编号：ECS-9703988 主要研究者：李岩 标题：用混合钕激光器锁模 在这项研究中，一种新的方法，容易和可靠地产生超短（100 fs）相干激光脉冲将进行调查。 该方法涉及一种新的概念，即在一个腔中同时包含宽带非均匀加宽介质和窄带均匀加宽介质的混合激光器的锁模。 作为一种示范和实用的系统，宽带Nd：磷酸盐玻璃和窄带Nd：YLF将组合成混合钕激光器。 该系统的理论和实验相结合的调查将继续进行。 混合激光器的基本物理，特别是在动态锁模过程中的两个增益介质的作用，将进行研究。 超短脉冲激光在材料科学中的应用正蓬勃发展。
