摘要
当前,超强超快激光正朝着全固态、高重复频率、新波段等方向发展,而发展新型激光材料是其关键基础之一。稀土掺杂碱土氟化物激光晶体兼具有晶体的高热导和玻璃的宽光谱特性,在全固态重复频率超强超快激光领域具有重要应用。本文简要概述了萤石型氟化物晶体稀土离子团簇结构的基本特征、稀土离子局域结构的演变规律,围绕稀土掺杂碱土氟化物激光晶体的结构设计、光谱调控及激光应用,综述了局域结构设计在探索新型宽光谱超快激光材料方面的最新研究进展,并对其发展趋势进行展望。
Abstract
Presently, the superintense and ultrafast laser technologies are developed towards all-solid-state, high-repetition-rate and new wavelength bands. As one of the most important factors, the development of new laser gain materials becomes more and more crucial. Rare-earth doped alkaline-earth fluoride laser crystals have high thermal conductivities and broad spectral bandwidths, which are very promising in generation of all-solid-state high-repetition-rate ultrafast lasers. In this work, the rare-earth cluster structure characteristics and the evolving processes and features are briefly summarized. Focusing on the structural design, spectral regulation and laser applications, the framework of local structure design for exploring new broadband ultrafast rare-earth doped alkaline-earth fluoride laser crystals is reviewed, along with the recent advances. The development trends were also prospected.
