有机晶体由于具有长程有序性和高化学纯度等特点，在固体激光器中的应用引起了人们的极大兴趣。作为光学增益材料，它们表现出类似于非晶对应物的高受激发射截面和宽可调谐波长发射;此外，高纯度和高有序度赋予它们优异的上级性质，例如低散射陷阱密度、高热稳定性以及高偏振发射。作为电子材料，它们有可能支持高电流密度，从而使实现电流驱动激光器成为可能。本文主要介绍有机半导体激光晶体的研究进展。介绍了晶体激光器件的构建分子、晶体生长方法及其与晶体结构相关的受激发射特性，并对晶体激光器件的研究现状进行了综述。此外，在纳米晶体激光器和单晶发光晶体管（LETs）的最新进展。最后对激光晶体的发展及其应用作了展望和个人的看法。
Because of long-range order and high chemical purity, organic crystals have exhibit unique properties and attracted a lot of interest for application in solid-state lasers. As optical gain materials, they exhibit high stimulated emission cross section and broad tunable wavelength emission as similar to their amorphous counterpart; moreover, high purity and high order give them superior properties such as low scattering trap densities, high thermal stability, as well as highly polarized emission. As electronic materials, they are potentially able to support high current densities, thus making it possible to realize current driven lasers. This paper mainly describes recent research progress in organic semiconductor laser crystals. The building molecules, crystal growth methods, as well as their stimulated emission characteristics related with crystal structures are introduced; in addition, the current state-of-the-art in the field of crystal laser devices is reviewed. Furthermore, recent advances of crystal lasers at the nanoscale and single crystal light-emitting transistors (LETs) are presented. Finally, an outlook and personal view is provided on the further developments of laser crystals and their applications.
