摘要
激光是20世纪以来人类最重大的发明之一,当材料尺寸小至微纳尺度后,激光三要素(谐振腔、增益、泵浦方式)同传统材料相比都有很大不同。然而,无机材料可选择范围小,增益范围普遍偏窄,也不易通过晶格掺杂对材料进行改性,加之材料柔韧性差,不易加工等缺点,限制了纳米激光的应用范围。有机材料不仅在发光效率、柔性、加工性等方面表现出独特的优势,其独具特色的激发态过程使激光波长的调控成为可能。同时,有机分子之间可以通过弱相互作用,自组装成为具有不同结构的微纳晶体。这些微晶具有规整的棒状或球状,可作为法布里-珀罗或回音壁模式谐振腔。在深入认识有机π分子材料丰富的激发态过程的基础上,我们将分子材料作为增益介质,构筑真正意义的四能级系统,在进一步降低有机微纳激光出射阈值的同时,获得具有波长连续可调、波长可切换等特殊性能的微纳激光器件。
Microlasers are essential components for integrated optoelectronic devices.The abundant excited state processes in organic molecules are helpful for the design of novel laser materials and for the construction of high-performance laser devices.In addition,the unique optical properties revealed in the stimulated organic materials provide more effective means for the study of their excited state dynamics.We build the four-level energy structure via various excited state processes for the realization of microscale lasers with different functionalities.Starting from the design and synthesis of organic photofunctional molecules,we constructed microscale resonant cavities with specific structures via the controlled assembly of organic molecules,and then study their excited state processes.On this basis,we tried to figure out the relationship among the molecular structures,crystal structures,excited states,and laser performances,for the final realization of multifunctional microlasers.
