摘要

制备具有外部谐振腔的胆甾相液晶激光器件。采用镀有多层膜的ITO玻璃作为基板

取向后制备1D-PC/CLC/1D-PC 结构的胆甾相液晶激光器件。该激光器件在532 nm的Nd :YAG倍频脉冲激光器泵浦下能够出射双模激光。出射激光峰位分别位于600 nm 和650 nm

对应于胆甾相液晶的短波边缘和长波边缘

并且激光的发射阈值明显低于普通的盒式胆甾相液晶激光器件。此激光器件可以通过电压控制在单模发射和多模发射之间切换

电控的阈值电压仅为6 V。

Abstract

This work reports the CLC laser based on the combination of dye-doped CLC and a PC consisting of SiO

and TiO

multilayers

with the structure as 1D-PC/dye-doped CLC/1D-PC. The device exhibits two-mode laser action. The wavelength lasers are at 600 nm and 650 nm

corresponding to the short-and long-wavelength band edges respectively. In this system

the lasing threshold is much lower than that in simple CLC cell without the PC. Additio-nally

two-mode laser can be switched to single-mode laser by applying above 6 V voltage.
