Abstract A review of authors’ contributions to dye-doped cholesteric liquid crystal (CLC) lasers started from the pioneer authors’ paper of 1980 in which the experimental realization of the first CLC laser is presented. Both distributed feedback (DFB) and photonics band edge lasing models are discussed for different experimental conditions. A detailed study and analysis of basic characteristics of steroidal CLC lasers with low liquid crystal optical birefringence is considered with respect to the DFB model. The manifestation of a planar texture quality and mutual orientations of directors on the substrates influencing on the lasing characteristics in steroidal CLCs have been shown and described. The reversible phototuning of the CLC laser wavelength by trans–cis transitions of photoactive components is realized. Reasons for two theoretical models׳ coexistence for the description of dye-doped CLC lasing is considered.

染料掺杂胆甾醇激光器：分布式反馈和光子带隙激光模型

摘要 对作者对染料掺杂胆甾型液晶 (CLC) 激光器的贡献的回顾始于 1980 年先驱作者的论文，其中介绍了第一台 CLC 激光器的实验实现。针对不同的实验条件讨论了分布式反馈 (DFB) 和光子带边缘激光模型。对低液晶光学双折射的甾体CLC激光器的基本特性进行了详细的研究和分析，考虑到了DFB模型。已经显示和描述了影响甾体CLC中激光特性的基板上的平面纹理质量和指向矢的相互取向的表现。通过光活性成分的反式-顺式跃迁实现了CLC激光波长的可逆光调谐。
