胆甾相液晶激光器的调谐特性研究
Tunable capability of dye-doped cholesteric liquid crystal lasers∗
摘要
Abstract
Based on the fact that helical pitch and average refractive index of a cholesteric liquid crystal is electric-tunable and temperature-tunable, we have designed dye-doped cholesteric liquid crystal (CLC) lasers. First, the effects of the concentration of chiral and the temperature on helical pitch are investigated. Next, we gain the relationship of tunable laser with temperature and electric field. When the temperature is changed from 23 to 35◦C, the wavelength shift of the lasing peak vasies from 618.90 to 594.76 nm, nearly 24.14 nm in total;when the electric field is changed from 0 to 9 V, the wavelength shift of the lasing peak ehanges from 617.40 to 608.11 nm, nearly 9.29 nm in total.关键词
