Abstract
The invention discloses an optical tunable laser material with high thermal stability, strong fatigue resistance, narrow half width and multistable state. The optical tunable laser material is composed of a diarylethene compound based on an endogenous chiral steric hindrance alkene bridge, a gain medium and a liquid crystal material. The mass ratio of the diarylethene compound based on the endogenous chiral steric hindrance alkene bridge to the liquid crystal material is between 1:200 and 1:18, and the mass ratio of the gain medium to the liquid crystal material is between 1:200 and 1:50; the structure of the diarylethene compound based on the endogenous chiral steric hindrance alkene bridge is shown in the specification. The light tunable laser material with high thermal stability, strong fatigue resistance, narrow half width and multistable state has the light tunable characteristics of high thermal stability, strong fatigue resistance, narrow line width, multistable state and stable spectral line shape, and meanwhile, the output laser spectrum line shape has no obvious change.
