英文摘要	In this paper, we investigate the bichromatic coherent random lasing actions from the dye-doped polymer stabilized blue phase liquid crystals. Two groups of lasing peaks, of which the full widith at half maximum is about 0.3 nm, are clearly observed. The shorter-and longer-wavelength modes are associated with the excitation of the single laser dye (DCM) monomers and dimers respectively. The experimental results show that the competition between the two groups of the lasing peaks can be controlled by varying the polarization of the pump light. When the polarization of the pump light is rotated from 0 degrees to 90 degrees, the intensity of the shorter-wavelength lasing peak group reduces while the intensity of the longer-wavelength lasing peak group increases. In addition, a red shift of the longer-wavelength modes is also observed and the physical mechanisms behind the red-shift phenomenon are discussed.; National Natural Science Foundation of China [11474021, 51333001]; Key Program for International S&T Cooperation Projects of China [2013DFB50340]; Issues of Priority Development Areas of the Research Fund for the Doctoral Program of Higher Education of China [20120001130005]; Key (Key Grant) Project of Chinese Ministry of Education [313002]; SCI(E); EI; 中国科技核心期刊(ISTIC); ARTICLE; luogen@bit.edu.cn; yanghuai@pku.edu.cn; 9; 103-108; 25
