This Letter presents a polarimetric study of the emission of random lasers from organic dyes. Coherent lasing modes from samples with ethanol solvent showed a high degree of polarization and did not influence each other in polarization. The proper choice of a laser dye with asymmetric absorption momenta, a highly viscous solvent, and a linear pump polarization can cause the random lasing emission to be completely linearly polarized for all wavelengths within the amplification range.
这封信介绍了对有机染料随机激光发射的偏振研究。具有乙醇溶剂的样品的相干激光模式表现出高度的偏振，并且在偏振方面不会相互影响。适当选择具有不对称吸收动量的激光染料、高粘性溶剂和线性泵浦偏振，可以使随机激光发射在整个放大范围内的所有波长完全线偏振。
