This investigation explores, for the first time, the random laser behavior of ground powder obtained from organic-inorganic hybrid materials based on Rhodamine 6G incorporated into a di-ureasil matrix. The experimental results, both in the spectral and temporal domains, obtained by pumping with picosecond laser pulses, show the existence of efficient random laser emission in this system. Finally, the random laser performance is compared with the one of other Rhodamine-doped solid state silica compounds.
本研究首次探索了由掺入双脲硅基质的基于罗丹明6G的有机-无机杂化材料获得的研磨粉末的随机激光行为。通过皮秒激光脉冲泵浦在光谱和时间域获得的实验结果表明，该系统中存在高效的随机激光发射。最后，将该随机激光性能与其他罗丹明掺杂的固态二氧化硅化合物的性能进行了比较。
