We demonstrate optically pumped laser medium with emission in the visible spectral range from binary solutions of Rhodamine 6G and Rhodamine B in epoxy resin as matrix without appending additional scattering centers. A frequency doubled Q-switched Nd: YAG laser was used for pumping. The generation’s behavior is similar to random laser (RL) with no external optical resonator. The influence of the nanostructured morphology of the medium on the laser properties was investigated by means of SEM, AFM, TEM, SAED, Spectrofluorimetry and Spectrometry. The laser emission is characterized by high intensity – energy per pulse – 300 µJ, threshold pump energy 1.7 mJ, relatively low beam divergence of 70 mrad (for RL) and spectrally narrowed major peak at 597 nm. The new gain medium was also investigated in a conventional tunable resonator. Generation with continuous tuning in the spectral range 590–610 nm was obtained. This new effective nanostructured medium, which shows with high optical and energy parameters, can be used in speckle-free laser imaging, time-resolved microscopy, high speed optical converters and others photonics applications.

我们展示了光泵浦激光介质，该溶液在可见光谱范围内从若丹明6G和若丹明B在环氧树脂中的二元溶液作为基质的发射而没有附加散射中心。倍频调Q的Nd：YAG激光器用于泵浦。这一代的行为类似于没有外部光学谐振器的随机激光器（RL）。通过SEM，AFM，TEM，SAED，荧光分光光度法和光谱法研究了介质的纳米结构形态对激光性能的影响。激光发射具有以下特点：高强度-每脉冲能量-300 µJ，阈值泵浦能量1.7 mJ，相对较低的70 rad的光束发散度（对于RL）和光谱窄的597 nm主峰。在传统的可调谐振器中还研究了新的增益介质。获得了在590-610 nm光谱范围内连续调谐的信号。这种新型的有效纳米结构介质具有很高的光学和能量参数，可用于无斑点激光成像，时间分辨显微镜，高速光学转换器和其他光子学应用。
