摘要

以罗丹明6G掺杂薄膜为增益介质，研究了六方氮化硼掺杂和不掺六方氮化硼的随机激光特性。在hBN层上引入氮化铝纳米柱作为散射体。含有hBN的样品的阈值较低，为1.38 mJ/cm2。当不存在hBN时，阈值明显升高。结果表明，利用hBN作为超薄柔性衬底用于随机激光应用的潜力。

Hexagonal Boron Nitride as a Flexible Random Laser

Random lasing properties were investigated with and without hexagonal boron nitride using rhodamine 6G doped film as the gain medium. Aluminum nitride nanocolumns as scatterers were introduced on top of the hBN layer. A lower threshold of 1.38 mJ/cm2 was achieved in samples containing hBN. Significantly higher threshold was observed when no hBN was present. Results suggest the potential of utilising hBN as an ultrathin flexible substrate for random lasing applications.
