摘要

二维随机激光的无序增益介质结构是通过将散射介质视为确定性空腔来设计的，以实现指定的发射光谱。散射元件的棋盘式分布允许使用直接二进制搜索方法对散射体阵列进行结构优化。模拟结果表明，发射光可以集中在指定的波长段。此外，还研究了散射体尺寸和制造误差对优化发射光谱的影响。

Structural design of random lasers with specified emission bands

The structure of the disordered gain media for a two-dimensional random laser was designed to achieve the specified emission spectrum by treating the scattering medium as deterministic cavities. A checkerboard distribution of scattering elements allows structural optimization of the scatterer array using a direct binary search method. Simulation results show that the emitted light can be concentrated in the specified wavelength bands. The effects of scatterer size and fabrication errors on the optimized emission spectrum were also investigated.
