In this paper, we proceed with design and construction of a quasi-random laser with coherent feedback made of a metallic photonic crystal slab as a cavity and Rhodamine 6G solution as a gain medium. The photonic crystal slab consists of the triangular gold nano beads arranged in a hexagonal lattice using nano-sphere lithography. Spectral emission intensity as well as the spectral width as a function of pumping energy were measured experimentally. Moreover, the physics behind the functional behavior of the structure is investigated through finite-element method. The results show that there is a considerable amount of scattering across the ordered structure which is important in the laser performance.
