Lasing from dye-doped icosahedral quasicrystals in dichromate gelatin emulsions

We report observation of optically pumped multi-directional lasing at visible wavelengths from dye-doped three-dimensional icosahedral quasicrystals fabricated in dichromate gelatin emulsions using a novel seven-beam optical interference holographic method. The lasing pattern exhibits icosahedral symmetry.
