英文摘要
Random lasers, which have properties of both a conventional laser and an illuminating light source, have not been in practical use because of their low emission efficiencies. We introduced a self-similar (fractal) structure for a random laser medium to improve the efficiency. The statistical properties of three-dimensional intensity distributions formed with fractal speckle patterns have been elucidated. An electromagnetic simulation has shown that the fractal structures are suitable for random lasing. Experiments using a photopolymer indicated that a random laser can be fabricated by illuminating a polymer medium with laser speckles.
