The formation of convex structures on the surface of colored samples of polymethylmethacrylate (PMMA) when they are irradiated by the second-harmonic radiation of a neodymium laser has been experimentally investigated. The dependences of the height and the diameter of the resulting convex microstructures on the energy density of the laser pulse have been investigated. The formation threshold of structures has been determined for various samples, and the optimum structuring regimes have been found. The possibility of obtaining arrays of convex structures (microlenses) and structures in the form of convex fillets has been demonstrated.
