Cojocaru, Marius Rutkauskas, Martynas Peckus, Valdas Sirutkaitis, Kestutis Staliunas, Hernán R. Míguez, Sergei G. Romanov, Lucio C. Andreani, Christian SeassalWe report and analyze experimental observation of the formation of a narrow, well collimated laser beam at optical frequency behind the woodpile photonic crystal fabricated using a femtosecond laser multi-photon polymerization technique. We show that the collimation depends on the input laser beam focusing conditions. We discuss the experimental results and give theoretical interpretation.
