Abstract
This study describes the laser generation of a 6G rhodamine in artificial opals representing single-crystal and heterostructure films. The spectral and angular properties of radiation and the threshold characteristics of generation are investigated. In the case where the 6G rhodamine was in a bulk opal, the so-called random laser generation was observed. In contrast to this, the laser generation caused by a distributed feedback inside the structure of the photonic bandgap was observed in photonic-crystal opal films.
