Abstract

Here we report the laser actions inside an active organic–inorganic grating with some irregular perturbation. In an optical excitation experiment, band-edge and random-laser emissions were both observed. The laser thresholds of the two laser actions are very close, which shows that random laser sometimes can operate with a threshold comparable to band-edge emission. Owing to the diffraction of the grating, directional emission with a narrow divergence angle was also obtained.
