Abstract:
The mélange of light localization and laser emission is particularly fascinating due to the specific features of each distinctive source, accompanied by exclusive emission properties of the localized modes. Herein it is demonstrated the process of light amplification and also random laser effects from special dye-doped confined micrometric systems. We physically characterize the particular sample configurations for low and high power pumping conditions from spectral point of view. Analysis of far field spatial emission confirms that light localization and random lasing occurs in our systems upon exceeding a certain input energy threshold. In addition, the presented small-size optical systems are also highly robust and prone for immediate exploitation in the micro technological arena.
