Properties and Applications of Random Lasers as Emerging Light Sources and Optical Sensors: A Review
Dongqin Ni, Moritz Späth, Florian Klämpfl, Martin Hohmann
Abstract
In a random laser (RL), optical feedback arises from multiple scattering instead of conventional mirrors. RLs generate a laser-like emission, and meanwhile take advantage of a simpler and more flexible laser configuration. The applicability of RLs as light sources and optical sensors has been proved. These applications have been extended to the biological field, with tissues as natural scattering materials. Herein, the current state of the RL properties and applications was reviewed.
