Perovskite crystals are engineered crystals with exceptional properties. In SUPERLASER they will form the gain material in the laser – meaning the material that is used to emit light and create a laser beam. In this video, Professor Georgios Vougioukalakis discusses the unique properties of halide perovskite materials and why they are at the heart of the SUPERLASER project. With their excellent optoelectronic characteristics, tunable emission wavelengths, and solution processability, perovskites offer a powerful and sustainable platform for developing advanced light sources.
