Whereas Albert Einstein established the basics for the development of lasers, the University of Alicante shakes up the sector by creating small cheaper and excellent devices. Among other properties, the new lasers are mechanically flexible, compact, long-lasting, easy to integrate with other devices, and emit light in the visible spectrum. Its appeal lies in its potential applications and improvements in the field of optical communications and signal amplifiers; spectroscopy and medicine as light sources for treatment, for example, spots on the skin, laser hair removal and detection of chemical and biological substances.
In the latter sector, the new lasers represents a significant social advance as they detect explosive vapors present with great sensitivity, analyse food components, or different types of substances in blood-related diseases.
The key to the success of these devices is the material they are made of as it combines a new family of molecules based on oligo p-phenylenevinylenes with rigid molecular framework, called COPVs. Mainly composed of carbon and hydrogen, they have been synthesized by the group of Professor Eiichi Nakamura of the University of Tokyo, with which the research group of University of Alicante maintains a fruitful collaboration. "The application of these molecules as organic lasers is in the process of being patented", as said by María A. Díaz-García.
