Kaunas University of Technology (KTU), Lithuania researchers and scientists from Japan have developed a unique nanolaser. Although the dimensions of this laser are so small that its structure can only be seen through a powerful microscope, its potential is vast. With applications in early medical diagnostics, data communication, and security technologies, this invention could also become a key tool for the study of light and matter interactions.
Depending on the application, lasers differ in the way light is amplified and produced, which determines the colour of the radiation and the quality of the laser beam.
"Nanolasers are lasers that use structures a million times smaller than a millimetre to generate and amplify light, and the laser radiation is generated in an extremely tiny volume of material," says Dr Mindaugas Juodėnas, one of the authors of the invention.
