nanolaser
Microscopic light source
A nanolaser is a laser with dimensions measured in nanometers—thousands of times smaller than conventional lasers.
These devices emit coherent light from structures smaller than the wavelength of light itself, enabling applications in optical computing, high-speed data transmission, and medical imaging.
Researchers developed a nanolaser that could operate at room temperature.
