New blue light-emitting lasers leverage low-toxicity colloidal quantum dots

Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various technologies, ranging from high-resolution displays to printers, medical imaging tools and data storage solutions. A key advantage of these lasers is that they generate coherent and intense light beams that can be leveraged to develop highly advanced optical technologies.
