Blue laser - Wikipedia
A blue laser emits electromagnetic radiation with a wavelength between 400 and 500 nanometers, which the human eye sees in the visible spectrum as blue or violet. [1] Blue lasers can be produced by: Lasers emitting wavelengths below 445 nm appear violet, but are nonetheless also called blue lasers.
The Blue Laser and Its Applications in Industry and Science
What is a Blue Laser? The blue laser is a device that emits a light beam in the wavelength range between 400 nm and 500 nm, visible as violet or blue to the human eye. The light beam produced is temporally coherent and can be well-collimated, which allows it to have numerous applications in industry and science.
