- Blue_laser abstract "A blue laser is a laser that emits electromagnetic radiation at a wavelength of between 360 and 480 nanometres, which the human eye sees as blue or violet. Blue beams are produced by gas lasers using Helium-Cadmium at 441.6 nm, and Argon-ion at 458 and 488 nm. Semiconductor laser diode lasers with blue beams are typically based on gallium(III) nitride (GaN; violet color) or indium gallium nitride (often true blue in color, but also able to produce other colors). Both blue and violet lasers can also be constructed using frequency-doubling of infrared laser wavelengths from diode lasers or diode-pumped lasers. Diode lasers which emit light at 445 nm are becoming popular as handheld lasers. Lasers emitting wavelengths below 445 nm appear violet to the human eye, a distinctly different color. This is true, for example, of the most commercially common "blue" lasers, the diode lasers used in Blu-ray applications, which emit 405 nm violet light, which is a short enough wavelength to cause fluorescence in some chemicals, in the same way as radiation further into the ultraviolet ("black light") does. Light of a shorter wavelength than 400 nm is classified as ultraviolet.Devices that employ blue laser light have applications in many areas ranging from optoelectronic data storage at high density to medical applications.".
