Photonic Products is now supplying Sanyo's latest range of high-power blue-violet lasers. The range includes three new 405-nm laser diodes, which offer 20 mW, 45 mW or 85 mW optical output power.

blue lasers became commercially available in 2001. Blue diode lasers allow for smaller pits to be used in optical discs (CD-ROMs use 780 nm pits; DVDs are 630 nm). Blue light-emitting diodes (LEDs ...

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 ...

The realization of a blue LED with the luminous efficiency higher than that of conventional ones and a bluish-purple laser diode was achieved by making crystals grow toward the direction in which the ...
