Blue lasers can also be fabricated directly with InGaN semiconductors, which produce blue light without frequency-doubling.650nm Lasers ・ 532 nm Green Laser ・ 635nm Lasers ・ 655nm Lasers ・ 670nm Lasers・ 405nm Lasers ・ 450nm Lasers ・ 650nm Lasers ・ 445nm Lasers,the wavelength (532 nm) is near peak sensitivity of the dark-adapted eye and may appear to be 35 times brighter than a red laser of identical power output. 650nm Laser pointers use a deep red laser diode near the 650 nm(nanometers) wavelength. 405nm Laser close to ultraviolet, bordering on the very extreme of human vision, and can cause bright blue fluorescence, and thus a blue rather than violet spot.
