Laser Red are the simplest laser pointers, as the laser diodes are easily available at their wavelengths. A laser red is no more than a simple battery operated laser diode; however, lasers play an important role in our everyday lives. The fact is; they show up in a wide range of products and technologies.
You'll find them in everything from CD players, dental drills, eye surgery, barcode scanner, measuring systems, and high-speed metal cutting machines. Tattoo removal, hair replacement, eye surgery also utilizes laser technology.
Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled "visible light". This visible light corresponds to a wavelength range of 400 - 700 nanometers (nm) and a color range of violet through red.
