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: direct, inorganic diode semiconductor lasers based on quantum wells of gallium (III) nitride at 380-417nm [2] [3] or indium gallium nitride at 450 ...
Laser pointer. Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Shuji Nakamura (中村 修二, Nakamura Shūji, born May 22, 1954) is a Japanese-American electronic engineer and inventor of the blue LED, a major breakthrough in lighting technology. [5] Nakamura specializes in the field of semiconductor technology, and he is a professor of materials science at the College of Engineering of the University of ...
A mosquito laser is a proposed device that would use lasers to kill mosquitoes. The primary goal would be to reduce malaria infection rates. In 2007, the Bill & Melinda Gates Foundation asked Intellectual Ventures to find a way to fight and eventually end malaria. [1] There, astrophysicist Lowell Wood had the idea to use lasers. [1]
