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. Blue lasers can be produced by: direct, inorganic diode semiconductor lasers based on quantum wells of gallium(III) nitride at 380-417nm or indium gallium nitride at 450 nm
It is designed to hit drones every 2–3 seconds with 62 individual blue-violet lasers forming a combined output of 300 Kw, its engagement range is 1 to 25 km, up to a altitude of 10 km. However to reduce thermal signature it is powered entirely by batteries with no onboard power generation giving a maximum engagement duration of 2 hours. [84]
In mid-to-late 2011, 405 nm blue-violet laser diode modules with an optical power of 250 mW, based on GaN violet laser diodes made for Blu-ray disc readers, had reached the market from Chinese sources for prices of about US$60 including delivery.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
DragonFire is a British laser directed-energy weapon (LDEW) technology demonstrator.It was first unveiled to the public in 2017 at the Defence and Security Equipment International (DSEI) conference in London and is being developed by UK DragonFire, a collaboration consisting of MBDA UK, Leonardo UK, QinetiQ and the Defence Science and Technology Laboratory (Dstl).
