DragonFire is a British laser directed-energy weapon (LDEW). It was first unveiled to the public as a technology demonstrator 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).

English: During a trial at the MOD’s Hebrides Range, the DragonFire laser directed energy weapon (LDEW) system achieved the UK’s first high-power firing of a laser weapon against aerial targets. The range of DragonFire is classified, but it is a line-of-sight weapon and can engage with any visible target.
The Gen 3 laser has a number of upgrades that provide improved beam quality, increased electrical to optical efficiency, and reduced size and weight; the assembly is small at only 1.3 by 0.4 by 0.5 metres (4.3 ft × 1.3 ft × 1.6 ft), and is powered by a compact Lithium-ion battery to demonstrate deployability on tactical platforms. Beam ...
A simple, dense smoke screen can and will often block a laser beam. Infrared or multi-spectrum [93] smoke grenades or generators will also disturb or block infrared laser beams. Any opaque case, cowling, bodywork, fuselage, hull, wall, shield or armor will absorb at least the "first impact" of a laser weapon, so the beam must be sustained to ...
However a number of other beam types have been used to trap particles, including high order laser beams i.e. Hermite-Gaussian beams (TEM xy), Laguerre-Gaussian (LG) beams (TEM pl) and Bessel beams. Optical tweezers based on Laguerre-Gaussian beams have the unique capability of trapping particles that are optically reflective and absorptive.
When the trigger is pulled, the mechanism in the toy makes sounds and causes sparks to appear inside the transparent red cone on the front. A raygun is a science-fiction directed-energy weapon usually with destructive effect. [1] They have various names: ray gun, death ray, beam gun, blaster, laser gun, laser pistol, phaser, zap gun, etc. In ...
The beam splitter divides the laser light into two paths, one of which has a phase modulator as described above. The beams are then recombined. Changing the electric field on the phase modulating path will then determine whether the two beams interfere constructively or destructively at the output, and thereby control the amplitude or intensity ...
Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation. Power levels of several watts are possible. Beam quality can be extremely high- often rivaling that of an ion laser.
