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).

A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel , missiles , vehicles, and optical devices.
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 ...
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.
Corner cube reflector Apollo 15 Lunar Laser Ranging RetroReflector (LRRR) installed on the Moon. In optics, corner reflectors typically consist of three mirrors or reflective prism faces which return an incident light beam in the opposite direction.
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 ...
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.
A fiber disk laser is a fiber laser with transverse delivery of the pump light. They are characterized by the pump beam not being parallel to the active core of the optical fiber (as in a double-clad fiber ), but directed to the coil of the fiber at an angle (usually, between 10 and 40 degrees).
