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. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a ...
Another military use of lasers is as a laser target designator. This is a low-power laser pointer used to indicate a target for a precision-guided munition, typically launched from an aircraft. The guided munition adjusts its flight-path to home in to the laser light reflected by the target, enabling a great precision in aiming.
The carbon-dioxide laser ( CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output ...

The ELI Beamlines Facility located in Dolní Břežany, Czech Republic. The Extreme Light Infrastructure ( ELI ERIC) is a research organization with the world's largest collection of high power-lasers. [1] ELI operates several high-power, high-repetition-rate laser systems which enable the research of physical, chemical, materials, and medical ...
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 copper vapor laser ( CVL) uses vapors of copper as the lasing medium in a 4-level laser. [1] It produces green laser light at 510.6 nm and yellow laser light at 578.2 nm. The pulse width is typically from 5 to 60 ns, and peak power from 50 to 5000 kW. Its pulse repetition frequencies can be 2 to 100 kHz.
Lasers, amplifiers and laser systems for materials processing, communications, entertainment, medical, biotechnology, scientific and advance applications. IPG Photonics Corporation is an American manufacturer of fiber lasers. [2] IPG Photonics developed and commercialized optical fiber lasers, [3] which are used in a variety of applications ...
