The first laser, invented by Theodore Maiman in May 1960. Nd:YAG laser: 1.064 μm, (1.32 μm) Flashlamp, laser diode: Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high ...
The emitters are usually lasers, making what is termed a laser dazzler. Most of the contemporary systems can be carried by a person, and operate in either the red (a laser diode) or green (a diode-pumped solid-state laser, DPSS) areas of the electromagnetic spectrum. The green laser is chosen for its unique ability to react with the human eye. [5]
Green DPSSLs are usually around 20% efficient, although some lasers can reach up to 35% efficiency. In other words, a green DPSSL using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light. In optimal conditions, Nd:YVO 4 has a conversion efficiency of 60%, [1] while KTP has a conversion efficiency of 80%. [2]
The High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS) is a Lockheed Martin-developed 300 Kilowatt high-energy laser weapon designed to intercept combat drones, fast-attack craft, and missiles. [1] After winning the contract in 2018, the first announced installation was on the USS Preble (DDG-88) in 2019. [2]
An Er:glass laser (erbium-doped glass laser) is a solid-state laser whose active laser medium is erbium-doped glass. Ytterbium (Yb) is sometimes added to these lasers to improve their efficiency. Er:glass lasers emit light in the infrared region of the electromagnetic spectrum, often in the range of 1530–1560 nanometers .

Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...
