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 ...
In late 2018, IPG acquired Genesis Systems, a robotic integration company. [4] IPG announced the release of the LightWELD 1500, a handheld laser welding system, late in 2020. [28] In 2021, Valentin Gapontsev stepped down as chief executive officer, retaining a position as Executive Chairman of the company. Then, Eugene Scherbakov succeeded Dr ...
The systems interleaved unique player identification codes within the weapon code bits transmitted by the laser, which were then stored by the receiver system of any player that was hit. [4] Those systems utilized a controller gun to initialize each player, thus preventing players from "resurrecting" themselves by re-inserting the yellow weapon ...
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 ...
Semiconductors, a type of solid, crystal with uniform dopant distribution or material with differing dopant levels in which the movement of electrons can cause laser action. Semiconductor lasers are typically very small, and can be pumped with a simple electric current, enabling them to be used in consumer devices such as compact disc players.
These were the Electra and Nike laser systems. Because the excimer laser is a gas-based system, the laser does not heat up like solid-state systems such as National Ignition Facility and the Omega Laser. Electra demonstrated 90,000 shots in 10 hours; ideal for a Inertial fusion power plant. [33]

An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
