Nike laser
Encyclopedia
The Nike laser at the United States Naval Research Laboratory
in Washington, DC is a 56 beam, 4-5 kJ per pulse electron beam pumped krypton fluoride
excimer laser
which operates in the ultraviolet at 248 nm with pulsewidths of a few nanoseconds. Nike was completed in the late 1980s and is used for investigations into inertial confinement fusion
. By using a KrF laser with induced spatial incoherence (ISI) optical smoothing, the modulations in the laser focal profile (beam intensity anisotropy) are only 1% in one beam and < 0.3% with a 44-beam overlap. This feature is especially important for minimizing the seeding of Rayleigh-Taylor instabilities in the imploding fusion target capsule plasma

Krypton fluoride laser
A krypton fluoride laser is a particular type of excimer laser, which is sometimes called an exciplex laser. With its 248 nanometer wavelength, it is a deep ultraviolet laser which is commonly used in the production of semiconductor integrated circuits, industrial micromachining, and scientific...

Inertial confinement fusion
Inertial confinement fusion is a process where nuclear fusion reactions are initiated by heating and compressing a fuel target, typically in the form of a pellet that most often contains a mixture of deuterium and tritium....

Plasma (physics)
In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. Heating a gas may ionize its molecules or atoms , thus turning it into a plasma, which contains charged particles: positive ions and negative electrons or ions...
