A nuclear pumped laser is laser pumped with the energy of fission fragments. The lasing medium is enclosed in a tube lined with uranium-235 and subjected to high neutron flux in a nuclear reactor core. The fission fragments of the uranium create excited plasma with inverse population of energy levels, which then lases.
Nuclear explosion pumped X-ray lasers require validation of many of the physical concepts before their application to strategic defense can be evaluated. [ 77 ] The report also noted that the energy requirements for a directed energy weapon used as a BMD asset was much higher than the energy needed for the same weapon to be used against those ...
Nuclear fission is used in exotic nuclear pumped lasers (NPL), directly employing the energy of the fast neutrons released in a nuclear reactor. [42] [43] The United States military tested an X-ray laser pumped by a nuclear weapon in the 1980s, but the results of the test were inconclusive and it has not been repeated. [44] [45]
GE Hitachi Nuclear Energy's Global Laser Enrichment Receives Nuclear Regulatory Commission License for Uranium Plant First-of-a-Kind Facility Licensed by NRC to Make Laser Enrichment of Uranium a ...
As the common visible-light laser transitions between electronic or vibrational states correspond to energies up to only about 10 eV, different active media are needed for X-ray lasers. Between 1978 and 1988 in Project Excalibur the U.S. military attempted to develop a nuclear explosion-pumped X-ray laser for ballistic missile defense as part ...
Ion laser Spectroscopy Optically pumped semiconductor laser 920 nm-1.35 μm Laser diode Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation.
Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion. The technique was developed by the 1966 Nobel Prize winner Alfred Kastler in the ...
