  2. Nuclear pumped laser - Wikipedia

    en.wikipedia.org/wiki/Nuclear_pumped_laser

    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.

    en.wikipedia.org/wiki/Project_Excalibur

    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 ...

    en.wikipedia.org/wiki/Laser_pumping

    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]

    The 1984 SDI concept of a space based Nuclear reactor pumped laser or a chemical hydrogen fluoride laser satellite [60] resulted in this 1984 artist's concept of a laser-equipped satellite firing on another, causing a momentum change in the target object by laser ablation. Before having to cool and re-aim at further possible targets.

  9. X-ray laser - Wikipedia

    en.wikipedia.org/wiki/X-ray_laser

    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 ...
