Hi:

Is it physically-possible to design and build a 400 nm laser that is
directly-"pumped" by aneutronic nuclear fusion and in which the active
lasing medium/gain-medium is a rare-earth crystal?

The "pump" is the part of the laser that excites the atoms in the laser
medium.

Hydrogen-Boron fusion is an example of aneutronic fusion. 400 nm is
about the shortest wavelength the human eye can detect.

In aneutronic fusion no more than 1% of the total energy released is
carried by neutrons. Aneutronic fusion is the best nuclear power.


Thanks,

Aneutronic fusion
From Wikipedia, the free encyclopedia
Jump to: navigation, search

Aneutronic fusion is any form of fusion power where no more than 1% of the total energy released is carried by neutrons.[citation needed] Since the most-studied fusion reactions release up to 80% of their energy in neutrons, successful aneutronic fusion would greatly reduce problems associated with neutron radiation such as ionizing damage, neutron activation, and requirements for biological shielding, remote handling, and safety issues. Some proponents also see a potential for dramatic cost reductions by converting the energy of the charged fusion products directly to electricity. The conditions required to harness aneutronic fusion are much more extreme than those required for the conventional deuterium–tritium (DT) fuel cycle. Even if sustained aneutronic fusion is one day shown to be scientifically feasible, it is still speculative whether power production could be made economical.
