Questions about aneutronic laser fusion.

[Green Xenon [Radium]]

Hi:

Is it possible to fuse hydrogen and boron using a laser that emit 400
nm wavelength light? If so, what is the minimum amount of photons-per-
second-per-square-meter required to induce the H-B fusion?

If 400 nm wavelength is too long to have the energy needed to cause
the H-B fusion, then what is the shortest-required wavelength in order
to facilitate such fusion? What is the minimum amount of photons-per-
second-per-square-meter of that wavelength necessary for that fusion?

Note that I am interested in H-B fusion and not deuterium-tritium
fusion. This is because the former is aneutronic fusion and can be
directly converted to electricity while that latter requires a steam
turbine and causes neutron pollution.

Thanks,

Radium

P.S. These may seem like homework questions but they aren't. They are
simply questions of my genuine interest.
