    Can someone please explain the alleged physics of this? I can’t tell if it’s pseudoscience nonsense or genius.

    If the latter, is this exothermic? By fast-burning these isotopes, won’t you release alot of energy too? Or is the laser just that costly that it’s net negative?

      in theory at least it's okay :

      CPA produces high-intensity, super-short optical pulses that pack a tremendous amount of power (…)
      This capability is what Mourou hopes give CPA a chance of neutralizing nuclear waste, (…)

      Yet, it is not efficient :

      Rodney C. Ewing of Stanford tells Bloomberg, “I can imagine that the physics might work, but the transmutation of high-level nuclear waste requires a number of challenging steps, such as the separation of individual radionuclides, the fabrication of targets on a large scale, and finally, their irradiation and disposal.”
