...“The calculation results show enhancements of fusion yields by orders of magnitude with currently available intense low-frequency laser fields,” highlighted the study.

For a collision energy of 1 keV—a level where fusion is normally almost impossible—the application of a 1.55 eV low-frequency laser can transform the reaction rate.

At 10^20 W/cm² intensity, the fusion probability increases by three orders of magnitude, while increasing the intensity to 5×10^21 W/cm² boosts the efficiency by a staggering nine orders of magnitude.

This dramatic increase effectively makes fusion at 1 keV (relatively low temperature) as probable as fusion at 10 keV without laser assistance...
