Yes, they're applying the technique to miniature electronics, I'm wondering what the physical limits are to laser acceleration of particles (protons, say). It seems like you could transfer momentum to any particle traveling slower than might speed - so you could get a relatively high momentum; and you could accelerate neutral particles ... Why would it not work? For avoidance of doubt, I'm not imagining a miniature device, just possibly a linear device that is maybe smaller than LHC. They used to use linear arrays prior to development of synchro-cyclotrons, IIRC. Seems like it would be somewhat akin to a beam of single particle light-sails. Basically, I was imagining this - https://www.sciencedaily.com/releases/2023/07/230731110723.htm https://www.sciencedaily.com/releases/2023/07/230731110723.h... "New method improves proton acceleration with high power laser". All my best ideas have already been done!
