Sure, all you need to do is build your lasers from unobtainium so they

Please don't joke. I am asking a serious question.

Or, you could use ordinary lasers directly like the laser light show
people do.

But the fusion-induced light will be much brighter and will cause a
lot more EMI/RFI. Right?

Oh, don't forget to notify the FAA you are going to do it or you go
to jail.

Okay but what if this laser is on a football field and pointed upward
during the show?
