You are joking! I have seen lasers strike objects, such as the items in a cash register checkout line. You can't miss that. It is obvious. We have all seen it. If you got near it or put your hand over it, you would be burned. At those power levels, if you looked up, you would be permanently blinded.

Now explain how you could use these invisible frequencies to send enough electricity through an ordinary wire to melt ceramics and 3 mm thick steel, without melting the wire. If you can't explain how to do that, you can forget this and all other hidden electricity hypotheses. Keep it simple. Address the big questions and the obviously questions first. Then tell us about DC and other distortions. - Jed
