Question: Can you put a laser though a brick?

Matthew Selwood answered on 7 Mar 2019:

It depends on what you mean; if you want to transmit the laser and use it on the other side of the wall, not really? It is far more likely to drill a hole in the wall than it is to pass through! That is why my camera turns the laser into x-rays first, which can pass through a wall rather easily 🙂
