At that point you're deliberately removing the collimation and I'm not sure how much the coherency really adds so you might as well just focus a heat lamp on them. It's still bad if it somehow does end up targeting something delicate or flammable but at least you've gone from a line to a point. Plus a 500W laser is super pricey but you can pick up a 500W heat lamp at the local hardware store. I wonder if anyone's tried it?
