For your last sentence, I’m not sure what you really mean, may be you don’t mean physical capability but more like by chance it’s unlikely. Laser can be very dangerous, especially those used in labs. I remember in my undergrad optics labs we were all told about it’s danger by telling us a story that someone setting up an array forgetting to turn off the laser (not visible spectrum so can’t tell by the color light ray as usual) and got blinded in one eye because that eye enters the optical path momentarily. And the main reason laser is so dangerous and useful is it’s coherence. That gives us those unique colors and also interference pattern when it’s shining on objects, and also the highly directional beam. That beam is almost perfectly parallel so no matter how far your target is, the intensity is still almost the same. That’s why in that article, they mention the ability to target things. If you can aim accurately, it is deadly.
