It seems there is a ceiling for how powerful a laser can be in a certain size. I was wondering if this is due to material costs or if it is literally impossible to have like a 50 watt laser the size of a pen. I have no doubt it comes down to power levels etc. I'll bet many of you are excited for the potential of graohene? I'd obviously not want to break any laws, but I was just wondering if there's anyone working on this. I guess when I think of a laser, all the sci-fi shows I watch come to mind. Lol. How cool would it be to have a pen sized laser that could like cut steel??
