I know the feeling piesak. I remember when I got my first laser. It was a limited 1mW 532nm. But it was enough to get me fixed. I then later increased its power through modification. It only reached <10mW, but it was enough for me to start to appreciate the safe usage of higher power lasers. Only then did I progress onto more powerful Class 3b/4's. The fact that you are interested in science is a huge positive. It tells me you don't just like them because they are cool.
