To many of us a laser is merely a beam of light, but apparently that is not so as this interesting little video shows. Of course, we should have realised that there is more to a laser than just light, otherwise there would be lasers everywhere and as we know, there are no lasers worth speaking about!
This video explains why lasers are not used in the same way as we see in science fiction films and TV shows. I always thought that when we reached the 21st century, everything would be futuristic, but apparently, we still have a long way to go.
