LOVE LASERS, they are so cool! and i didn't know there are so many different kinds of them.

Recently i 3d printed parts for my Steemit related laser project, and hope to post the results within a few days.

Once i read a story about Theodore H. Maiman the maker and there was no practical use for his invention at that moment in time, and it was only after he died that the technology really took of, now we do so many things with lasers.

Sad story, great invention.
