Homebuilt Ruby Laser

I made some significant improvements to my ruby laser: now it burns holes through steel razor blades and makes a plume of fire when striking targets containing a high percentage of carbon. The beam is visible, although it is at the edge of the visible spectrum and therefore does not appear particularly bright to the eye. It also does not scatter as noticeably from dust and smoke as do visible lasers with shorter wavelengths (like green or blue).

More detail with much clearer pictures can be found on my Flickr site at:

You've done something I've dreamed of doing since I was a kid - Build a high power ruby laser. Do you have any detailed plans or photos? Where did you get the crystal? I must know more.

@shkunk1

I have a web site (under construction). I'll post my web site address on my Youtube channel.

Well this project is definitely worth of attention, not like those clown 200 mW green laser crap! Well done bro!

@Binarychicken

Well, thanks. However, those greenies are still dangerous. You've only got 2 eyes, and if you're blind, you're blind. The handhelds are more dangerous in a sense: they can be pointed anywhere, and they are continuous (or practically so, even when pulsed). Stray reflections from glass, jewelry, or any shiny object, can result in permanent eye injury. Anything above 5mW should be treated with the same respect as a fire arm. Be careful! Lasers aren't toys.
