So i got a laser off of eBay. It is a green 532nm "star laser pointer", when i opened it it worked just fine, a very bright green dot. When you take off the lens on top, it turns into a bright "mini flashlight". The next day i took it apart by twisting the caps off, and looked at the diode, then i put it back together. Later I tried to burn a thin black piece of paper, didn't work, so i took off the lens, and burned a hole through the paper, no fire though, i had to put the paper really close to the diode so i could be effective. I burned 3 holes into the paper, then threw it out, making sure it wont light again, i put it in some water, and turned on the laser, to see that the raw beam ( without the lens) turned into a huge spot, like i have a galaxy template over the laser. It doesn't even show the beam come from the laser, I put the lens back on and saw instead of a dot its shaped like a ring, brighter around the edges, and a light layer of green around and in the ring! Did i do something to the diode? Is it dusty, its new so it couldnt dust up so quickly
