I have this cheapie 532nm laser pointer and i wanted to see what was inside, to my supprise it uses the same module used in laser pointers with a potenometer just begging to be "adjusted" as it was about 4mw, when i adjusted it, the output switched TEM modes, normal TEM00, then to TEM10 and then to TEM20, i have never seen a laser pointer do this? Will the higher power destory the diode or is this somthing that happens? this is at about 10mw.
