Welcome to the forum.:wave: There is lot of information on here to help you understand Lasers. Start off by Reading the Stickys and Rules and Enjoy your Stay.
Well thanks for the welcome. The stickys are really beneficial. A lot of things to look out for.
In the meantime I'm searching the forum and stickys especially for a solution to the problem why my multimeter cannot read my diodes. Its those el cheapo $15 ones. I did set up a seperate thread to ask at http://laserpointerforums.com/f44/diode-help-60232.html
