welcome to LPF! [smiley=vrolijk_26.gif] I'm sure that everyone here will make you feel right at home. LPF is a great place to learn about DIY lasers. There is a wealth of information to be found here if you are willing to look for it.
If you really get stuck and can not find what you need, someone will usually point you in the right direction... but be sure to do your homework first.
