Its an honor to have officially joined these forums! I have learned almost all I know about lasers from simply reading over these forums for the last few weeks as a guest. Now that I have successfully built my own working laser, I am hooked and want to further my understanding and experience. I recently invested in a 100mW Class IIIb Green DPSS and was intrigued by its power and uniqueness enough to make me want more! Thats when I discovered this site and all the useful and informative knowledge provided by the members. Thanks to everyone for contributing to such a great community!
