Thank you very much. Yes, I have found a couple of my green lasers, which I thought to be 5mw are actually marked 100mw and look like they are going to make excellent holography lasers.
I am new to this forum. I would like to learn from some of you with far more experience where you shop for lasers. I recently purchased a "30mw" green (532) from LaserPointerPro (China) and received a little toy laser that I would guess to be about 1mw, far dimmer than my standard 5mw lasers...
