Used only once for about 5 minutes (adhering to the duty cycle) to impress my (now-ex) girlfriend. She was impressed, but then got all scared when I told her the real dangers of lasers and didn't want me to use it again. :D Anyway I've been buying a lot of toys and things lately and so am...

Am I right in thinking it was sometime in the 90s?

Mine was at about age 7. My neighbor and friend had just come back from the beach with a small keychain button cell red laser pointer that came with a ton of different caps. I thought it was the coolest thing ever. After that I begged my parents to get me one of my own, it took a few years...

While I do think green lasers are cooler due to the added complexity in the design, the fact that they're brighter, and you can see the beam much more easily... my personal favorite between the two is still red. Not only do I find the red color more pleasing to my eye, I think there's also some...

Is there a "best" battery type for laser pointers? Regardless - what's your favorite battery type to use with lasers, and why?

I've currently got a "<5mW" green laser and while I don't know if it's actually a <5mW since I got it from a friend and it seems to be a no-name, the beam is visible outside at night, and inside at night too if the room is dim enough. When I first got it I thought the visible beam was awesome...

I just got a laser for free from my cousin. Looks like a no name, but I'm not sure... according to the warning label it's a class IIIb 532nm, and the little instruction paper that comes with it (in a little metal case) says on it "GLOBAL", then it has an ISO 9001-2000 below it. Next to that it...

So far the only one I've seen advertised as having a continuous duty cycle is the Wicked Laser Core 5mW. Two questions: 1) Why do most other 5mW greenies (some that go for much more) only have a 30-90 second on / 20-30 second off duty cycle? I assume that the Core has a special...

I'm going to be using it for my cat, so I'd like it to be 1mW max... .5mW would be preferable, unless you guys think that it'd be too weak for this purpose. I'm looking for something solid and of high quality (i.e., something nicer than those keychain lasers you typically see for real cheap)...

Can anyone tell me if a 5mw greenie is powerful enough to produce a visible beam on a clear night? Thanks!
