If you were doing 1000mw in a little pen housing, it would get super hot and blow the diode. Those things don't have room for heat-sinks.

Well your 500mw and 200mw will definitely both be waaaayyyy under-spec. However, they are not necessarily 5mw. they are in the 5-30mw range most likely, but I cant be sure, because I have never seen them before. Usually lasers like that are 5-30mw though. Not all cheap lasers are necessarily the...

All the lasers look the same, but they are all different. They just simply use the same housing. Most of them will have completely different internals, but the housing just looks the same. They are not all the same, no matter how much they look alike.

Well, my very first laser (Rakuten.com - HDE 50mw Green Laser Pointer with 5 Interchangeable Heads) is that one. It is under-spec, but I would put it at about 15mw and it is very cheap. You can see the beam easily in a dark room, and it is amazing at night. You might consider that one.

Both of those lasers are a scam. Don't buy either of them, as they are both probably just overspec 5mw lasers. They are not 500mw or 1000mw as advertised. This LP 515nm 532nm 1-150 and this HL 532nm 50-300 are high quality lasers that would be up to spec. See this...

So I just ordered another 1 watt laser off of lazerer for a present, and I forgot to order it without bats. :( Will customs take my laser because of this? Hope they don't. Btw it is coming to U.S.

thanks :D

Wow...:drool:

So I just ordered this HL 532nm 50-300 laser from laserbtb. I was wondering if this laser comes with batteries, and if it is up to spec. Didn't do a ton of research, because zi need this laser ASAP. Would be a bummer to not have batteries at the ready if it doesn't come with them. Also, would...

I would definitely want a handheld

Soooo I have decided that it is time to build a laser myself. I know the basics, but have no idea what I am doing when it comes to what objects are necessary to build a laser. I was wondering if there are any threads explaining how to do your first project, and some good places to get the...

I find that whenever I have gotten or seen a laser that has lenses, there is usually one that is just a plain lense. That is just my experience.

definately the top one

Styropyro is a youtuber that does a ton of youtube tutorials, and I was wondering if anyone else has seen his videos. They are very quality and I was thinking that other people might love to see his cool DIY builds.

So was browsing ebay and found this:300mW 650nm Red High Power Burn Laser Diode Module DIY Kit with Heat Sink | eBay I own multiple lasers myself, but have never actually built my own, and I was wondering if this would be a good start for me.
