OwO . Didn't know that . I owe a couple of those lasers and none of them seems to hit 10mW :/ Oh well . Better get goggles this way :)

Those lasers runs on double AA batteries . I think you won't need goggles for those . I doubt a laser that small can damage your eyes (don't point it directly of your eyes of course) . It might cause you temporary flash blindness tho .. Just be careful while using one :)

So far , all I know is dragon lasers are selling universal beam expander adapters that will only fit their be expanders .

Re: Build me a laser **405nm** for cutting Well , you can buy one from SFLasers from here : Arcane 2.0 405nm I assume a 2.5w - 3w 445nm would be as strong or stronger than a 405nm 1w . Since if you're doing cutting and slicing of items . You wouldn't be doing it from a far distance am I...

AW Batteries Sanyo Batteries Panasonic Batteries . These 3 are the best IMO . You can also look for LarryDFW :) He sells really good batteries !

Well , Both companies are good . But I personally prefer SciFi lasers ! Just got bored with the C6 host .

Dragon lasers sells a universal beam expander ! You can get it from ; : Here for the beam expander : Here for the universal adapter :)

Can't seem to reach nospin for this sick LPM :(

What are the cons of using a monocular as a beam expander ? Ive seen some threads on those who use Monoculars as beam expanders and it seemed like it worked well for them . But does it really take up a lot of light and power? How is it compared to a real Beam expander? PS. They took of the...

Title says it all , Is there any Universal adapter out there for Jetlasers Beam expander? Personally i would prefer a x10 (atleast) beam expander . I searched on DL but they only have x2 with universal adapter . JL seems to have a decent x10 Beam expander . Is anyone capable of...

Anyhow, I heard 445nm laders have a huge divergence right ? Meaning it wouldn't burn at long distances . I'm sure some of you have seen the WL video on it pooping 100 balloons . If I were to build a 3w 445nm laser will it do the same with G2 lenses ? or maybe a 3 Element glass ? Does WL 445...

Anyways thanks guys for all the fast and useful answers . xD I'll be building my first laser soon if my diode even passes through the custom :( (Probably not a too DIY one)

thanks marcuspeh! that explains alot. So now how do I not burn my driver ? is it fine to use any 2 x 3.7V battery to any driver as long as its not a boost driver ?

Hello all! I've been here for awhile now . I was wondering a lot about what kind of batteries do I use for what drivers . I heard if too much voltage is being emitted , it would fry the driver (and the diode??) So the question here is what kind of batteries do I use for what kind of drivers ...

Sure :) Thanks a lot for the headstart

I see . I guess I really have to get a LPM machine thingy too huh . How do you even adjust the watt anyways . I see a lot of voltage and current meter on pictures . What does it got to do with the Watt . Not mentioning some who talked about stability ? Seems like The amount of current...

By the way , Shakenawake. How long did your dominator 3w laser last you ? and on average how long do you use it a day ? Thanks for all the knowledge . I'm sure I'll build one soon . I'll search up for guides around here . Went pass a few some time ago . I just like to be spoonfed :p I prefer a...

That explains a lot ! Wow .Didn't know there's such thing like this . How would you recommend me to build my very own 3.5 - 4watt laser that could have a long Run cycle (about 3-5mins) with a wavelength of 445nm? Without over driving it too much of course . No wonder lasers on official sites...

Damn , they look really cool O: Looking forward to build my own laser so soon already :p I have contacted B'LORD to purchase his Dominator 3w-3.5w . Hoping to get his reply soon . hehe .

Thanks for your quick response :) I live somewhere in asia :p I have never built my own laser before but i have owned 1 , 1.5w laser before (lastyear) I have been interested in lasers ever since . My previous laser died on my because of overheating and dead diodes . Probably why im so...
