Hello All,
I recently got this cheap ~25$ laser in the mail, and thought to post some quick pictures about it. A picture is worth a thousand words, no?
No, I do not have any divergence measurements, nor do I have balloon popping pictures. I bought this just to fool around with.
This one I got from the bay from the itemquickship guy - check this thread for more info and LPF discount: http://laserpointerforums.com/f45/super-beast-green-58383.html
At the time, I do not have a LPM anymore - sorry about that! Previous member tests place this laser at 80+mW, conservative.
here we see a very simple host - no safety features, just a simple on/off.
tailcap and head removed. there was some slight glue in the threads on the head. the tailcap contact itself is just a chunk of alu- nothing fancy, no springs. Please note that this laser, like most 532 lasers, is case Positive, meaning you insert the battery backwards.
retaining ring removed - there was some glue on those threads, too. nothing too hard to get out, it's not even loctite, just simple adhesive.
the driver and diode assembly pushes right out after retaining ring removal.
nice brass heatsink with an aluminum base. the laser does indeed heat up, but heatsinking travels solely through that aluminum ring - not as efficient but it'll do.
there's your driver, and the potentiometer. no need for pot modding here, I'm perfectly happy!
the lens and crystal assembly is in a plastic housing, held on by some glue of some sort. Please read this excellent guide by goninanblood for a thorough explanation on how DPSS 532nm lasers work.

Finally, a view of the back of the diode. you can see the leads of the 808nm can there.
Obligatory beamshots:
there is a little bit of mode hopping on startup, but it stabilizes after it warms up.
yes, it appears I have a disorganized room.
Of course, I do NOT recommend you use a laser like this indoors without proper safety gear. this is NOT a laser to be giving out to young kids and it will damage your vision.
Stay safe, and thank you for reading.
