6$ebay green laser,impossible to push out diode. I BROKE IT

hello... i received a mw green laser....... i was tempted to increase his power........ so i trued in everey way to open it.... but the diode seems to be fused with the pen host.

i tried with screwdriver and hammer... NOTHING. i cannot puch out it! i only broked the front part of the diode.... which cointained the crystal and the focus lense. but i am not able to puch out the IR diode

seems that some crap 5mw laser don't use a REAL module like we know... like the other sold by olike... rayfoss.... my laser use a fused IR diode... with attauched the lense part... mmhh... it is the first time i see a so much strange thing....

Those cheap pens were never really intended to be disassembled.

Ciao!

All green laser pointers, even the cheapest, are mostly the same... a small driver circuit directly connected to an IR diode, very tightly encased in a brass module and right in front of the aperture, a brass slug with the crystal, finally followed by a series of optic lenses that focus the beam.

So from what you describe, you just destroyed that thing! The brass slug with the crystal can be carefully "unglued" from the brass module to expose the diode. These are pressed tightly to have efficient heatsinking with the module's base, trying to push it out is a perillous adventure...

Why exactly did you want to pull out the diode? In no way will it give you access to the driver board to mod the laser!

As photonaholic mentioned, these are very tightly glued together to avoid anything from coming loose... It would have been much simpler to buy a $10 green module fom DX, no?

BTW Wayne, sorry about your snake, dude! It was a very nice looking critter...

...my laser is a STRANGE laser.. it have a fixed NON adjustable focus lense. ... and... do you know some laser have a LATERAL spring starting from the driver.. that touch the body of the laser? this one no... but i see that have some little metal wires....to go to ground.

now i post photo.... however the IR diode is yey inside the host

i opened other 2 green laser... the silver bottle shape.. and a kaleidoscpic laser pen. .. the best thing is often to push with a screwdriver... from the HOLE APERTURE:.... but not ON the lense.... but near the lense....there is the hard part of the focus system

do you share my opinion? push by the front hole?you must pay attention.... but... work.

Click to expand...

And lots of glue.

The most part of the ones i have disassembled, had the internal tube threaded, so also the module was screwed inside, then blocked, sometimes only with glue, some other time with a second threaded tube tightened against the threaded part of the module ..... but in some cases, they just filled all the back part with epoxy resin after have glued the module in position with loctite ..... those ones, i just throwed away, cause there's no way for take out the module without ruin it completely .....

Cheap fast assembly system, WTH ..... this with the 5-min epoxy keep the driver straight without the need to use a module holder (half of the module is glued in the epoxy too), and at the same time prevent you to dismantle it and see the bad quality of the work p)

I was surprised too when I got my first eBay greenie, they are NOTHING like the DX NewWish pens, even though they look they same on the outside. I bet everything is glued in and that's why you are having trouble getting it apart.
