New DX Green MODULES

Finally got the DX 200mW module...

It measures 106mW's. I haven't been following this thread closely... Have you guys been pot modding these?
 





Jay --

As I posted before, mine came with everything loose including the LD pump diode ring. I had to put it back together including rotation of the LD pump to crystal orientation.
I maxed at about 143 mW.

DX took their sweet time (over a month), but I finally got a "5mW" module:

DealExtreme: $7.29 5mW 532nm Green Laser Module (3V 11.9mm)

I can confirm a 1/2W resistor on the driver. No red mark anywhere.

Initially measured at 14mW peak (w/IR).

The output seemed to taper off after about 300mA (from a 3V CR2) into the driver, so I left the pot at 280mA for 40mW peak output (34mW w/out IR).

Stable output, centered beam, good output from the start and settles down in < 10 seconds. No major issues to report here.

Oh...I can confirm the driver is reverse polarity protected too. :yh:

I think I'll try my luck with a couple more...

I got a <5mw green laser pointer on ebay which seems to be the same style as those on DX. When I tried to POT mod it I turned it as high as it could while it was turned on in order to observe just how high I could push it before it broke. Just as the potentiometer topped out the laser turned off and I had thought I had broken it. Fortunately due to having broken a few 808nm LDs I knew that the diode continues to produce light but gets much hotter after it loses it's ability to lase efficiently. So I turned the potentiometer back down and the laser still works! :eek: :eek: :eek: :eek:
Not only that but it's at least 2x as bright. In addition to this with new batteries the beam is visible on a cloudy day and the dot gets a little bit warm as well. In short don't just give up on "dead" modules. By the way does anyone have a clue how much power this outputs? On another note it is worth the effort to try putting a better diode in one of these devices when it breaks.
 
I have both DX & O-like 200mw modules
The O-like crystals are huge in comparison to these DX 200mw modules & the beams blatantly loads better
Killed my DX 200mw @ 380mA, which is allot less than my 3v O-like at factory preset current.

Im not bothered about the loss at that price & did not expect much after seeing that crystal.

but Id rather pay the extra for proper essembly & alignment & a nice crystal than get cheated on DX junk that's got glue splattered all over the lens to prevent adjustment.
BTW Deal Extreme block negetive reviews as I discovered so peeps keep buying no doubt.
