My 200mW green DX pointer died. The pump diode burned out.

Looking to sell the crystals.(still in brass holder)

PM or E-mail me with an offer.

Im using the pointer as a host for my new 405.

The crystals are 1mm x 1mm and the brass holder is 6.85mm


Personally I cant see 200mW of green from a 1mm x anything crytal set. Maybe 30-50mW at best, was the pointer ever tested for output prior to its demise?

I used to light cigarettes with that laser. I`m pretty sure it had to be close to 200mW. Must have been one of DXs better shipments. I was very impressed with it. It`s just too bad that the diode didn`t hold up.

Anyone want to do an even trade for a PHR 803t sled or a V3 lavadrive?

I would guesstimate about 1-2W.
Originally it probably had a 1W diode, driven to more then 1W.

The crystal itself is probably the same as the one in the 5mW pointer, the only difference is the 808diode survived to whatever they pushed it to get close to 300mW.


Heck, if you feel adventurous get one of this:

If you align and cool them you will get a lot of green...probably :)

I saw somewhere on this forum that DX uses a 500mW 808nM pump diode and they probably overdrive them. That would explain why it burned out.

To answer Wannaburn`s question: No I never did check its output with a meter.

It lasted me from January to November.

I would really like a V3 lava drive circuit board, as an even trade. Otherwise it just sits in a case with the rest of the dead laser body parts.

I`ll even throw in the rest of the module.(driverboard, lenses and brass housing.

If you have an infrared 808nM, 500mW laser diode(or better) to replace the burned out one, you could get some serious green light from this crystal set.

On a good, new set of batteries, I seriously was able to light cigarettes with this thing. Chicks dig it.

Hey daedronus, I checked out that 3W 808nM C-Mound diode on ebay.

It would max out the amount of green light that could come out of these crystals, but it would be extreme overkill. They would probably saturate at less than 1W, and produce no more than maybe 300mW of green.

If I was to get that laser, the only thing I would put in front of it is a really good collumating lens. And I would of course carefully drive and cool it as well.

That would be an awesome toy to attach to a video camera(to see where you`re aiming) and pop car tires from afar.

There`s a post in the experiment/modification titled "incinerater" that demonstrates a 2W 808nM with video---VERY COOL
