PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

What wavelength and do you have the drivers or proper pinouts?
 





Check this thread out:


I'd like to get one of those because they appear unused, but are they? Price is, gulp, a bit high for me right now, even if a fraction of their original price, group buy anyone?
 
These were just listed: NECSEL 10WATTS AVG MAX --5PIECES LASERMODULE

Looks like these Necsels sold yesterday---- details panel in Item Specifics says Red 640nm 8W, not 10W as described in the heading, not Green---someone grabbed them, surprisingly. Currently no green Nescels are offered.

Well, the pictures showed green wavelength, I think they are green, the description was probably wrong.
 
Red at 640 and 8 watts is still of interest to me, I emailed this seller, they have more, but waiting to confirm which wavelengths. Since 10 watt red is not available, I'm betting the description was wrong, if the photo's show green.


Red uses a different design:

THe Ushio web site lists max power Necsel Red 65x 7W Laser however the spec sheet says --typical 6W ---maybe 7W -8W is max??
See: https://www.ushio.com/files/specifications/necsel-red-laser-65x-fc.pdf They also list spec for BAR config. see: https://www.ushio.com/files/specifications/necsel-red-laser-65x-bar.pdf

Nothing at all on any Green above 5W and that one in a different housing? see: https://www.ushio.com/files/specifications/necsel-green-laser-525-5w.pdf Nothing in the square config above 3W Green 53X nm nor in 52Xnm See: https://www.ushio.com/files/specifications/necsel-green-laser-53x-fc.pdf and https://www.ushio.com/files/specifications/necsel-green-laser-52x-fc.pdf

Be careful ----maybe ask the guy for the Ushio Spec sheet confirming what he says it is/they are--anyone can say anything on EBay and do for $$$

I don't know why you aren't finding 8 watts, the photo I inserted states 8 watts. Perhaps things have changed and some units are no longer being produced. I cannot find a current offering for more than 5 watts of green right now either, the seller said these 10 watt units were special prototypes, not production parts sold as their regular line. Does that mean there is an issue with them? Don't know, could be, but DashApple has a 10 watt one and got it working. At how much power? I need to ask him.

I saw the photo showing 8W but was from an Endurance written article not anything from Ushio .
Maybe is so, that the 6W Ushio module can be pushed to 8W---was looking for a spec that says 8W on Ushio web site. and all found was 6W min. in specs called 7W by Ushio in title about it.

Don't know if there was officially any "10W green "-- if it had issues or just no call for them at 10W or just pushed by someone to 10W.
Was why I was thinking would be nice to have an Ushio something that says 10W Green -- expected lifetime and electrical function specs.

Pays to be careful--a lot f people say a lot of things especially on eBay but Ushio is Ushio---maybe ask them by email?

Is all good fun, but expensive fun in this case. At least is good to know on what actual ground you stand according to the creator/manufacturer when playing with their products was my thought.

I think these greens were perhaps a special order instead of a "prototype" (EDIT: WRONG, THIS IS A SCAM REGARDING POWER OUTPUT) as the seller wrote me but they have been on ebay before and I have two of these ten watt greens I bought from them last year sitting in front of me, but with a different pin-out connector. Here's a photo DashApple took of one he was able to get working, a weird spray of green beams:


That lot of 5 did not go for that price, ebay always leaves the original price on sale when purchased under Buy It Now., the seller sold two to me the same way for 150 each before. I've seen them go as low as 89 dollars each without the fiber coupler on them too.

Yikes! If that is the best these can do I wouldn't want one. That is awful.
 
That's a huge spray coming out of the SMA-905 fiber coupled connector, here's a photo of what they look like (probably not the same model though) without the fiber coupling:



Those are two rows of 24 tiny parallel beams each, probably at close to 40 mw each if these are 2 watt output units. Further, I read a paper on the NECSEL technology used in these particular devices, each of the 48 tiny beams have a maximum of 100 mw output, theoretically, not meaning this device can reach that, but with that limit, certainly not the labeled or claimed 10 watts average by this ebay seller.



I believe these are probably 2 watt, they might just use that sticker the same way many laser manufacturers put stickers on everything they make at the highest power they might produce, but usually not the power output of any particular unit, often far less. If you only want two watts, the price at $150-175 USD isn't at all high for NOS, as they are very expensive otherwise, but to jump on the purchase because he tries to make you think (actually states that) they are ten watts? Nope, I cannot confirm they are that much and everything I find points to their being 2 watts, their higher output green offerings right now do not use this small of a form factor either.

For us, we would be better off PBS combing two 1.4 watt NDG7475 520 nm laser diodes.

Edit: The seller finally responded to my concerns, he says they are 10 watt units. Anyone else confirm that?

Here is the pinout for the above unit for PPLN heater and temperature monitoring:



I have confidence the same contacts are available on all models, the model with just the flex ribbon connector too.

Such a jungle on ebay trying to make sure what they are selling is really as claimed or not. For the future, when I see the word "prototype" and cannot confirm the output of the model number was actually manufactured, or confirm the model number at all, forget it. I suspect this seller doesn't get very many returns, so keeps representing them that way. The individuals who have posted on YouTube and here testing these units have never said they were the power level marked on them.

That sticker appears to just be a maximum possible output warning sticker they probably put on every device at 10 watts or less.
