A gold surface is a good indicator that they are meant for CO2 lasers. Could be wrong, but I doubt it

2 3V Green Laser Diode GDL 7050A | eBay

Very high quality green dpss module, can do around 100mW if properly driven. Listing also contains specsheet. I would like one myself, but I need to get rid of another green module first

Oh. Looked at the datasheet...8mrad. No thanks!

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

Well, 8mRad with a diameter of like 0.1mm. Complete DPSS heads all have beam expanders in them.

1 mm at aperture though. But yea you're right, I thought they were complete modules.

Check out this item I found on eBay: http://pages.ebay.com/link/?nav=item.view&id=321380087935&alt=web

Nope. 0.1mm was a guess, but it's actually listed here in the linked datasheet as 0.1mm:

ii-vi-suwtech.com/products/Standard%20GDL/GDL-7050A.pdf

So expanding it to your standard 1-2mm would give 0.45-0.9mRad.

relatively cheap RG yellow module, supplier seem reputable, not sure though: http://www.ebay.com/itm/550nm-600nm...ser-TTL-12V-/331595552891?hash=item4d34a2987b

Wow...I have been wondering where I could find this.
Now, I am going to try and come up with a universal host!

Or you could get the same thing with an additional blue diode and have a semi decent RGB unit for the same price. Just search "rgb laser" on ebay.

Has anybody used one of these: CVD65 905nm 13w High Power Push Laser Diode LD

For what?
They say push they mean pulse rather than cw so it's probably only good for half that cw and I don't think it even has a FAC does it?

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

I've seen that diode before, it's rated at that power for nano-seconds, for CW probably only a hundred milliwatts, if even that.

They're useless for anything we dabble with. Use the search function if you want to know why - this has been discussed in many threads.

YEP
AND while yellow laserbeams looks great... when you see it thru 'rainbow' glasses the R and G become 'unmixed' and if you were hoping for a solid yellow in Lumia you will be dissappointed as most glass will work like a diffractiojn grating
same for white lasers- AFAIK there is NO solid white LUMIA (w/laser power)


I REALLY like those white laser- set-ups easy to move to other projects if you plan for that

Pushing AixiZ to give us a GB price on their 400mW-

no sure but do think the AixiZ version is better than the o--
nes sold by LLands and Thood for about 100$
AixiZ is back ordered on these =they sold quick at $135usd
so getting us a better rpice may no be easy

AixiZ, after all must import to USA adding to the cost while LLands and Thood do not & I have been told anytime a china seller gets orders from USA they get a insentive kick back and cheaper shipping too.

AixiZ tends to trust buyers and send free replacement w/o shiiping back any defective gear ---

How would you feel about paying two shippings of 35$ each to send a pointer back to China and return AND
costing more than the laser??


things many do not consider--:shhh::yabbem:

High Power Green Laser 5W 1 2W Fire Starter Fireworks USA Seller | eBay

These look like the same ones lazerer sells only this is a USA base seller.
The add also says make offer so they could probably be had for less.
I know we can get the 7475's from China for 250 and less but multi mode greens are so sloppy looking compared to a DPSS.
However these say DIRECT DIODE!!!

This warrants further research ^^
