1Watt 532nm Compact Laser Cube

Kudos for purchasing, reviewing and posting the summary highlights above. This I find to be both particularly tantalizing information and yet at the same time most frustrating for their lack of having documented more thorough in-depth testing or analysis.

Your welcome, but I did not pay 32$.

DEEPDYVE sells paper access cheap.

So, this little box needs a 880nm pump, the temperature needs to be held critical, and it needs to be Q-switched?? Yeh, well, "Thats So So Easy!!!"

Received this e-mail from C2C Link Corp yesterday confirming they are a distributor for this module, and reporting the same specs as received from eBay seller lasercrystals previously:

Hello, Mac

Thank you for your interest! I am the sales representative of C2C Link Corporation and I am very pleased to help you. Here are the answers for your questions,

- TEM - We did not test before because we do not have the equipment. But it is a clear circle, looks like TEM 00 model.

- Beam diameter, perpendicular and parallel - 120-150 um at the aperture of the green laser.

- Collimation, perpendicular and parallel - There is no collimator in the laser.

- Divergence - 10-15 mrad (full angle)

- %IR - less than 10 mW


Best Regards,

Cecilia Zhang

Looks like maybe an interesting project, but damn, 600 bucks for it ?? And it has no pump diode or collimator optic. Seems like these days you could get about a watt of green for that amount of cash somewhere..

Ya, pretty close at Ultralasers.

I am giving it a try, the vendor seems legit enough. The killer for me was the fact that they are selling bare chips, which talk about their ability to mount a vandate laser host and ppln crystal to a piece of silicon, and fits with their graphs of input power vs output power a lot more realistically. The stretch to go from that to the module seemed a lot more reasonable...

I will report back with my findings, how much interest would be there in a plug/play module (assuming the beam specs are compatible with modern 445nm diode, power will be just about right)? Should be dooable for under $1000, which I think is about the going rate for a watt of green

Hey, I just wanted to follow-up to see what your findings were after having one of these modules in hand. Since the eBay listing has been stuck on just 1 sold with 5 still remaining, and the lack of a follow up post, I surmise the verdict was most probably not good.

I was just thinking about this last night. Any new news? Has anyone managed to get any green out of this thing yet?

Cryptic message. I am going to change my handle to Periodicaly:Polled:Liobate.

I can give a bit of an update, I did get a hold of one of them (after fighting with my post office for about a month...) but the $600 module with wires coming out the back does indeed have a pump diode, and all that is needed for green output is a diode drive good for 4-5amps. If you want it to work with any stability you will need to mount it on a tec, but just a heatsink is fine for initial testing. Other than that I was not able to get any measurements before flying out to MIT, but the output can be compared to a normal microchip laser without the telescope, ~0.1mm diameter, huge divergence. I want to put an el chepo telescope on it (from a laser pointer) and put it on a tec to start looking at the power output, as well as get it hooked up to some modulation sources to see how well it modulates. Come christmas time I can give more details...
