565nm From LaserLandAustralia

That sounds very cheap for two of these lasers. I have my doubts. But, please, let me know how that works out for you.

I just bought 2 of them from alibaba seller, fingers crossed :bowdown:

105$ was price.

Seller said his camera doesn’t pick this color as yellow. Beam looks misaligned. Let’s open this thing to expose inner parts when it arrives.

I will be cautious then. But, you got your 565nm for a good price and it is what he claimed, right? I would hope it works out, but I have all the equipment necessary to tell the difference. ;)

I do believe he is honest. Thats not what i meant by this guy ain't what he seems. He is a professional. Not a hobbyist.

Yes, I have no doubt he supplied what he said. As unique as it is. I think this bloke is something unique too. With only 80 sales in 12 months he is not making much money from ebay sales.

Certainly worth the risk.

Personaly i dont trust Alibaba. They allow false advertising and you cant do anything if the seller rips you off. They dont allow paypal.

The Alibaba protection is meaningless. They ask the seller to solve it and thats all they do.

It does look promising. Lets hope it is.


From the Input voltage and current to the Diode it is IR pumped. The diode voltage is to low to be anything but IR.
 
Damn. It's green on my camera too.

However, it is yellower than the ~561 LED I have

Edit:
After some looking, I'm fairly certain this isn't dpss with an 808nm pump. I'm much more confident this is direct doubling a 1130nm diode. I've never seen a DPSS laser go through a diffraction grating and make a line. Defocusing the output also makes a square shape to a noticeable degree. Would explain the low price and lack of info.

But if direct doubled the line width should be half of the diode and would it really be that large? Also the beam specs don’t seem like dpss either. Odd module and wavelength it seems.
 
Did you say 475nm DPSS for 105$?! :eek:

Where, what, who, and how many mW?!! :p

It’s 565nm, although some are 575 apparently.. :) Also note, most of that $105 was shipping. :p
They are $30 each.

:thinking: I definitely see 565 and 575 Tero.
Also the output is lime green/yellow. Even your quoted image shows 575.

Seller said it’s 570-575nm. Also he said he will ship early next week. It’s too early to make any conclusions out of this.
Seller has 8-year membership and transactions over 70k usd in total.
I think this is legit one. IMO. :rolleyes:

Being directly doubled it can shift in WL because IR diodes tend to shift in WL.

Could be direct doubling. But the crystal is very inefficient. 1.75w input for 25mw out.

I am sure we will know soon what it is. They claim its DPSS and i tend to believe that.

Being a cheap chinese diode i am not surprised the wavelength varies and the width is bad.
