Hi guys,
I´ve got a pretty cheap source for 120mW 520nm Os..m laser diode.
Price: 80€ plus paypal and shipping and VAT for EU customers.

You can buy them cheaper from Laserlands.

How sure are you that you will get the B1 version instead of B2?

B1 = 120mW
B2 = 90mW

are the beam specs the same?

Yes, the specs are the same except the output power.
Senior Member
If you read the specs it shows a threshold of current of 140-200mA. Which is the same current of the B1. (120mW version) http://www.prophotonix.com/uploads/P...3-27_B1_B2.pdf
Are you sure you have the B1 version? Its not listed in the OP. Did you get a spec sheet??? Did you test your diodes??? I dont see any proof that yours are B1. I'm not saying they are not, but your OP is pretty vague.

Yes, I am sure, because:
- I test the diodes I get, not each but at least 30% of them when there is a chance that it could be a wrong diode
- I buy them from a German supplier who wont fool me, because my lawyer and the lawyers of my customers would cut his head off when he fools me/us. So there is no need to sell me a weaker diode just to make several bucks more.

Thats good to know. I'm sure there are many members who will pay the extra $$$ for that premium. You should make that known in your OP so people feel confident buying from you.
