Question

[Song]

well then, maybe your customer means IR and not UV. better clarify it with him, or send him a tube of sun-cream

didn't know you were a commercial dude... i thought you were a noob like me, just too bored to use the search function

I need to learn more. I'm a learner here. not a businessman.
I need to expand my business, learn more knowledge is necessary.
I do try search, but no answer about this......

Now that we know you're a salesperson for a Chinese laser supplier, please can you clarify your intentions?

OK. My intentions is: why my 1.2W RGB, 640nm laser diode have two light spot, how can I fix this and give the answer to my customer.

Do you mean two red beams? That is usually because the red is using two 640nm diodes combined with a PBS cube which has come out of alignment. Look at this thread for assistance:

Y'know what, I'll shut up....

Was it Topiclight where we asked for specs and were told by the salesperson that their boss wouldn't let them tell us, or was that somewhere else?

iirc that was apollo, the french guy living in china...

Ah yes, brain overload....

Could you please stop writing anything in my post? I can sent you my 1.2W RGB laser light which made with CNI laser diode, and can you stop saying anything in my post?
Thank you for your spam that I'm a businessman, and I'm form Topic Light Co.,Ltd, and I have nothing know about the laser.
But this is NOTHING help to my question.
I think you don't like me, so stop spamming here, please.
You seems like a justice in this forum, I can't bear your word.

So, am I right in thinking you sold a laser projector to a customer, they now have a problem, so they asked you, you don't know, so you are using this forum as your tech support source?

This feels a bit like DJTraximus a while back who was box shifting but had no knowledge of what he was selling...

I appreciate Song is trying to learn about lasers, but surely you should know about the product you are selling before you start shifting them. Was it Topiclight where we asked for specs and were told by the salesperson that their boss wouldn't let them tell us, or was that somewhere else?

Shutting up some more....

Song - That is the best advise I have seen as a reply. The laser module in question is in fact made of two lasers with different polarizations (one being vertical | and one horizontal - combined through a polarized beam splitter (PBS) cube to equal a +) if the optics or mirrors before the PBS get out of alignment you could get two dots :. I appreciate you reaching out to learn more about your product, seeking more knowledge should never be seen as a bad thing. This forum is here to put information out in the open, because knowledge is power. Please feel free to ask questions and learn.
