Right. I'll try again: Let me know if I have this straight:

So. To summarize this thread:

lasercutter: "Can I have some application answers?"
others: "Can you provide application info?"
lasercutter: "No."
others: "Then that's not a fair request, is it?"
lasercutter: "You people are the worst."

Excellent summary of the important points--pretty much the size of it.

The guy did get useful advice actually.
These self-aggrandized types all seem to think LFP will automatically babysit their daydreams about lasers ---then do the work to spoon feed them answers and corrections to avoid any real work, knowledge, or experience of their part. Go figure.

Shows there is some truth to this: "There is no expedient to which a man will not resort to avoid the real labor of thinking" ~ Sir Joshua Reynolds

Yes it's possible this person can't go into details because they are not allowed to. I worked at such a place, Johns Hopkins Applied Physics Laboratory. I know some of the odd posts you refer to, but asking the question this poster asked seems innocuous. However, it does seem odd that whomever he is working for doesn't have engineers that would know. Perhaps it's a small company in development of a process under contract.

That's why I suspect foul play here. It's not that such companies and labs don't exist, but anybody with enough expertise to work there should already know the answers to questions such as this. That and how he immediately started insulting highly reputable members and the forum in general:tired:

If you're operating the laser in space then it's not going to stay at -100F for very long. I'd honestly be more worried abut the laser getting too hot as opposed to too cold.

Since photons refract differently depending on their energy, wavelength shifts caused by going from -100F to 100F will likely cause defocusing, so you probably won't be able to burn things from 1.5m away unless you design your focusing optics with this in mind.

As you mentioned briefly, any such facility would have experts to consult. They're doomed to failure if their engineering team has resorted to asking a public internet forum about something as trivial as thermal shock... or the operating temperatures of its own equipment.

My guess is (if it's even a real question) a highschool or personal project. I highly doubt any professional organization would be using bulk diode lasers for long-range cutting purposes anyway.

lasercutter, if by some chance you actually are part of a real organization, in the future don't refer to public forums for this kind of information. Just call the manufacturer.

A typo. The working distance is 1.5 inches

I understood that the plastic he wants to cut
is 1.5" thick. I may have read that wrong. If
so how thick is the plastic he wants to cut at
a distance of 1.5" ?

If he was working for a company that had a
covert contract he could have said so...

He's probably a guy that has an idea that he
thinks is the next Sliced Bread invention that
will make him rich.

I have seen that kind of thing before, someone comes in here and wants help, but doesn't want to expose their great idea.

I don't really have a problem with that kind of thing. I'm all for developing stuff on your own, and I don't really care whether or not they want to tell me what it's for or not. (with the exception of possible malicious intent)

The only person he hurts by not revealing information is himself.

If you're trying to test the diode then why are you asking us for the answers? Do the test yourself and find out.:banned:

edit: You're nothing but a damn troll leave the forum alone.
