These are not AR coated so they can except any IR
they are SHG 1 so they can except 554nm to 2600nm
808nm = 404nm and 946nm = 473nm and 980nm = 490nm and 1064nm = 532nm
808nm the tuning angle is 1Deg
1064nm the tuning angle is 4Deg


That proves it, These are LBO equivalents of the BBO crystals i had for Ti:sapphire lasers!

I would not suggest direct diode pumping these, even with KNBO3, which is the most efficient inorganic doubler known, the efficiency was something like 500mW in to 5mw shg out using a phase matched ECDL setup, with a direct setup it was something like 3mw out for about 5W in. In a stark contrast a q-switched laser gives much higher output- into the tens of mw with only a few hundred mw average power! KTP has a quirk that enables super efficient conversion without extreme phase matching precision.

No it does not prove anything because this is the only thing I got from you (#300234244676) Jul-05-08 15:43 Check My feed back and your records eBay Feedback Profile for frostythedadman

I leave feed back for every thing I buy and If I got 5 peaces from you I would be on your feed back 5 different times but I am only their one time. and I got a KTP from you for 1064nm to 532nm it was not from Coherent and it was much longer.

^I'm not sure that Heruursciences was trying to contradict you.. If so, I can't find it in that post.

To me it seems he is saying they are similar but not the same. He is referring to BBO, and is saying that yours are the LBO equivalent, perhaps based on those specs. I could be incorrect, however. Just trying to help keep the peace.

OOPS MY BAD

His were BBO
Ok I am sorry
Ben and ndrew2505 Have me in protect mode. so I am just on the Leary side.
I am sorry about that

You are 100% correct
I just read it wrong and I need some sleep
And I must answer one Question
These LBO's were cut to large for what the original customer ordered (out of specs ) and that's how I got them cheaper. and that's why they are not AR coated.
Ben asked why I am selling it so cheep?¿ Well how many people here would pay 1000.00 for that crystal?¿
I would be more then happy to sell one for that, but when I must compete with JDSU Thermal Diode w/ LBO Laser Crystal 3X3X20mm^3 - eBay (item 180413812247 end time Oct-29-09 20:43:15 PDT)
Well need I say more.

If you had a datasheet and could prove exactly what they were, you could easily sell them for a few hundred dollars.

One other thing, as far as I know, when you contract Coherent to make custom crystals, you sign a contract saying that they will be made and sold to you exactly how you discribe, and once they make them, you are comitted to buying them. So they would not be a custom order that someone did not want.

I'll call Steven tomorrow, if the email you quote is not true, well, we'll cross that bridge when we come to it...

Not taking any sides hear... I don't know squat about LBO crystals...

@drew..... (before you edited your post)

But IMO... he already has... (proven they are LBO crystals according to Coherent)

All anyone needs to do is contact the person at Coherent that he
supplied info about to see who is slinging the crap... rather than speculate..:cool:
Click to expand...
my opinion is as a seller he should be able to provide specifics like what ben asked for. the last pm he sent he even said he had such documentation/info... if he has it already then why is he holding it back? selling a 1000$ crystal for 95$ doesnt put his believe-ablity up any either...

and another thing is i didnt attack any one. i was laughing at the situation. its not really my fault if you considered it an attack...

p.s. here isnt the same thing as hear. i can hear perfectly... but im here right now...

Your Opinion is that of a hot air balloon, its only a big thin shell full of hot air.
And for your info I have sent it to Laserbee and ElektroFreak and jander6442 because
You called me a LULZ...

I mean that makes you just as wrong as him. Now Doesn't it.
I was going to ask you for an E mail Address and I would have sent you a forward of several email correspondence I have with Coherent. sense you are in the same league as him, I guess you screw that up. I will get some one else more suited for that job because it requires integrity.
I hope you enjoyed your laugh.

You should push down on the key that says Shift when you press the letter i that will give you a capital letter

Wow you're good.... it's a TYPO Drew.....:yabbem: edited and corrected..
 I really do know the difference...:D

BTW I never said that you ATTACKED anyone... just replying to your
post about Frosty proving what he stated (that you had deleted)....:cool:

You said Custom order
NO I Said Special order

Not necessarily
James Harper At Coherent hand picked 5 of these for me and the arrow shows the direction. these are not your ordinary production crystals.

So you need to stop twisting things around to suit your needs, arguing a point you don't have.
