How do you use LBO with a green laser? Would the LBO replace the YV04?

yes BF, you'r right. But i saw how it was easy to got 532 nm with a pump and ndyag+ktp glued. In this setup we just needed to find the correct orientation of diode to the Nd: yag to have the max output (ndyag is sensitive to polarization of the pump).
Here the major problem is that the crystal are not glued together (yag+bibo) they are separate, we must find the "phase matching" plus, *the conversion efficiency is lower than KTP *so we need high pump power which mean "active cooling" for the pump and cristal... and we must deal with lens too...... no words to the mirror output too...
in this experience we need high precision tool (that can carry the crystal (we can't touch them because we can destroy the coating), and that can rotate them) too much difficult ??
But it's... research ! so fascinating and *also so....disappointing! (+$$$), theory is far far far away from practice, but i think we could do it with HUGE time....
i will ask my teacher about some homemade DPSS;


HENRYSTAL *Can you take a photo of a WORKING unit like your diagram ? have you ever tried to align them ?? please tell us ! *

, so if you make a low power 473,the bibo is better ,i
low power mean 70-100 mw ?
473 nm output as a function of incident power
we have the yag+bibo crystal *that can be output 70-100mm 473[ch12290]
The phase matching :type 1,theta 18. 3, phi 90. 0

By that graph your saying that a 2 Watt pump diode could output 180mW of 473nm. Could you please create a video or take a picture of this? If that information is accurate, your crystals would sell an huge amount.

i noticed on the first few post you offer some samples, i have an old green laser pointer and i seem to have satureated the crystal, so i have a good pump that i might be able to extract, but i need a good quality large crystal

Could you send me a total price for the KTP-YV04 in a copper, or brass holder. For a 1W pump. And I don't need the Laser diode.

And whats shipping to US?

And can you post a picture of your copper, or brass holder. I also need the dimensions.
The brass holder is Dia8mm and Dia7.5mm,the length is 4mm.
I can give you the sample for free,but you must pay for the shipping.

[/quote]

How much is the charge for shipping to the US? For that sample.
