hello this and really expensive
at wholesaler it costs $ 140 with LBO

As I should have said, we manufacture our own KTP, KDP, LBO, and BiBO. we don't just remarket it.
Sorry I could not be of help, but that division grows and coats really high quality crystals.

I have no doubt about the quality crystals.
but useless for me for only Beam shows

I second what mixedgas said. With a pulsed laser it is easy to get any homegrown crystal to convert some light to green. We have done some experiments on Laserfreak some time ago: http://www.laserfreak.net/forum/view...hp?f=8&t=50525 homegrown KDP with an SSY1 laser. worked well.
Doubling CW is a whole different thing, and the better the crystal (orentation, defects, coatings) the easier and more efficienct it gets so it is good to invest some money into good crystals.

Some time ago I bought vanadate + lbo from u-photoinics for my green module, but vanadate crystal did not want to work I don't know why, may bug in polarization or surfacing.... Finally i sent back crystals to china.

if the same mounting as the pictures above requires that the vanadate is well positioned
this type of installation and a big problem
the indium layer must be perfect
does not move the vanadate , when tightening the 2 screws

I happened to repeat several times for glass , must also adjust thé mirror OC

everything is really complicated in this type of installation

must be very quiet
that's why I hate CNI

do not forget to go in the right direction vanadate /LBO
