Stoichiometric LN Crystal

Please tell us more about the nature of your question. Are you simply looking for more information about this subject?

Stoichiometric lithium niobate single crystal has received much attention because of its excellent properties. Such as, Photoelectron Properties. The crystal can be used in SAW, electro-optic modulator, ultrahigh density electrical information storage etc.

Lithium niobate is also used as a non-linear optical material for shifting laser light through certain harmonics, thus changing the frequency of the laser light.

Which SAW are we talking about? SAW II, SAW III, SAW IV?

Even not knowing, that is soooo cool! Will the LNCs propagate eerie sounds and be able to trigger a mechanical device that cuts off someone's head? Cool!

Seriously, please refrain from using ACRONYMS, dammit.

P.S. I know about lithium niobate and it's properties through Wikipedia. It has been around for quite a while and it's properties are well understood.

How on Earth are we supposed to know what LN is?

We can supply this Crystal, anybody want to use it?

That depends - impurity level and type relative to perfect stochiometry, uniformity, dislocation density, dimensions etc. - and of course price.

LiNbO3 crystal is transparent ferro-electric crystal. Its piezo-electric and electro-optic properties have wide applications. The low acoustic loss and high surface wave velocity combine to make LiNbO3 crystal useful in surface acoustic wave devices, such as SAW filters, SAW resonators, SAW delay lines and SAW sophisticated signal compressors-signal expanders. As a piezo-electric transducer, it can be widely used in micro-positioning, sensing and modulation applications. As a non-linear optical crystal, it can be used in frequency doublers, parametric oscillator, laser Q-switches and optical waveguide substrates

Sure! I'll take a piece 1 foot long, 1/2 inch square, and the ends parallel to each other to within 1/10 λ. Thanks!!!

You forgot to have them dope it with chromium or yttrium

And they will need λ = ? or else 1/10 can be fairly open.

But if they are giving them away I'll take one chromium doped annulus cylinder 1/2 inch wide and a foot long, 1/8 of an inch thick, and the ends parallel to each other to within 1/10 λ and if it is not to much trouble make the length come out at the first and second order lasing energies of chromium so I can multi mode.

Is it possible to Q switch the lasing medium?
