Makhalidwe a LiNbO3

Kanema

LiNbO3 Crystal ili ndi mawonekedwe apadera a electro-optical, piezoelectric, photoelastic ndi nonlinear. Amakonda kwambiri. Amagwiritsidwa ntchito pakuphatikizanso kwa laserfrequency, optics nonlinear, Pockels cell, optical parametric oscillators, zida zosinthira Q zama lasers, ma acousto-opticdevices, masinthidwe opangira ma frequency a gigahertz, ndi zina zambiri. Ndi chinthu chabwino kwambiri chopanga ma waveguides, ndi zina zambiri. 
Kawirikawiri chotchinga LiNbO3 chimakhala ndi indexed ngati X kudula, Y kudula kapena Z kudula ndi kapangidwe kapangidwe kake, amathanso kuwerengedwa ndi mapangidwe amalingaliro. Kutembenuka kuchokera ku trigonal -index system kukhala wamakona ngati [u 'v' w '] ---> [uvtw] kumakwaniritsidwa ndi njira zotsatirazi:
X-cut (110) = (11-20) kapena (22-40) XRD 2theta ndi 36.56 kapena 77.73 madigiri
Y-cut (010) = (10-10), (20-20) kapena (30-30) XRD 2theta ndi madigiri 20.86,42.46,65.83.
LiNbO3 ndi MgO: LN Pockels Cell imafalitsa kwambiri kutalika kwazitali kwambiri kuyambira 420 - 5200 nm. MgO: LiNbO3 EO Crystal ili ndi zida zamagetsi zamagetsi zofananira ndi LiNbO3 Crystal koma ndizowonongeka kwambiri. Ponena za MgO: LN Crystal, chiwonetsero chazowonekera cha mawonekedwe osinthika chimasinthidwa ndikumveka kwa mawu, izi zimadziwika kuti mphamvu yamagetsi yomwe ingagwiritsidwe ntchito pazida zambiri monga ma modulators opangira mawonekedwe, ma sw switch, deflectors, mafyuluta, ma frequency switch ndi sipekitiramu owunikira. LN EO Q-switch ndi MgO: LN EO Q-switch yopangidwa ndi Coupletech ili ndi kudalirika kwakukulu komanso kutembenuka kwakukulu.
