Uma kuqhathaniswa ne-LN crystal evamile (CLN) enokwakheka okufanayo, ukuntuleka kwe-lithium eduze ne-stoichiometric LN crystal (SLN) kuholela ekunciphiseni okuphawulekayo kokukhubazeka kwe-lattice, futhi izakhiwo eziningi zishintsha ngokufanele.Ithebula elilandelayo libonisa umehluko omkhulu wezakhiwo ezibonakalayo.Inkampani...Funda kabanzi -
Ukubuyekezwa Kafushane kwe-Lithium Niobate Crystal kanye Nezicelo zayo - Ingxenye 3: I-Anti-photorefractive Doping ye-LN Crystal
Umphumela we-Photorefractive uyisisekelo sezinhlelo zokusebenza ze-holographic optical, kodwa futhi uletha izinkinga kwezinye izinhlelo zokusebenza ze-optical, ngakho-ke ukuthuthukisa ukumelana ne-photorefractive ye-lithium niobate crystal kuye kwanakwa kakhulu, phakathi kwazo umthetho we-doping uyindlela ebaluleke kakhulu.E...Funda kabanzi -
Ukubuyekezwa Kafushane kwe-Lithium Niobate Crystal kanye Nezicelo Zayo - Ingxenye 2: Uhlolojikelele lwe-Lithium Niobate Crystal
I-LiNbO3 ayitholakali emvelweni njengamaminerali emvelo.Isakhiwo sekristalu samakristalu e-lithium niobate (LN) sabikwa okokuqala nguZachariasen ngo-1928. Ngo-1955 uLapitskii noSimanov banikeze imingcele ye-lattice yezinhlelo ze-hexagonal kanye nezintathu ze-crystal ye-LN nge-X-ray powder diffraction analysis.Ngo-1958...Funda kabanzi -
Ukubuyekezwa Kafushane Kwe-Lithium Niobate Crystal Nezicelo Zayo - Ingxenye 1: Isingeniso
Ikristalu ye-Lithium Niobate (LN) ine-polarization ephezulu ezenzakalelayo (0.70 C/m2 ezingeni lokushisa legumbi) futhi iyikristalu ye-ferroelectric enezinga lokushisa eliphakeme kakhulu le-Curie (1210 ℃) elitholiwe kuze kube manje.I-LN crystal inezici ezimbili eziheha ukunakwa okukhethekile.Okokuqala, inemiphumela eminingi ye-super photoelectric...Funda kabanzi -
