Li-Crystal tsa LiNbO3
LiNbO3 (Lithium Niobate) kristale ke thepa e sebetsang e kopanyang likarolo tsa piezoelectric, Ferroelectric, pyroelectric, nonlinear, Electro-Optical, Photoelastic, jj. LiNbO3 e na le mafura a mangata le botsitso ba lik'hemik'hale.
E le e 'ngoe ea lisebelisoa tse sa bonahaleng tsa mahlo tse sa bonahaleng, LiNbO3 e loketse lits'ebetso tsa phetoho tse fapaneng tsa khafetsa. Mohlala, e sebelisoa haholo joaloka li-frequency frequency tsa wavelength> 1 μm le optical parametric oscillator (OPOs) e pumped ho 1064 nm hammoho le lisebelisoa tsa quasi-phase-matched (QPM). Ka lebaka la li-coefficients tsa eona tse kholo tsa EO le AO, LiNbO3 kristale e boetse e sebelisoa hangata bakeng sa li-modulators tsa phase, waveguide substrate, surface acoustic wave wafers, le Q-switching ea Nd: YAG, Nd: YLF le las-Ti-Sapphire lasers.
LiNbO3 e ka ajoa ka lintho tse fapaneng, tse kang Er, Pr, Mg, Fe, joalo-joalo, tse fanang ka thepa e ikhethang. Mohlala, monyako oa tšenyo ea MgO: LiNbO3 e feta habeli ea LiNbO e hloekileng3.
Ikopanye le rona bakeng sa tharollo e molemohali ea kopo ea hau ea LiNbO3 likristale.
