I-LiNbO3 Crystal
LiNbO3 (I-Lithium Niobate) i-crystal yindawo yokusebenza ehlanganisa iipyzoelectric, i-Ferroelectric, pyroelectric, i-nonlinear, i-electro-optical, ifotoelastic, njl. Njl LiNbO3 inozinzo olufanelekileyo lwe-thermal kunye nokuqina kweekhemikhali.
Njengenye yezinto ezibonakalayo ezibonakalayo ezingalulanga ngamehlo ezi-nonlinear, i-LiNbO3 Ilungele iintlobo ezahlukeneyo zesicelo sokuguqula imijikelezo. Umzekelo, isetyenziswa ngokubanzi njengabaphindaphindi abaphindiweyo bexesha le-wavelength> I-1 μm kunye ne-oscillator yee-octillometri (ii-OPOs) zepumitha ngo-1064 nm kunye nezixhobo ze-quasi-phase-matched (QPM). Ngenxa ye-EO enkulu kunye ne-AO coefficients, iLiNbO3 I-Crystal isetyenziswa rhoqo kwiimodyuli zesigaba, i-waveguide substrate, umphezulu we-acoustic wave wafers, kunye ne-Q-switch of Nd: YAG, Nd: YLF kunye ne-Ti-Sapphire lasers.
LiNbO3 Unokufakwa kumachaphaza ngezinto ezahlukeneyo, ezinjenge-Er, Pr, Mg, Fe, njl. njl. Umzekelo, umqobo womqobo weMgO: LiNbO3 ingaphezulu kokuphindwe kabini kweLiNbO emsulwa3.
Nxibelelana nathi malunga nesisombululo esona sisicelo sakho seLiNbO3 amakristali.
