I-LiNbO3 Crystal
LiNbO3 (I-Lithium Niobate) i-crystal iyinto esetshenziswayo ehlanganisa izakhiwo ze-piezoelectric, i-Ferroelectric, i-pyroelectric, i-nonlinear, i-electro-optical, i-photoelastic, njll. I-LiNbO3 inokuqina okuqinile kokushisa nokuqina kwamakhemikhali.
Njengenye yezinto ezisetshenziswe kahle ezingelona ibala elingabonakali, i-LiNbO3 ilungele izinhlobonhlobo zezicelo zokuguqula imvamisa. Isibonelo, isetshenziswa kabanzi njengama-frequency frequency we-wavelength> 1 μm kanye ne-optical parametric oscillators (OPOs) eshaywe ngo-1064 nm kanye namadivayisi we-quasi-phase-matched (QPM). Ngenxa ye-EO yayo enkulu ne-AO coefficients, iLiNbO3 I-Crystal nayo isetshenziswa kakhulu kuma-modulators wesigaba, i-waveguide substrate, i-wave acoustic wave wafers, kanye ne-Q-switch of Nd: YAG, Nd: YLF kanye ne-Ti-Sapphire lasers.
LiNbO3 kungenziwa kufakwe izakhi ezahlukahlukene, ezifana no-Er, Pr, Mg, Fe, njll, ezinikeza impahla izakhiwo ezihlukile. Isibonelo, umkhawulo womonakalo weMgO: LiNbO3 ingaphezu kokuphindwe kabili kweLiNbO emsulwa3.
Xhumana nathi ukuthola isixazululo esihle kakhulu sohlelo lwakho lokusebenza lwe-LiNbO3 amakristalu.
