    BBO yog qhov hloov tshiab ultraviole zaus ob npaug rau kev siv lead ua.Nws yog qhov tsis zoo uniaxial siv lead ua, nrog qhov ntsuas tsis pom tseeb (tsis muaj) loj dua qhov tsis txawv txav (ne). Ob hom I thiab hom II theem kev sib txuam yuav mus txog los ntawm kev ntsuas kom haum. 
    BBO yog qhov ua tau zoo NLO siv lead ua rau qhov thib ob, thib peb thiab thib plaub lub suab paj nruag tsim ntawm Nd: YAG lasers, thiab qhov zoo tshaj plaws NLO siv lead ua rau cov neeg muaj 5 xyoo tsim ua ke nyob rau ntawm 213nm. Cov kev hloov pauv ntawm ntau dua 70% rau SHG, 60% rau THG thiab 50% rau 4HG, thiab 200 mW tso zis ntawm 213 nm (5HG) tau txais, feem.
    BBO tseem yog cov siv lead ua zoo rau kev nkag siab SHG ntawm lub zog loj Nd: YAG lasers. Rau kev cia siab ntawm SHG ntawm ib qho acousto-optic Q-hloov Nd: YAG laser, ntau dua 15 W nruab nrab lub zog ntawm 532 nm tau tsim los ntawm AR-coated BBO siv lead ua. Thaum nws tau nqus los ntawm 600 mW SHG qhov tso tawm ntawm hom-xauv Nd: YLF laser, 66 mW tso zis tawm ntawm 263 nm tau tsim los ntawm Brewster-lub kaum sab xis-txiav BBO hauv kev kho kom zoo dua sab hauv sab.
    BBO kuj tseem siv tau rau EO applications.BBO Pockels hlwb lossis EO Q-Hloov tau siv los hloov lub xeev polarization ntawm lub teeb kis los ntawm nws thaum hluav taws xob tau thov rau cov roj hluav taws xob ntawm cov khoom siv hluav taws xob xws li BBO. Beta-Barium Borate (β-BaB2O4, BBO) nrog cov ua cim dav thiab qhov sib txuam theem, cov kab hluav taws xob tsis sib luag, kev puas tsuaj ntau thiab qhov cuam tshuam zoo tshaj plaws homogeneity thiab electro-optical zog muab kev txaus nyiam rau ntau yam kev siv hluav taws xob tsis zoo thiab cov kev siv hluav taws xob.
    Cov yam ntxwv ntawm BBO Muaju:
    • Tshaj tawm theem sib txuam tau los ntawm 409.6 nm txog 3500 nm;
    • Kev xa xov thoob plaws hauv thaj tsam ntawm 190 nm txog 3500 nm;
    • Qhov loj tshaj qhov thib ob-harmonic-tiam (SHG) coefficient txog 6 npaug ntau dua qhov tshaj ntawm KDP siv lead ua;
    • Muaj kev piam sij ntau heev;
    • High homogeneity kho qhov muag nrog δn ≈10-6 / cm;
    • Dav qhov kub thiab txias-qhov ntim txog ntawm 55 ℃.
    Cov ntawv ceeb toom tseem ceeb:
    BBO muaj qhov tsis yooj yim raug ya raws. Cov neeg siv tau qhia txog kev ua kom qhuav rau kev thov thiab khaws cia ntawm BBO.
    BBO yog tus mos thiab yog li xav tau kev ceev faj los tiv thaiv nws qhov chaw polished.
    Thaum lub kaum sab xis hloov kho yog qhov tsim nyog, thov nco ntsoov tias kev lees txais kaum sab xis ntawm BBO yog me me.
