    Ividiyo

    I-BBO iyi-crystal entsha ephindaphindwe kabili ye-ultraviole.Iyi-crystal engeyona i-uniaxial, enenkomba ejwayelekile yokubuyisa (engekho) enkulu kune-index refractive (ne) engavamile. Kokubili uhlobo I nohlobo II ukufana kwesigaba kungafinyelelwa ngokushuna kwe-engela. 
    I-BBO iyi-NLO crystal esebenza kahle yesizukulwane sesibili, sesithathu kanye nesine se-harmonic se-Nd: YAG lasers, ne-crystal enhle kakhulu ye-NLO yesizukulwane sesihlanu se-harmonic e-213nm. Ukusebenza kahle kokuguqulwa okungaphezu kwama-70% we-SHG, ama-60% we-THG no-50% we-4HG, kanye nokukhishwa okungu-200 mW ku-213 nm (5HG) sekutholakele, ngokulandelana.
    I-BBO iphinde ibe yikristalu elisebenza kahle le-intracavity SHG yamandla aphezulu u-Nd: YAG lasers. Okwe-intracavity SHG ye-acousto-optic Q-switched Nd: YAG laser, amandla angaphezu kuka-15 W isilinganiso esingu-532 nm yakhiqizwa nge-crystal eboshwe nge-AR BBO. Lapho ikhishwa ngokukhishwa okungu-600 mW SHG kwe-Nd ekhiywe imodi: i-laser ye-YLF, okukhipha okungu-66 mW ku-263 nm kukhiqizwe kusuka ku-Brewster-angle-cut BBO emgodini we-resonant wangaphandle othuthukisiwe.
    I-BBO nayo ingasetshenziselwa izinhlelo zokusebenza ze-EO. Amaseli we-BBO Pockels noma i-EO Q-Switches asetshenziselwa ukuguqula isimo se-polarization sokukhanya esidlula kuso lapho kusetshenziswa i-voltage kuma-electrode amakristalu we-electro-optic njenge-BBO. I-Beta-Barium Borate (β-BaB2O4, BBO) enama-charactors ukucaciseleka okubanzi nezindawo zokumatanisa isigaba, i-coefficient enkulu engekho emgqeni, umkhawulo omkhulu wokulimala kanye ne-optical homogeneity ebonakalayo kanye nezakhiwo ze-electro-optical zinikeza amathuba akhangayo wezinhlelo zokusebenza ezahlukahlukene ezingezona ezomugqa nezinhlelo zokusebenza ze-electro-optic.
    Izici zamakristalu e-BBO:
    • Ububanzi besigaba esibanzi obuqhathaniseka kusuka ku-409.6 nm kuye ku-3500 nm;
    • Isifunda esidlulisa kabanzi sisuka ku-190 nm kuye ku-3500 nm;
    • I-coefficient enkulu esebenzayo yesibili-harmonic-generation (SHG) ecishe iphindwe kasithandathu kunaleyo ye-KDP crystal;
    • Umngcele omkhulu wokulimala;
    • Ukuhlangana okuphezulu kwe-optical nge-δn ≈10-6 / cm;
    • Ububanzi bokushisa komkhawulokudonsa cishe wama-55 ℃.
    Isaziso esibalulekile:
    I-BBO inokuthambekela okuphansi kumswakama. Abasebenzisi bayelulekwa ukuthi bahlinzeke ngemibandela eyomile kukho kokubili ukufaka isicelo nokulondolozwa kwe-BBO.
    I-BBO ithambe kancane ngakho-ke idinga izinyathelo zokuvikela ukuvikela izindawo zayo ezipholishiwe.
    Lapho ukulungiswa kwe-angle kudingekile, sicela ugcine wazi ukuthi i-angle yokwamukela ye-BBO incane.
