    I-BBO yikristale entsha ye-ultraviole ephindwe kabini. Yikristale engalunganga ye-uniaxial, enesalathiso esiqhelekileyo se-refractive (hayi) esikhulu kune-extraordinary refractive index (ne).Zombini uhlobo lwe-I kunye nohlobo lwe-II oluhambelanayo lwesigaba lunokufikelelwa ngokulungiswa kwe-engile.
    I-BBO yikristale ye-NLO esebenzayo kwisizukulwana sesibini, sesithathu kunye nesine se-harmonic ye-Nd: i-lasers ye-YAG, kunye ne-crystal ye-NLO engcono kakhulu ye-harmonic isizukulwana kwi-213nm.Ukuguqulwa kobuchule obungaphezulu kwe-70% ye-SHG, i-60% ye-THG kunye ne-50% ye-4HG, kunye ne-200 mW imveliso kwi-213 nm (5HG) ifunyenwe, ngokulandelanayo.
    I-BBO ikwayikristale esebenzayo ye-Intracavity SHG yamandla aphezulu Nd: YAG lasers.Kwi-intracavity SHG ye-acousto-optic Q-switched Nd: YAG laser, ngaphezu kwe-15 W ye-avareji yamandla kwi-532 nm yenziwe yi-AR-coated BBO crystal.Xa impontshwa yi-600 mW SHG isiphumo se-mode-tshix ye-Nd: YLF laser, i-66 mW ephuma kwi-263 nm yaveliswa kwi-BBO ye-Brewster-angle-cut-cut kwi-cavity yangaphandle eyongeziweyo ye-resonant.
    I-BBO ingasetyenziselwa izicelo ze-EO. Iiseli ze-BBO Pockels okanye i-EO Q-Switches zisetyenziselwa ukutshintsha imeko ye-polarization yokukhanya okudlula kuyo xa i-voltage isetyenziswe kwii-electrodes ze-electro-optic crystals ezifana ne-BBO.I-Beta-Barium Borate (i-β-BaB2O4, i-BBO) eneempawu ezicacileyo ezibanzi kunye nezigaba ezihambelana nesigaba, i-coefficient enkulu engabonakaliyo, i-threshold yomonakalo ophezulu kunye ne-homogeneity egqwesileyo ye-homogeneity kunye ne-electro-optical properties zibonelela ngeendlela ezikhangayo kwiinkqubo ezahlukeneyo ze-optical kunye ne-electro-optic applications.
    Iimpawu zeBBO Crystals:
    • Isigaba esibanzi esinokungqamana noluhlu ukusuka kwi-409.6 nm ukuya kuma-3500 nm;
    • Ummandla wothumelo olubanzi ukusuka kwi-190 nm ukuya kwi-3500 nm;
    • I-coefficient enkulu ye-second-harmonic-generation (SHG) esebenzayo malunga namaxesha ama-6 amakhulu kune-crystal ye-KDP;
    • Umda womonakalo omkhulu;
    • I-homogeneity ephezulu ye-optical kunye ne-δn ≈10-6 / cm;
    • Ubushushu obubanzi-i-bandwidth malunga ne-55℃.
    Isaziso esibalulekileyo:
    I-BBO inokuchaphazeleka okuphantsi kokufuma.Abasebenzisi bayacetyiswa ukuba babonelele ngeemeko ezomileyo zombini isicelo kunye nokugcinwa kwe-BBO.
    I-BBO ithambile ngokwentelekiso kwaye ke ngoko ifuna izilumkiso zokukhusela iindawo zayo ezikhazimlisiweyo.
    Xa ukulungiswa kwe-angle kuyimfuneko, nceda ugcine engqondweni ukuba i-angle yokumkela i-BBO incinci.
