    Ividiyo

    I-BBO yicrystal ye-ultraviole ephindaphindwe kabini ngekristale.Iyikristale engathandekiyo engeyiyo, kunye nesalathiso esiqhelekileyo sokuthintela (akukho) sikhulu kunesalathiso sokungaqhelekanga esingaqhelekanga (ne). Zombini iindidi zodidi I kunye nohlobo lwesibini lokuthelekiswa kwesigaba kunokufikelelwa ngokulungiswa kweengile. 
    I-BBO yikristale ye-NLO esebenzayo kwisizukulwana sesibini, sesithathu nesesine se-Nd: i-YAG lasers, kunye neyona NLO crystal ilungileyo kwisizukulwana sesihlanu seHarmonic e213nm. Ukuguqulwa kokusebenza okungaphezulu kwe-70% ye-SHG, 60% ye-THG kunye ne-50% ye-4HG, kunye ne-200 mW yokuphuma kwi-213 nm (5HG).
    I-BBO ikwayikristale efanelekileyo ye-intracavity SHG yamandla aphakamileyo Nd: lasers YAG. Kwi-intracavity SHG ye-acousto-optic Q-switched Nd: i-laser ye-YAG, ngaphezulu kwe-15 W yamandla aphakathi kwi-532 nm yaveliswa yikristale ye-BBO eyenziwe nge-AR. Xa ityhilwa yimveliso engama-600 mW SHG yemowudi etshixiwe kwiNd: YLF laser, ukuphuma kwe-66 mW kwi-263 nm kwaveliswa kwiBrewster-angle-cut-BBO emgodini wangaphandle ophuculweyo.
    I-BBO inokusetyenziselwa usetyenziso lwe-EO. Iiseli ze-PBOels Pockels okanye i-EO Q-Swichi zisetyenziselwa ukutshintsha imeko yokukhanya kokudlula kuyo xa kusetyenziswa ivolthi kwii-electrode zeekristali ze-electro-optic ezinjenge-BBO. I-Beta-Barium Borate (β-BaB2O4, BBO) ene-charactors ukucaca ngokubanzi kunye namanqanaba afanayo, amanqanaba aphezulu angahambelaniyo, umda omkhulu womonakalo kunye ne-homogeneity ebonakalayo ye-optical kunye neepropro-optical iipropathi zibonelela ngamathuba anomdla kwizicelo ezahlukeneyo ze-nonlinear optical kunye nokusetyenziswa kwe-electro-optic.
    Iimpawu zeBBO crystals:
    Isigaba esibanzi sothelekiso lomgama ukusuka kwi-409.6 nm ukuya kuma-3500 nm;
    • Ingingqi ebanzi yokuhambisa ukusuka kwi-190 nm ukuya kuma-3500 nm;
    • Umlinganiso omkhulu osebenzayo wesibini-ye-harmonic-generation (SHG) malunga namaxesha amathandathu amakhulu kunalawo e-KDP.
    • Umda omkhulu wokonakaliswa;
    • Ukuhambelana okuphezulu kwe-homogeneity ene-δn ≈10-6 / cm;
    Ubushushu bebhendi ebanzi emalunga nama-55 ℃.
    Isaziso esibalulekileyo:
    I-BBO inokuthambeka okuphantsi kokufuma. Abasebenzisi bayacetyiswa ukuba babonelele ngemeko ezomileyo kuzo zombini izicelo kunye nolondolozo lweBBO.
    I-BBO ithambile kwaye ke ifuna amanyathelo okhuseleko ukukhusela indawo yayo ecoliweyo.
    Xa uhlengahlengiso lwe-engile luyimfuneko, nceda ugcine ukhumbula ukuba i-angle yokwamkela ye-BBO incinci.
