Heerkulka hoose ee barium metaborate (β-BaB₂O₄, BBO marka la soo koobo) crystal waxa iska leh nidaamka crystal tripartite, 3m kooxda dhibic. Sannadkii 1949-kii, Leviniyo al. la helay weji heerkul hooseeya barium metaborate BaB₂O₄ xarun. Sannadkii 1968-kii, Brixneriyo al. loo isticmaalo BaCl₂ sida qulqulka si aad u hesho cirbad hufan oo hal crystal u eg. 1969kii, Hubner wuxuu isticmaalay Li₂O sida qulqulka u koraan 0.5mm × 0.5mm × 0.5mm oo lagu qiyaasay xogta aasaasiga ah ee cufnaanta, xuduudaha unugyada iyo kooxda booska. Ka dib 1982, Fujian Institute of Matter Structure, Akademiyada Sayniska ee Shiinaha waxay adeegsatay habka abuur-crystal-ka dhalaalaysa si ay u koraan hal crystal weyn oo qulqulaya, waxayna ogaadeen in BBO crystal ay tahay wax aad u fiican oo ultraviolet-labalaab ah. Codsiga koronto-optic Q-bedesha, crystal BBO waxay leedahay faa'iido darro iskuxiraha korantada-optic-ga hooseeya taasoo horseedda koronto-mawjadaha nus-mawjadaha sare, laakiin waxay leedahay faa'iido aad u fiican oo ah heerka waxyeellada laysarka oo aad u sarreeya.

Machadka Fujian ee Matter Structure, Akadeemiyada Sayniska ee Shiinaha ayaa qabtay shaqo taxane ah oo ku saabsan koritaanka crystals BBO. Sannadkii 1985, hal crystal oo cabbirkiisu yahay φ67mm × 14mm ayaa la koray. Cabbirku wuxuu gaadhay φ76mm × 15mm 1986kii iyo φ120mm × 23mm 1988kii.

Koritaanka kirismaska ​​​​dhammaan ka sarreeya waxay qaataan habka abuur-crystal-ka-dhalan (sidoo kale loo yaqaan habka-seed-crystal, habka qulqulka-qaadista, iwm.). Heerka kobaca crystal eecJihada dhidibka waa mid gaabis ah, wayna adagtahay in la helo crystal dheer oo tayo sare leh. Waxaa intaa dheer, iskudarka korantada ee kristal BBO waa mid aad u yar, iyo crystal gaaban macnaheedu waa koronto shaqo oo sare ayaa loo baahan yahay. Sanadkii 1995, Goodnoiyo al. loo isticmaalay BBO sidii walxo koronto-optic ah oo loogu talagalay EO Q-modulation of Nd:YLF laser. Cabirka kristantarkan BBO wuxuu ahaa 3mm × 3mm × 15mm (x, y, z), iyo qaabaynta transverse ayaa la qaatay. Inkasta oo saamiga dhererka-dhererka ee BBO-kan uu gaaro 5: 1, korantada rubuc-mawjadaha ayaa weli ah ilaa 4.6 kV, taas oo ku saabsan 5 jeer EO Q-modulation-ka ee LN crystal shuruudo isku mid ah.

Si loo dhimo tamarta shaqaynaysa, BBO EO Q-switch waxa ay wada isticmaashaa laba ama saddex kiristaalo, taas oo kordhinaysa khasaaraha galinta iyo kharashka. Nikkeliyo al. waxay hoos u dhigtay tamarta nus-mawjadaha ee crystal BBO iyadoo ka dhigaysa iftiin dhex mara crystal dhowr jeer. Sida ku cad shaxanka, laydhka laysarka wuxuu dhex maraa crystal afar jeer, iyo daahitaanka wejiga ee ka dhashay muraayada sare ee milicsiga ee lagu dhejiyay 45 ° waxaa magdhow u ah mawjada-saxadda lagu dhejiyay waddada indhaha. Sidan, korantada-mawjadda nuska ah ee BBO Q-switch-kan wuxuu noqon karaa mid hooseeya ilaa 3.6 kV.

Sannadkii 2011, Perlov iyo al. NaF loo isticmaalay sidii qulquli si ay u koraan crystal BBO oo dhererkeedu yahay 50mmc- jihada dhidibka, oo la helay aaladda BBO EO oo cabbirkeedu yahay 5mm × 5mm × 40mm, oo leh lebbis muuqaal ah oo ka wanaagsan 1 × 10^-6 cm^-1, kaas oo buuxiya shuruudaha EO Q-beddelka codsiyada. Si kastaba ha ahaatee, wareegga kobaca ee habkani waa in ka badan 2 bilood, kharashkuna weli wuu sarreeyaa.

Waqtigan xaadirka ah, waxtarka hoose ee EO ee kristanta BBO iyo dhibaatada koritaanka BBO ee cabbirka weyn iyo tayada sare leh ayaa weli xaddidaysa codsiga BBO ee EO Q. Si kastaba ha ahaatee, iyadoo ay ugu wacan tahay heerka sare ee waxyeelada laysarka iyo awoodda lagu shaqeeyo soo noqnoqoshada sare, BBO crystal weli waa nooc ka mid ah qalabka EO Q-modulation oo leh qiimo muhiim ah iyo mustaqbal rajo leh.
