Mohato o tlase oa mocheso barium metaborate (β-BaB₂O₄, BBO for short) kristale ke ea tripartite crystal system, 3m sehlopha sa ntlha. Ka 1949, Levinle al. sibollotse boemo bo tlase ba mocheso barium metaborate BaB₂O₄ motsoako. Ka 1968, Brixnerle al. sebelisa BaCl₂ joalo ka flux ho fumana kristale e bonaletsang joaloka nale e le 'ngoe. Ka 1969, Hubner o ile a sebelisa Li₂O e le flux ho hōla 0.5mm×0.5mm×0.5mm le lekanya ya data ya motheo ya segokanyipalo, lisele tse parameters le sebaka sehlopha. Kamora 1982, Fujian Institute of Matter Structure, Chinese Academy of Sciences e ile ea sebelisa mokhoa oa kristale ea letsoai e qhibilihisitsoeng ho holisa kristale e le 'ngoe e kholo,' me ea fumana hore kristale ea BBO ke sesebelisoa se setle sa ultraviolet frequency-doubling material. Bakeng sa ts'ebeliso ea electro-optic Q-switching, kristale ea BBO e na le bofokoli ba coefficient e tlase ea electro-optic e lebisang ho matla a phahameng a halofo ea wave, empa e na le monyetla o ikhethang oa moeli o phahameng haholo oa tšenyo ea laser.

The Fujian Institute of Matter Structure, Chinese Academy of Sciences e entse letoto la mosebetsi oa ho hōla ha likristale tsa BBO. Ka 1985, kristale e le 'ngoe e nang le boholo ba φ67mm×14mm e ile ea hōla. Boholo ba kristale bo fihlile ho φ76mm×15mm ka 1986 le φ120mm×23mm ka 1988.

Ho hola ha likristale ka holim'a tsohle ho sebelisa mokhoa oa kristale oa letsoai le qhibilihisitsoeng (o tsejoang hape e le mokhoa oa top-seed-crystal method, flux-lifting method, joalo-joalo). Sekhahla sa khōlo ea kristale kac- tataiso ea axis e lieha, 'me ho thata ho fumana kristale e telele ea boleng bo holimo. Ho feta moo, coefficient ea electro-optic ea BBO kristale e batla e le nyane, 'me kristale e khuts'oane e bolela hore ho hlokahala matla a phahameng a ho sebetsa. Ka 1995, Goodnole al. e sebelisitse BBO e le lisebelisoa tsa electro-optic bakeng sa EO Q-modulation ea Nd: YLF laser. Boholo ba kristale ena ea BBO e ne e le 3mm×3mm×15mm(x, y, z), 'me ho ile ha amoheloa mokhoa oa ho feto-fetoha oa lentsoe. Le hoja karo-karolelano ea bolelele ba bolelele ba BBO ena e fihla ho 5: 1, motlakase oa kotara-wave o ntse o fihla ho 4.6 kV, e leng hoo e ka bang linako tse 5 tsa EO Q-modulation ea kristale ea LN tlas'a maemo a tšoanang.

E le ho fokotsa matla a ho sebetsa, BBO EO Q-switch e sebelisa likristale tse peli kapa tse tharo hammoho, tse eketsang tahlehelo ea ho kenya le litšenyehelo. Nickelle al. fokotsa matla a halofo ea maqhubu a kristale ea BBO ka ho etsa hore leseli le fete ka har'a kristale ka makhetlo a 'maloa. Joalokaha ho bontšitsoe setšoantšong, lebone la laser le feta ka kristale ka makhetlo a mane, 'me ho lieha ha mohato ho bakoang ke seipone se phahameng sa ho bonahatsa se behiloeng ho 45 ° se ile sa lefshoa ke leqhubu-leqhubu le behiloeng tseleng ea optical. Ka tsela ena, motlakase oa halofo ea wave oa BBO Q-switch ena e ka ba tlase ho 3.6 kV.

Ka 2011 Perlov le al. e sebelisitse NaF joalo ka flux ho holisa kristale ea BBO ka bolelele ba 50mm hoc- tataiso ea axis, 'me e fumane sesebelisoa sa BBO EO se nang le boholo ba 5mm×5mm×40mm,' me ka ho lumellana ha pono ho molemo ho feta 1 × 10⁻⁶ cm⁻¹, e finyellang litlhoko tsa EO Q-switching applications. Leha ho le joalo, potoloho ea kholo ea mokhoa ona e feta likhoeli tsa 2, 'me litšenyehelo li ntse li le holimo.

Hajoale, palo e tlase e sebetsang ea EO ea kristale ea BBO le bothata ba ho holisa BBO ka boholo bo boholo le boleng bo holimo bo ntse bo thibela ts'ebeliso ea BBO ea EO Q-switching. Leha ho le joalo, ka lebaka la sekhahla se phahameng sa tšenyo ea laser le bokhoni ba ho sebetsa ka makhetlo a mangata a pheta-phetoang, kristale ea BBO e ntse e le mofuta oa lisebelisoa tsa EO Q-modulation tse nang le boleng ba bohlokoa le bokamoso bo tšepisang.
