    BBO waa muraayad cusub oo loo yaqaan 'ultraviole frequency frequency' crystal crystal 'waa' crystal 'uniaxial crystal, oo leh jajab celcelis caadi ah (maya) oo ka weyn heerka isbeddelka aan caadiga ahayn (ne) Labada nooc ee I iyo nooca II waafajinta labadaba waxaa lagu gaari karaa xagal-xagal. 
    BBO waa crystal NLO hufan oo loogu talagalay jiilka labaad, saddexaad iyo afaraad ee iswaafajinta Nd: YAG lasers, iyo kan ugu fiican NLO crystal ee jiilka shanaad ee iswaafajinta 213nm. Waxtarka badalashada in kabadan 70% ee SHG, 60% THG iyo 50% 4HG, iyo 200 mW wax soosaarka 213 nm (5HG) ayaa la helay, siday u kala horreeyaan.
    BBO sidoo kale waa muraayad wax ku ool ah oo loogu talagalay SHG ee awoodda sare Nd: YAG lasers. Daawada SHG ee acousto-optic Q-wareejisay Nd: YAG laser, in ka badan 15 W celcelis ahaan awoodda 532 nm waxaa soo saaray aaladda 'BBO crystal'. Marka ay soo saarto 600 mW SHG soosaarka qaab-quful Nd: YLF laser, soosaarka 66 mW ee 263 nm waxaa laga soo saaray BBO-xagal-gooy ah BBO oo ku taal meel banaanka ka soo baxa oo kor loo qaaday.
    BBO waxaa sidoo kale loo isticmaali karaa codsiyada EO.BBO Pockels unugyada ama EO Q-Switches ayaa loo isticmaalaa in lagu beddelo xaaladda kala-goysyada iftiinka ee dhex maraya marka koronto lagu dhejiyo elektaroodyada kiristaalo elektaroonigga ah sida BBO. Beta-Barium Borate (β-BaB2O4, BBO) oo leh muuqaallo hufan oo ballaadhan iyo wejiyada iswaafajinaya wejigooda, isugeyn ballaaran oo aan qummanayn, xadka ugu sarreeya oo waxyeello weyn leh iyo isku mid ahaanshaha indhaha iyo qalabka elektaroonigga ah ayaa bixiya fursado soo jiidasho leh oo loogu talagalay codsiyada indhaha ee aan tooska ahayn iyo codsiyada elektaroonigga ah.
    Tilmaamaha 'BBO Crystals':
    • Wareeg ballaadhan oo loo kala bixi karo oo u dhexeeya 409.6 nm ilaa 3500 nm;
    • Gobolka gudbinta ballaaran laga bilaabo 190 nm ilaa 3500 nm;
    • Isugeyn wax ku ool ah oo jiil-labaad ah (SHG) oo qiyaas ahaan 6 jeer ka weyn tan KDP crystal;
    • Xadka ugu sarreeya ee burburka;
    • Isku mid ahaanshaha indhaha oo sareeya withn ≈10-6 / cm;
    • Baaxad ballaadh-ballac ballaadhan oo qiyaastii ah 55 ℃
    Ogeysiis muhiim ah:
    BBO waxay leedahay u nugulnaanta qoyaanka. Isticmaalayaasha waxaa lagula talinayaa inay bixiyaan xaalado qalalan oo loogu talagalay labadaba arjiga iyo ilaalinta BBO.
    BBO waa mid jilicsan sidaas darteedna waxay u baahan tahay taxaddarro lagu ilaaliyo dusha sare ee dhalaalaya.
    Marka xagal-xagasha loo baahan yahay, fadlan maskaxda ku hay in xagasha aqbalaadda ee BBO ay yar tahay.
