LBO Crystal
LBO (LiB3O5) nooc noocan oo kale ah oo aan lahayn xariijin toosan oo leh gudbinta ultraviolet-ka wanaagsan (210-2300 nm), xadka dhaawaca laser-ka oo sareeya iyo isku-xirnaanta wax ku oolka ah ee labanlaab ah (qiyaastii 3 jeer KDP crystal). Sidaas awgeed LBO waxaa badanaa loo adeegsadaa soo saarista xoogga sare ee labaad iyo saddexaad ee laydhka laser, gaar ahaan kuwa loo yaqaan 'ultraviolet lasers'.
LBO waxay leedahay faraq balaaran oo balaaran iyo gobolka daah furnaan, isku xirnaan aan toos ahayn, guryaha kiimikada iyo farsamada. Astaamahani waxay ka dhigayaan kristalkan awood u leh hababka qiyaasaha indhaha (OPO / OPA) iyo is-waafajinta wejiga non -ritritical (NCPM), sidoo kale.
Nagala soo xiriir xalka ugu fiican ee dalabkaaga ee loo yaqaan 'kiristaanka' LBO.
