LBO Crystal
LBO (LiB3O5) jẹ iru gara gara opitika alaiṣan ti o dara pẹlu itagbajade ultraviolet ti o dara (210-2300 nm), ala bibajẹ ina lesa ati alapọsi igbohunsafẹfẹ ti o munadoko nla oniyemeji (nipa awọn akoko 3 ti kDP gara). Nitorinaa a lo LBO ni igbagbogbo lati ṣe agbega agbara giga ni keji ati ina laser harmonic laser, pataki fun awọn lacers ultraviolet.
LBO ni aafo ẹgbẹ nla ati agbegbe akoyawo, ikopọ ti kii ṣe laini giga, kemikali to dara ati awọn ohun-ini ẹrọ. Awọn ẹya wọnyi jẹ ki okuta momọ yii lagbara ti awọn ilana iṣojuuṣe opitika (OPO / OPA) ati tuntun tuntun kan ti o ni ibamu pẹlu ipele (NCPM), paapaa.
Kan si wa fun ipinnu ti o dara julọ fun ohun elo rẹ ti awọn kirisita LBO.
