BBO Crystal
BBO (ẞ-BaB2O)4) yakanakisa isina mutsara rekristaro ine musanganiswa yezvakasiyana zvezvinhu zvakasarudzika: yakajeka nzvimbo dunhu, yakafara chikamu-inoenderana renji, hombe nonlinear kukwikwidzana, yakakura kukuvadza chikumbaridzo, uye yakajeka Optical homogeneity. Naizvozvo, BBO inopa mhinduro inonakidza kune dzakasiyana-siyana nonlinear optical application dzakadai seOPA, OPCPA, OPO nezvimwe.
BBO zvakare ine zvazvakanakira yakakura yeanogamuchirwa kugamuchira bandwidth, yakakura kukuvadza chikumbaridzo uye zvidiki kutora, saka yakakodzera kwazvo kutendeuka kazhinji peak yepamusoro kana pakati simba laser radiation, semuenzaniso harmonic chizvarwa cheNd: YAG, Ti: Sapphire uye Alexandrite laser radiation. BBO ndiyo yakanakisa NLO kristaro yechishanu inoenderana chibereko cheNd: YAG laser pa 213 nm. Yakanaka laser beam mhando (diki dhivhavha, yakanaka modhi mamiriro, nezvimwewo) ndiyo kiyi yeBBO kuwana shanduko yepamusoro yekushanda.
Uye zvakare, yakakura spectral yekuparadzira huwandu pamwe nechikamu inoenderana, kunyanya muvharo yeUV, inogadzira BBO yakanyatsokodzera kutenderera kakawanda kweDhayi, Argon ion uye Copper vapor laser radiation. Dzese Type Type 1 (oo-e) uye Type 2 (eo-e) phase-yakafanana angles inogona kuwanikwa, ichiwedzera huwandu hwezvakanaka zvekushandisa kwakasiyana kweBBO.
Bata isu kune mhinduro yakanakisa yako kushandisa kweBBO makristasi.

Zvinhu Zvikuru - BBO
• Yakawanda pachena pachena (189-3500 nm)
• Yakakura chikamu chinoenderana nharaunda (410-3500 nm)
• High Optical homogeneity （δn≈10-6/ cm
• Zvikurukuru yakanyatso shanda inobudirira SHG kuenderana (ingangoita 6 nguva iya yeKDP)
