BBO Crystal
I-BBO (ẞ-BaB2O4) yi-crystal enhle kakhulu engeyona eyemuva kwenhlanganisela yezimpawu ezihlukile: indawo ebonakalayo ebanzi, uhla olubanzi lwesigaba, ukuqina okukhulu okungekho emgqeni, umkhawulo omkhulu wokulimala, kanye nokubona okuhle kwe-homogeneity. Ngakho-ke, i-BBO ihlinzeka ngesisombululo esithandekayo sokusetshenziswa okuhlukahlukene kwe-nonlinear optical njenge-OPA, OPCPA, OPO njll.
I-BBO nayo inezinzuzo zemisebe enkulu yokwamukelwa kwe-thermal, umkhawulo omkhulu wokulimala kanye nokufakwa okuncane, ngakho-ke ilungele kakhulu ukuguqulwa okuvamisile kokuphakama okukhulu noma imisebe ye-laser evamile enamandla, isib. Isizukulwane se-harmonic seNd: YAG, Ti: Sapphire ne-Alexandrite laser radiation. I-BBO yisikristalu esihle kakhulu se-NLO esizukulwaneni sesihlanu se-harmonic yeNd: YAG laser ku-213 nm. Ikhwalithi enhle ye-laser beam (ukuhlukahluka okuncane, isimo esihle semodi, njll.) Isihluthulelo se-BBO ukuthola ukuguqulwa okuphezulu kokusebenza.
Ngaphezu kwalokho, uhla olukhulu lokudluliselwa kwe-spectral kanye nokufana kwesigaba, ikakhulukazi uhla lwe-UV, lwenza i-BBO ilungele ngokuphelele imvamisa ephindaphindwe emisebeni ye-Dye, Argon ion ne-Copper vapor laser. Zombili izinhlobo zohlobo 1 (oo-e) no-Type 2 (eo-e) ezingama-angles ezihambelana ngesigaba zingatholakala, zikhulisa inani lezinzuzo zezicelo ezahlukahlukene ze-BBO.
Xhumana nathi ngesisombululo esihle kakhulu sohlelo lwakho lokusebenzisa amakristalu we-BBO.
Amakhono we-WISOPTIC -BBO
• Ukutholwa: 1x1 ~ 15x15 mm
