BBO Crystal
ʻO BBO (ẞ-BaB2O4) he kristal nonlinear maikaʻi loa me ka hui pū ʻana o nā helu ʻano like ʻole: ka leo ākea ākea, ākea ākea ākea ākea, coefficient nui nonlinear, kiʻekiʻe pākē nui, a me ka homogeneity optical maikaʻi loa. No laila, hāʻawi ʻo BBO i kahi hopena hoihoi no nā noi optical nonlinear e like me OPA, OPCPA, OPO etc.
Loaʻa iā BBO nā pono kūpono o ka bandwidth acceptance koʻikoʻi, ka paepae pōʻino kiʻekiʻe a me ka hoʻopili liʻiliʻi ʻana, no laila, kūpono loa ia no ka hoʻololi ʻana o ke kiʻekiʻe kiʻekiʻe a i ʻole ka mana o ka uila hihiu, e like me ka harmonic generation o Nd: YAG, Ti: Sapphire a me Alexandrite laser radiation. ʻO BBO ka makana maikaʻi loa o ka NLO no ka Pōʻalima harmonic o ka Nd: YAG laser ma 213 nm. ʻO ke ʻano o ka wī laser maikaʻi (ka divergence liʻiliʻi, ke ʻano kūpono mode, a me nā mea) i ke kī no BBO e loaʻa ai ka loli hoʻololi kiʻekiʻe.
Eia kekahi, ʻo ka nui o ka neʻe ʻana o ka hoʻokalakupua me ka hoʻokele o ka phase, ʻoiai hoʻi i ka pae UV, e hana pono ʻia ʻo BBO e kūpono no ka lōlua ʻana o ka mīkini Dye, Argon ion a me Copper. Hiki ke loaʻa nā ʻelua Type 1 (oo-e) a me nā Pae 2 (eo-e) i ke ʻano kūpono e pili ana, me ka hoʻonui ʻana i ka helu o nā pono no nā noi like ʻole o ka BBO.
E kāhea aku iā mākou no ka hoʻonā maikaʻi loa no kāu noi o nā leo leo BBO.
