KTA Crystal
KTA (Kaliumū Titanyle Arsenate, KTiOAsO4 ) He cryical optical nonlinear e like me KTP i kahi o ke P P i hoʻololi ʻia e As. Loaʻa iā ia nā waiwai optical non-linear optical a me electro-optical maikaʻi, e hoʻohālike i ka hoʻopili nui ʻana i ka hui o nā kikowaena o ka wahi o 2.0-5.0 µm.
Hoʻohālikelike ʻia me KTP, ʻo nā mea nui o ka KTA e loaʻa: ʻoi aku ka nui o ka nonlinear, a ʻoi aku ka lōʻihi o ka IR cut, a he liʻiliʻi hoʻi i ka absorption ma ka 3.5 µm. He haʻahaʻa ʻo KTA ka lalo o ka conductivity ionic ma mua o KTP, kahi e hoʻonā ai i ka paepae kiʻekiʻe hōʻino ai ka laser.
Hoʻohana nui ʻia ka KTA no ka noi Optical Parametric Oscillation (OPO) e hāʻawi ana i ka ikehu kiʻekiʻe hoʻololi kino (ma luna o 50%) o ka radiation laser i kālai ʻia i nā mākeke paʻa.
E kāhea aku iā mākou no ka hoʻonā maikaʻi loa no kāu noi ʻana o nā KTA crystals.
Loaʻa i ka ʻike WISOPTIC - KTA
• He homogeneity kiʻekiʻe, maikaʻi maikaʻi o loko
• ʻO ka maikaʻi o ka poli o ka papa
• Laka nui no nā ʻāpana like ʻole (e laʻa 10x10x30mm3, 5x5x35mm3)
• Kākoʻo nonlinear nui, kūmau ka huli ʻana
• pālahalaha ākea pālahalaha, nui ka laulima like me ka laulā
• nā lole AR no nā kinipōpō mai ka mālamalama ʻike a hiki i 3300 nm
• He kumukūʻai paʻakikī, lawe wikiwiki

Nā Kūlana Nui - KTA
• Koikoi kūloko kiʻekiʻe nonlinear, ka mākeke electro-optical kiʻekiʻe
• Ke kihi ʻae ākea, pā kihi pā liʻiliʻi
• pālahalaha ākea pālahalaha, nui ka laulima like me ka laulā
• Mālama mau ka dielectric liʻiliʻi, haʻahaʻa ka ionic haʻahaʻa
• Ka haʻahaʻa haʻahaʻa ma loko o ka 3-4 µm ka kiko kikoʻī ma kahi o KTP
• ka paepae hōʻino kiʻekiʻe laser
Nā ʻōnaehana waena - KTA
• OPO no ka hanauna waena o IR - a i ka 4 µm
• Ka helu a me ka wehe ʻokoʻa i ka pae waena ma waena o IR IR
• Hoʻololi uila-optical a me Q-hoʻololi
• Hoʻolau pinepine pinepine (SHG @ 1083nm-3789nm).
