KTP Crystal
KTP (KTiOPO4 ) ʻo ia kekahi o nā mea hana e hoʻohana i maʻamau nonlinear optical. No ka laʻana, maʻamau pinepine ia no ka hoʻolilo ʻana i nā pālua ʻelua o Nd: YAG lasers a me nā mea ʻē aʻe Nd-doped mīkini, ʻoi aku paha ma ka haʻahaʻa haʻahaʻa a ma waena iki paha. Hoʻohana nui ʻia ka KTP me ka OPO, EOM, optical wave-alakaʻi material, a i nā hui kuhikuhi.
Hōʻike ʻo KTP i kahi koina optical kiʻekiʻe, kahi ākea ākea ākea, ākea ākea ākea, kahi kihi helehelena liʻiliʻi, a me ke ʻano ʻo I a me II i ke koʻikoʻi lula-hoʻokūkū (NCPM) i kahi ākea ākea ākea. He nui ko KTP coefficient hoʻoikaika koʻikoʻi (e like me 3 mau manawa i ʻoi aku ma mua o ke KDP) a me ka paepae pōʻino kiʻekiʻe optical (> 500 MW / cm²).
Lohi ʻia nā crystals KTP maʻi maʻamau ma ka ʻalani a me ka wāwahi ("hina-track") i ka wā e hoʻohana ʻia ai i ka wā o SHG kaʻina o 1064 nm ma nā kiʻekiʻe kiʻekiʻe o nā mana kiʻekiʻe a me nā helu hoʻoiho ma luna o 1 kHz. No nā noi mana kiʻekiʻe-kiʻekiʻe, ʻo WISOPTIC e hāʻawi i ke kūloko kiʻekiʻe hina kiʻekiʻe (HGTR) KTP crystals i ulu ʻia e ka mīkini hydrothermal. He haʻahaʻa haʻahaʻa haʻahaʻa a nā kristal āpau a emi mai ka mālamalama ma mua o ke KTP maʻamau, no laila e pale aku i nā pilikia o nā mana mana harmonic, nā hoʻokele kūpono, nā aniani crystal, a me nā hiʻona.
ʻOiai kekahi o nā mea hoʻouka kumu nui KTP ma ka mākeke holoʻokoʻa holoʻokoʻa, hiki i ka WISOPTIC ke hiki i ka nui o ka koho ma ke ʻano, hoʻopili ʻana (polishing, coating), hoʻouka nui, lawe wikiwiki a hoʻolōʻihi i ka manawa o ka mana o KTP. Maikaʻi nō hoʻi he kūpono ke kūpono i kā mākou kumukūʻai.
E kāhea aku iā mākou no ka hoʻonā maikaʻi loa no kāu noi ʻana o nā KTP crystals.
Loaʻa i ka WISOPTIC - KTP
• He homogeneity kiʻekiʻe
• He kū maikaʻi maikaʻi loa loko
• ʻO ka maikaʻi o ka poli o ka papa
• Laka nui no nā ʻāpana like (20x20x40mm3, max lōʻihi 60mm)
• Kākoʻo nonlinear nui, kūmau ka huli ʻana
• ʻO nā poho haʻahaʻa haʻahaʻa
• He kumukūʻai paʻakikī
• Hoʻouka nui, lawe wikiwiki
