KDP & DKDP Crystal
KDP (KH2PO4 ) a me DKDP / KD * P (KD2PO4 ) aia nō ma waena o nā mea waiwai e hoʻohana nui ʻia no NLO. Me ka lawe ʻana o ka UV maikaʻi, ka pae ākea poʻokela kiʻekiʻe, a me nā birefringence kiʻekiʻe, ma kēia mau mea e hoʻohana ʻia no ka pālua, ka huakaʻi a me ka quadrupling o Nd: YAG laser.
Me ka coefficient EO kiʻekiʻe, KDP a me DKDP crystals ākea i hoʻohana nui ʻia e hana i nā pockels cells no ka ʻōnaehana laser, e like me Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, etc. Aʻo ʻo DKDP me ka deuteration kiʻekiʻe e hoʻohana pinepine ʻia. ʻO KDP a me DKDP hiki i ka hana ʻelua ke hana i ka hoʻohālikelike o nā ʻano I a me ke ʻano II no ka SHG a me THG o 1064nm Nd: laser YAG. Kūleʻa mākou iā KDP no FGH o Nd: YAG laser (266nm).
Me kekahi o nā mea hoʻolako KDP / DKDP nui (mea hoʻokumu kumu) ma ka mākeke holoʻokoʻa holoʻokoʻa, hiki i ka WISOPTIC ka nui o ka koho i nā koho, hoʻopili (polish, coating, gold-plating, etc.). Hoʻomaopopo ka WISOPTIC i ke kumukūʻai kūpono, ka hoʻoulu ʻana, ka lawe wikiwiki ʻana a me ka wā hōʻoia hōʻoia lōʻihi o kēia mau mea.
E kāhea aku iā mākou no ka hoʻopiʻi maikaʻi loa no kāu noi no nā kristal KDP / DKDP.
Nā pono uku WISOPTIC - KDP / DKDP
• Loaʻa kiʻekiʻe helu deuteration (> 98.0%)
• He homogeneity kiʻekiʻe
• He kū maikaʻi maikaʻi loa loko
• Kūpono maikaʻi loa me ka hoʻomaʻamaʻa kiʻekiʻe
• ʻAiʻu nui no nā ʻano like ʻole a me nā ʻāpana
• He kumukūʻai paʻakikī
• Hoʻouka nui, lawe wikiwiki
