Potassium dideuterium phosphate (DKDP) he ʻano ʻano aniani aniani nonlinear me nā waiwai electro-optic maikaʻi i hoʻomohala ʻia ma 1940s. Hoʻohana nui ʻia ia i ka optical parametric oscillation, electro-optic Q-hoololi, electro-optic modulation a pēlā aku. Loaʻa iā DKDP crystalʻelua pae: ka māhele monoclinic a me ka pae tetragonal. ʻO ka pono ʻO ke aniani DKDP ka pae tetragonal no D2d-42m pūʻulu kiko a me ka ID122d -42d hui ākea. He isomorphic ka DKDPhale kūkulu o ka pāpaʻahā dihydrogen phosphate (KDP). Hoʻololi ʻo Deuterium i ka hydrogen i loko o ke aniani KDP e hoʻopau i ka mana o ka absorption infrared i hoʻokumu ʻia e ka haʻalulu hydrogen.DKDP kristal me kiʻekiʻe deuteration ioleua loaʻa iā ia ʻoi aku ka maikaʻi o ka electro-optical waiwai a ʻoi aku ka maikaʻi waiwai laina ole.
Mai ka makahiki 1970, ka hoʻomohala ʻana o ka laser Inertial Choʻopaʻapaʻa FUa paipai nui ka ʻenehana usion (ICF) i ka hoʻomohala ʻana i ke ʻano o nā kristal photoelectric, ʻoi aku ka KDP a me DKDP. E like me he electro-optical a me nonlinear optical mea hoʻohana ʻia ma ICF, ke aniani ʻo ia koi ʻia e loaʻa ka transmittant kiʻekiʻe ma na bana nalu mai kokoke-ultraviolet a kokoke-infrared, nui electro-optical coefficient a me nonlinear coefficient, paepae poino nui, a e hiki ke noho hoomakaukaud i loko puka-nui a me kiʻekiʻe-optical maikaʻi. I kēia manawa, ʻo KDP a me DKDP crystals wale nō halawai me kase koi.
Pono ka ICF i ka nui o DKDP ʻāpana e hiki i 400 ~ 600 mm. He 1-2 mau makahiki e ulu aiDKDP kristal me nui nui ma ke ʻano kuʻuna o wai hoʻoluʻu wai, no laila, nui nā hana noiʻi i hana ʻia i loaa ka ulu wikiwiki o nā kristal DKDP. Ma 1982, Bespalov et al. ua aʻo i ka ʻenehana ulu wikiwiki o ka kristal DKDP me kahi ʻāpana keʻa o 40 mm×40 mm, a hiki i ka piʻi ʻana o ka ulu ʻana i ka 0.5-1.0 mm / h, ʻo ia kahi kauoha o ka nui ma mua o ke ʻano kuʻuna. Ma 1987, Bespalov et al. Ua ulu maikaʻi nā kristal DKDP kiʻekiʻe me ka nui o 150 mm×150 mm×80 mm na e hoʻohana ana i kahi ʻenehana ulu wikiwiki like. I ka makahiki 1990, ʻo Chernov et al. loaʻa nā kristal DKDP me ka nuipaʻa o 800 g ma ka hoʻohana ʻana i ke kiko-ʻano hua. ʻO ka ulu nui o nā kristal DKDP i Z-hiki i ke kuhikuhid 40-50 mm/d, a me nā mea i loko X- a me Y-kuhikuhi hiki akud 20-25 mm/d. ʻO Lawrence Livermore Lahui Ua hana ʻo Laboratory (LLNL) i nā noiʻi he nui no ka hoʻomākaukau ʻana i nā kristal KDP nui a me nā kristal DKDP no nā pono o ka N.kūʻokoʻa Mea Hoʻolima (NIF) o USA. I ka makahiki 2012,Ua ulu nā mea noiʻi Kina he aniani DKDP me ka nui o 510 mm×390 mm×520 mm mai kahi ʻāpana DKDP maka o ke ʻano II pālua pinepine me ka nui o 430 mm hana ʻia.
Pono nā noi uila Q-switching electro-optical i nā kristal DKDP me ka ʻike deuterium kiʻekiʻe. I ka makahiki 1995, Zaitseva et al. ulu nā kristal DKDP me ka nui deuterium maʻiʻo a me ka ulu ulu o 10-40 mm/d. I ka makahiki 1998, Zaitseva et al. loaʻa nā kristal DKDP me ka maikaʻi o ka optical maikaʻi, haʻahaʻa dislocation density, kiʻekiʻe optical uniformity a me ka paepae pōʻino kiʻekiʻe ma o ka hoʻohana ʻana i ke ʻano kānana hoʻomau. I ka makahiki 2006, ua hoʻopaʻa ʻia ke ʻano hana photobath no ka mahi ʻana i ke aniani deuterium DKDP kiʻekiʻe. Ma 2015, DKDP crystals me ʻiole deuterationio o 98% a me ka nui o 100 mm×105 mm×Ua ulu maikaʻi ʻo 96 mm ma ka helu-hua ala ma ke Kulanui o Shandong o Kina. ʻO Thʻo ia ʻAʻohe hemahema macro ʻike ʻia ke aniani, a kona ʻAʻole i emi iho ka asymmetry ʻano kuhikuhi refractive ma mua o 0.441 ppm. Ma 2015, ka ʻenehana ulu wikiwikio DKDP kristal me ka iole deuterationio o 90% ua hoʻohana ʻia no ka manawa mua ma Kina e hoʻomākaukau ai Q-hoʻololimea ʻai, e hōʻoia ana e hiki ke hoʻohana i ka ʻenehana ulu wikiwiki e hoʻomākaukau i ka 430 mm anawaena DKDP electro-optical Q-switchana ʻāpana koi ʻia e ICF.
Hoʻokumu ʻia ka kristal DKDP e WISOPTIC (Deuteration> 99%)
ʻO nā kristal DKDP i hōʻike ʻia i ka lewa no ka manawa lōʻihi loaʻa iliahi delirium a me nebulaization, kahi e alakaʻi ai i ka hoʻohaʻahaʻa nui i ka maikaʻi optical a me ka lilo o ka pono hoohuli. No laila, pono e hoʻopaʻa i ka aniani i ka wā e hoʻomākaukau ai i ka electro-optic Q-switch. I mea e hoemi ai i ka noonoo malamalamama ka pukaaniani hoailonas o ka Q-hoololi a i ka mau ʻili o ka aniani, hoʻoinu pinepine ʻia ka wai hoʻohālikelike refractive i loko o ke ākea ma waena o ke aniani a me ka pukaanianis. ʻOiai wi waho kūʻē-uhi hoʻomanaʻo, tʻo ia ka hoʻouna ʻana hiki ke ua hoʻonui ʻia mai 92% a i 96% -97% (lōʻihi hawewe 1064 nm) e hoʻohana hoʻolike hoʻohālikelike ʻano hoʻopaʻapaʻa. Eia kekahi, hoʻohana pū ʻia ke kiʻi pale e like me ke ana ʻana i ka moisture-proof. Xionget al. hoomakaukau SiO2 kiʻi koloidal me nā hana o hoʻomaʻamaʻa a me ka anti-reflectima. Ua hōʻea ka transmittance i 99.7% (ka lōʻihi o ka nalu 794 nm), a hiki i ka paepae pōʻino laser i 16.9 J/cm2 (ka lōʻihi o ka nalu 1053 nm, ka laula pulse 1 ns). ʻO Wang Xiaodong et al. hoomakaukauia a pale kiʻiʻoniʻoni na hoʻohana i ka resin aniani polysiloxane. Ua hōʻea ka paepae pōʻino laser i 28 J/cm2 (ʻo 1064 nm ka lōʻihi o ka nalu, 3 ns ka laula pulse), a ua paʻa mau nā waiwai optical i ke kaiapuni me ka haʻahaʻa haʻahaʻa ma mua o 90% no 3 mau mahina.
ʻOkoʻa mai ka kristal LN, i mea e lanakila ai i ka mana o ka birefringence kūlohelohe, Hoʻohana ka DKDP crystal i ka modulation longitudinal. Ke hoʻohana ʻia ke apo electrode, ka lōʻihi o ke aniani i loko o kakaola ʻoi aku ka nui o ke kuhikuhi ma mua o ke aniani’s anawaena, i mea e loaa like ai ke kahua uila, ka mea nolaila hoonui i ka hoʻomāmā i ke aniani a ka hopena wela e alakaʻi i ka depolarization at kiʻekiʻe awelika mana.
Ma lalo o ke koi o ICF, ua hoʻomohala wikiwiki ʻia ka hoʻomākaukau, ka hana ʻana a me ka ʻenehana noiʻi o ka kristal DKDP, kahi e hoʻohana nui ʻia ai ka DKDP electro-optic Q-switches i ka laser therapy, laser aesthetic, laser engraving, laser marking, noiʻi ʻepekema. a me nā māhele ʻē aʻe o ka noi laser. Eia nō naʻe, ʻo ka deliquescence, ka poho hoʻokomo kiʻekiʻe a me ka hiki ʻole ke hana i ka haʻahaʻa haʻahaʻa, ʻo ia ka bottlenecks e kaohi ana i ka noi ākea o nā kristal DKDP.
ʻO ke kelepona DKDP Pockels i hana ʻia e WISOPTIC
