Potassium dideuterium phosphate (DKDP) imhando ye-nonlinear optical crystal ine yakanakisa electro-optic zvivakwa zvakagadziriswa muna 1940s. Inoshandiswa zvakanyanya mu optical parametric oscillation, electro-optic Q-kuchinja, electro-optic modulation uye zvichingodaro. DKDP crystal inezvikamu zviviri: monoclinic phase uye tetragonal phase. The zvinobatsira DKDP crystal ndiyo tetragonal phase inova yeD_2d-42m point group uye ID¹²_2d -42d space group. DKDP is an isomorphicchimiro potassium dihydrogen phosphate (KDP). Deuterium inotsiva hydrogen muKDP crystal kubvisa pesvedzero ye infrared absorption inokonzerwa nehydrogen vibration.DKDP crystal ine high deuteration ratio ine zviri nani electro-optical properties uye nani nonlinear properties.

Kubva 1970s, kukura laser Inertial Confinement Fusion (ICF) tekinoroji yakakurudzira zvakanyanya kuvandudzwa kweakateedzana ephotoelectric crystals, kunyanya KDP uye DKDP. As an electro-optical uye nonlinear optical zvinhu inoshandiswa mu ICF, iyo kristaro ndizvo inodiwa kuve nepamusoro transmittance mumabhandi esaisai kubva pedyo-ultraviolet kusvika pedyo-infrared, hombe electro-optical coefficient uye nonlinear coefficient, yakakwirira kukuvara chikumbaridzo, uye kuva kukwanisa kuva gadzirirad mune hombe-aperture uye ne high-optical quality. Parizvino, KDP chete neDKDP makristasi kusangana nese zvinodiwa.

ICF inoda saizi yeDKDP chikamu kusvika 400 ~ 600 mm. Zvinowanzotora 1 ~ 2 makore kukuraDKDP crystal ine saizi yakakura kudaro nenzira yechinyakare ye aqueous solution kutonhora, saka basa rakawanda rekutsvagisa rakaitwa kuwana kukurumidza kukura kweDKDP makristasi. Muna 1982, Bespalov et al. akadzidza kukurumidza kukura tekinoroji yeDKDP crystal ine muchinjiko chikamu che40 mm×40 mm, uye chiyero chekukura chakasvika 0.5-1.0 mm / h, iyo yaiva hurongwa hwehukuru hwepamusoro kupfuura nzira yekare. Muna 1987, Bespalov et al. zvakabudirira kukura emhando yepamusoro DKDP makristasi ane saizi 150 mm×150 mm×80 mm by kushandisa nzira yakafanana yekukura nokukurumidza. Muna 1990, Chernov et al. yakawana makristasi eDKDP ane huremu hwe800 g nekushandisa poindi-nzira yembeu. Mwero wekukura weDKDP makristasi mukati Z-direction inosvikad 40-50 mm/d, uye avo vari mukati X- uye y-nzira svikad 20-25 mm/d. Lawrence Livermore National Laboratory (LLNL) yakaita tsvakiridzo yakawanda pamusoro pekugadzirira kwehukuru-hukuru KDP makristasi uye DKDP makristasi kune zvinodiwa neN.ational Ignition Facility (NIF) weU.SA. Muna 2012,Vatsvakurudzi veChinese vakagadzira kristaro yeDKDP ine saizi ye510 mm×390 mm×520 mm kubva iyo yakasvibirira DKDP chikamu chemhando II frequency kaviri nehukuru hwe430 mm hwaive made.

Electro-optical Q-switching application inoda DKDP makristasi ane yakakwira deuterium content. Muna 1995, Zaitseva et al. yakakura makristasi eDKDP ane high deuterium content uye kukura kwe10-40 mm / d. Muna 1998, Zaitseva et al. yakawana DKDP makristasi ane yakanaka optical quality, yakaderera dislocation density, yakakwirira optical kufanana uye yakakwirira kukuvara pachikumbaridzo nekushandisa inoenderera yekusefa nzira. Muna 2006, iyo photobath nzira yekurima yakakwirira deuterium DKDP crystal yakanga ine patented. Muna 2015, DKDP makristasi ane deuteration ratio ye98% uye saizi ye100 mm×105 mm×96 mm dzakabudirira kukura nepoindi-mbeu nzira muShandong University yeChina. Thndizvo crystal haina inooneka macro defect, uye zvayo refractive index asymmetry iri pasi pe0.441 ppm. Muna 2015, teknolojia yekukura nokukurumidzayeDKDP crystal ne deuteration ratio ye90% yakashandiswa kekutanga muChina kugadzirira Q-chinjaing material, zvichiratidza kuti tekinoroji yekukura nekukurumidza inogona kuiswa kugadzirira 430 mm dhayamita DKDP electro-optical Q-switch.ing chikamu inodiwa neICF.

DKDP makristasi akafumurwa kumhepo kwenguva yakareba have pamusoro delirium uye nebulization, izvo zvinozotungamira mukuderedzwa kwakanyanya mumhando ye optical uye kurasikirwa kwekushandura kushanda zvakanaka. Naizvozvo, zvinodikanwa kuvhara kristaro paunenge uchigadzirira iyo electro-optic Q-switch. Kuti uderedze kupenya kwechiedzaon hwindo rakavharwas yeQ-switch uye pa nzvimbo dzakawanda dzekristaro, refractive index inoenderana nemvura inowanzobayiwa munzvimbo pakati pekristaro nehwindos. Kunyange wkunze anti-reflective coating, tiye transmittance anogona kuva yakawedzera kubva pa92% kusvika pa96%-97% (wavelength 1064 nm) ne kushandisa refractive index matching solution. Mukuwedzera, firimu rinodzivirira rinoshandiswawo seyero-uchapupu hunyoro. Xionget al. yakagadzirirwa SiO₂ colloidal film pamwe mabasa e unyoro-uchapupu uye anti-reflection. Iyo transmittance yakasvika 99.7% (wavelength 794 nm), uye laser kukuvara chikumbaridzo chakasvika 16.9 J/cm.² (wavelength 1053 nm, pulse width 1 ns). Wang Xiaodong et al. yakagadzirirwa a firimu rinodzivirira by kushandisa polysiloxane girazi resin. Iyo laser kukuvara chikumbaridzo yakasvika 28 J / cm² (wavelength 1064 nm, pulse width 3 ns), uye optical properties yakaramba yakagadzikana munzvimbo ine hunyoro hwepamusoro kupfuura 90% kwemwedzi mitatu.

Yakasiyana neLN crystal, kuitira kuti ukunde pesvedzero yechisikigo birefringence, DKDP crystal kazhinji inotora longitudinal modulation. Kana iyo mhete electrode inoshandiswa, kureba kwekristaro mudanda gwara rinofanira kuva rakakura kudarika kristaro’s dhayamita, kuitira kuti uwane yunifomu yemagetsi munda, iyo naizvozvo kunowedzera kutorwa kwechiedza mukristaro uye the thermal effect ichaita kuti depolarization at high avhareji simba.

Pasi pekuda kweICF, kugadzirira, kugadzirisa uye kushandisa tekinoroji yeDKDP crystal yakagadziridzwa nekukurumidza, izvo zvinoita kuti DKDP electro-optic Q-swichi ishandiswe zvakanyanya mulaser therapy, laser aesthetic, laser engraving, laser yekumaka, tsvakiridzo yesainzi. uye mamwe minda yelaser application. Zvakadaro, deliquescence, kurasikirwa kwakanyanya kwekuisa uye kusakwanisa kushanda mukudziya kwakaderera zvichiri mabhodhoro anotadzisa kushandiswa kwakakura kwemakristasi eDKDP.
