Xyoo 1976, Zumsteg ua al. siv txoj kev hydrothermal los loj hlob rubidium titanyl phosphate (RbTiOPO4, hu ua RTP) crystal. RTP siv lead ua yog ib qho system orthorhombic, mm2 point pawg, Pna21 qhov chaw pab pawg, muaj qhov zoo ntawm qhov loj electro-optical coefficient, siab lub teeb puas tsuaj, tsis tshua muaj conductivity, dav kis tau tus mob, tsis-deliquescent, tsis muaj insertion poob, thiab yuav siv tau rau siab repetition zaus ua hauj lwm (txog 100 kHz), lwm. Thiab yuav tsis muaj cov cim grey nyob rau hauv muaj zog laser irradiation. Nyob rau hauv xyoo tas los no, nws tau dhau los ua cov khoom siv nrov rau kev npaj electro-optic Q-switches, tshwj xeeb tshaj yog tsim nyog rau kev rov ua dua tus nqi laser tshuab..
Cov ntaub ntawv raw ntawm RTP decompose thaum lawv melted, thiab tsis tuaj yeem loj hlob los ntawm cov txheej txheem melting. Feem ntau, fluxes yog siv los txo qhov melting point. Vim qhov sib ntxiv ntawm ntau qhov flux hauv cov khoom siv raw, nws’s tawv heev kom loj hlob RTP nrog loj-loj thiab zoo. Xyoo 1990 Wang Jiyang thiab lwm tus tau siv txoj kev pabcuam tus kheej kom tau txais cov xim tsis muaj xim, ua tiav thiab zoo li RTP ib qho siv lead ua ntawm 15. mm×44 mm×34 mm, thiab tau ua qhov kev tshawb fawb txog nws qhov kev ua tau zoo. Xyoo 1992 Oseledchikua al. siv cov kev pabcuam tus kheej zoo sib xws los loj hlob RTP muaju nrog qhov loj ntawm 30 mm×40 mm×60 mm thiab siab laser puas pib. Xyoo 2002 Kannan ua al. siv me me ntawm MoO3 (0.002 Nws mol%) raws li cov flux nyob rau hauv cov noob saum toj kawg nkaus txoj kev loj hlob zoo RTP crystals nrog ib tug loj ntawm txog 20 mm. Hauv xyoo 2010 Roth thiab Tseitlin tau siv [100] thiab [010] cov noob kev taw qhia, feem, kom loj hlob loj-loj RTP siv cov noob saum toj kawg nkaus.
Piv nrog KTP crystals uas nws txoj kev npaj thiab cov khoom siv hluav taws xob zoo sib xws, qhov kev tiv thaiv ntawm RTP muaju yog 2 txog 3 qhov kev txiav txim siab dua (108 Ω·cm), yog li RTP muaju tuaj yeem siv los ua EO Q-hloov daim ntawv thov yam tsis muaj teeb meem electrolytic puas. Nyob rau hauv 2008 Shaldinua al. siv cov noob saum toj kawg nkaus kom loj hlob ib leeg-domain RTP siv lead ua nrog kev tiv thaiv txog li 0.5×1012 Ω·cm, uas muaj txiaj ntsig zoo rau EO Q-switches nrog qhov loj dua qhov pom tseeb. Xyoo 2015 Zhou Haitaoua al. tau tshaj tawm tias RTP muaju muaj qhov ntev ntev dua 20 mm tau loj hlob los ntawm txoj kev hydrothermal, thiab qhov resistivity yog 1011~ 1012 Ω·cm. Txij li thaum RTP siv lead ua yog biaxial siv lead ua, nws txawv ntawm LN siv lead ua thiab DKDP siv lead ua thaum siv los ua EO Q- hloov. Ib qho RTP hauv khub yuav tsum tau tig 90°nyob rau hauv cov kev taw qhia ntawm lub teeb kom compensate rau lub ntuj birefringence. Qhov kev tsim no tsis tsuas yog yuav tsum muaj qhov sib txawv ntawm qhov sib txawv ntawm cov siv lead ua nws tus kheej, tab sis kuj yuav tsum muaj qhov ntev ntawm ob lub pob zeb kom ze li sai tau, kom tau txais txiaj ntsig zoo dua ntawm Q-hloov.
Raws li ib qho zoo heev EO Q-hloovhauv khoom nrog high-repetition zaus, RTP siv lead uas raug qhov txwv ntawm qhov loj me uas yog tsis tau rau loj meej aperture (qhov siab tshaj plaws aperture ntawm cov khoom lag luam tsuas yog 6 hli). Yog li ntawd, kev npaj ntawm RTP muaju nrog loj loj thiab zoo zoo li cov sib phim txheej txheem ntawm RTP khub tseem xav tau loj npaum li cas kev tshawb fawb.
