Ngo-1976, uZumsteg et al. wasebenzisa indlela ye-hydrothermal ukukhulisa i-rubidium titanyl phosphate (RbTiOPO4, ebizwa ngokuthi i-RTP) crystal. I-RTP crystal iyisistimu ye-orthorhombic, mm2 iqembu lamaphuzu, Pna21 Iqembu lesikhala, linezinzuzo eziphelele ze-coefficient enkulu ye-electro-optical, i-threshold yokulimala kokukhanya okuphezulu, ukuhanjiswa okuphansi, ububanzi bokudlulisa okubanzi, okungeyona i-deliquescent, ukulahlekelwa kokufaka okuphansi, futhi ingasetshenziselwa umsebenzi wokuphindaphinda okuphindaphindiwe (kufika ku-100 kHz), njll. Futhi ngeke kube khona amamaki ampunga ngaphansi kwe-laser irradiation eqinile. Eminyakeni yamuva nje, sekuyinto ethandwayo yokulungiselela ama-electro-optic Q-switches, afaneleka kakhulu izinhlelo ze-laser zokuphindaphinda izinga eliphezulu..
Izinto zokusetshenziswa ze-RTP ziyabola uma zincibilika, futhi azikwazi ukukhuliswa ngezindlela ezijwayelekile zokudonsa ezincibilikayo. Ngokuvamile, ama-fluxes asetshenziselwa ukunciphisa iphuzu lokuncibilika. Ngenxa yokwengezwa kwenani elikhulu lokugeleza kwezinto zokusetshenziswa, it’Kunzima kakhulu ukukhulisa i-RTP enosayizi omkhulu kanye nekhwalithi ephezulu. Ngo-1990 u-Wang Jiyang nabanye basebenzisa indlela yokuzisiza ukuze bathole ikristalu elilodwa le-RTP elingenambala, eliphelele nelinomfaniswano elingu-15. mm×44 mm×34 mm, futhi yenze ucwaningo oluhlelekile ngokusebenza kwayo. Ngo-1992 Oseledchiket al. isebenzise indlela efanayo yokuzisiza ukuze kukhule amakristalu e-RTP anosayizi ongu-30 mm×40 mm×60 mm kanye nomkhawulo womonakalo we-laser ophezulu. Ngo-2002 Kannan et al. wasebenzisa inani elincane le-MoO3 (0.002 mol%) njengendlela yokukhula kwembewu ephezulu ukuze kukhule amakristalu e-RTP ekhwalithi ephezulu anosayizi ongaba ngu-20 mm. Ngo-2010 i-Roth kanye ne-Tseitlin basebenzisa i- [100] kanye ne- [010] imbewu eqondisayo, ngokulandelanayo, ukutshala i-RTP yosayizi omkhulu besebenzisa indlela yembewu ephezulu.
Uma kuqhathaniswa namakristalu e-KTP anezindlela zawo zokulungiselela kanye nezakhiwo ze-electro-optical ezifanayo, ukumelana kwamakristalu e-RTP kuwu-2 kuya ku-3 wama-oda wobukhulu obuphezulu (108 Ω·cm), ngakho-ke amakristalu e-RTP angasetshenziswa njengezinhlelo zokusebenza zokushintsha i-EO Q ngaphandle kwezinkinga zokulimala kwe-electrolytic. Ngo-2008 uShaldinet al. isebenzise indlela yembewu ephezulu ukuze kukhule ikristalu yesizinda esisodwa se-RTP enokumelana okungaba ngu-0.5×1012 Ω·cm, okuzuzisa kakhulu kumaswishi e-EO Q anembobo enkulu ecacile. Ngo-2015 uZhou Haitaoet al. ibike ukuthi amakristalu e-RTP anobude be-axis obukhulu kuno-20 mm zakhuliswa ngendlela ye-hydrothermal, futhi i-resistivity yayiyi-1011~1012 Ω·cm. Njengoba ikristalu ye-RTP iyikristalu eyi-biaxial, ihlukile kukristalu ye-LN kanye nekristalu ye-DKDP uma isetshenziswa njengeswishi ye-EO Q-. I-RTP eyodwa kubhangqa kufanele izungeziswe ngama-90°ohlangothini lokukhanya ukuze kunxeshezelwe i-birefringence yemvelo. Lo mklamo awudingi nje kuphela ukufana okuphezulu kwe-optical ye-crystal ngokwayo, kodwa futhi kudinga ubude bamakristalu amabili ukuba busondele ngangokunokwenzeka, ukuthola isilinganiso esiphezulu sokuqothulwa kwe-Q-switch.
Njengomuhle kakhulu EO Q-switching impahla nge imvamisa yokuphindaphinda okuphezulu, ikristalu ye-RTPs ngaphansi komkhawulo kasayizi okungenzeki kwabakhulu indawo ecacile (indawo enkulu yokuvula imikhiqizo yezentengiselwano ingu-6 mm kuphela). Ngakho-ke, ukulungiswa kwamakristalu e-RTP nge usayizi omkhulu kanye nekhwalithi ephezulu kanye ne ukufanisa ubuchwepheshe kwe RTP amapheya ngisadinga inani elikhulu umsebenzi wocwaningo.
