Ngowe-1976, Zumsteg okqhubekayo. wasebenzisa indlela ye-hydrothermal yokukhulisa i-rubidium titanyl phosphate (RbTiOPO4, ekubhekiselwa kuyo njenge-RTP) ikristale. Ikristale ye-RTP yinkqubo ye-orthorhombic, mmIqela lamanqaku ama-2, Pn / A21 Iqela lesithuba, lineengenelo ezibanzi ze-electro-optical coefficient, ukukhanya okuphezulu komonakalo, ukukhanya okuphantsi, ukuhanjiswa okubanzi, ukungahambi kakuhle, ilahleko ephantsi yokufaka, kwaye ingasetyenziselwa ukuphindaphinda umsebenzi wokuphindaphinda (ukuya kwi-100). kHz), njl. Kwaye akuyi kubakho manqaku angwevu phantsi kweradiation ye-laser enamandla. Kwiminyaka yakutshanje, iye yaba yinto edumileyo yokulungiselela i-electro-optic Q-switches, ilungele ngakumbi iinkqubo ze-laser zokuphindaphinda..
Izinto eziluhlaza ze-RTP ziyabola xa zinyibilika, kwaye azinakukhuliswa ngeendlela eziqhelekileyo zokutsalwa kwenyibilika. Ngokuqhelekileyo, i-fluxes isetyenziselwa ukunciphisa indawo yokunyibilika. Ngenxa yokongezwa kwesixa esikhulu sokuguquguquka kwizinto eziluhlaza, oko’Kunzima kakhulu ukukhula i-RTP enobungakanani obukhulu kunye nomgangatho ophezulu. Ngo-1990 u-Wang Jiyang kunye nabanye basebenzisa indlela yokuzisebenzela ukuze bafumane ikristale engenambala, epheleleyo kunye neyunifomu ye-RTP enye ye-15. mm×44 mm×34 mm, kwaye yenze uphononongo olucwangcisiweyo malunga nokusebenza kwayo. Ngowe-1992 Oseledchikokqhubekayo. wasebenzisa indlela efanayo yokuzisebenzela ukukhulisa iikristale ze-RTP ezinobungakanani be-30 mm×40 mm×60 mm kunye nomda womonakalo we-laser ophezulu. Ngo-2002 eKannan okqhubekayo. wasebenzisa imali encinci ye-MoO3 (0.002 mol%) njenge-flux kwindlela yembewu ephezulu yokukhulisa iikristale ze-RTP ezikumgangatho ophezulu kunye nobukhulu obumalunga ne-20 mm. Ngo-2010 i-Roth kunye ne-Tseitlin basebenzisa i- [100] kunye ne- [010] imbewu yendlela, ngokulandelelana, ukukhulisa i-RTP yobukhulu obukhulu kusetyenziswa indlela yembewu ephezulu.
Xa kuthelekiswa neekristale ze-KTP ezineendlela zokulungiselela kunye neempawu ze-electro-optical ziyafana, ukuxhathisa kweekristale ze-RTP yi-2 ukuya kwi-3 imiyalelo yobukhulu obuphezulu (10).8 Ω·cm), ngoko ke iikristale ze-RTP zingasetyenziswa njenge-EO Q-ukutshintsha izicelo ngaphandle kweengxaki zomonakalo we-electrolytic. Ngo-2008 uShaldinokqhubekayo. isebenzise indlela yembewu ephezulu yokukhulisa ikristale ye-RTP yesizinda esisodwa kunye ne-resistiveivity malunga ne-0.5×1012 Ω·cm, enenzuzo kakhulu kwi-EO Q-itshintshi kunye ne-aperture enkulu ecacileyo. Kwi-2015 Zhou Haitaookqhubekayo. ingxelo yokuba iikristale ze-RTP ezinobude be-axis obukhulu kune-20 mm zakhuliswa ngendlela ye-hydrothermal, kunye ne-resistivity yayiyi-1011~1012 Ω·i-CM. Ekubeni i-crystal ye-RTP i-crystal ye-biaxial, ihluke kwi-crystal ye-LN kunye ne-DKDP crystal xa isetyenziswe njenge-EO Q- switch. I-RTP enye kwisibini kufuneka ijikelezwe ngama-90°kwicala lokukhanya ukuhlawula i-birefringence yendalo. Olu luyilo alufuni kuphela ukufana okuphezulu kwe-crystal optical ngokwayo, kodwa kufuna ukuba ubude beekristali ezimbini busondele ngokusemandleni, ukufumana umlinganiselo ophezulu wokuphela kwe-Q-switch.
Njengomhle kakhulu EO Q-switchnge impahla nge ukuphindaphinda okuphindaphindiweyo, ikristale ye-RTPs ngokuxhomekeke kumda wobungakanani into engenakwenzeka enkulu indawo ecacileyo (i-aperture ephezulu yeemveliso zorhwebo yi-6 mm kuphela). Ngoko ke, ukulungiswa kweekristale ze-RTP kunye ubukhulu obukhulu kunye nomgangatho ophezulu kunye ne ukuthelekisa ubuchule ye Izibini ze-RTP sisafuna inani elikhulu umsebenzi wophando.
