Na 1976, Zumsteg et al. jiri usoro hydrothermal tolite rubidium titanyl phosphate (RbTiOPO₄, nke a na-akpọ RTP) kristal. kristal RTP bụ usoro orthorhombic, mm2 isi otu, P_na21 otu oghere, nwere uru zuru oke nke nnukwu ọnụọgụ electro-optical, ọnụ ụzọ mmebi ọkụ dị elu, omume dị ala, oke mgbasa ozi sara mbara, enweghị isi, ọnwụ ntinye dị ala, enwere ike iji ya rụọ ọrụ ugboro ugboro (ruo 100). kHz), wdg. A gaghị enwe akara isi awọ n'okpuru irradiation laser siri ike. N'ime afọ ndị na-adịbeghị anya, ọ ghọrọ ihe a ma ama maka ịkwadebe electro-optic Q-switches, karịsịa maka usoro laser ugboro ugboro..

The akụrụngwa nke RTP decompose mgbe ha na-agbaze, na-apụghị toro site ot agbaze Anam Udeme. Ọtụtụ mgbe, a na-eji fluxes eme ihe iji belata ebe mgbaze. N'ihi na mgbakwunye na nnukwu ego nke flux na akụrụngwa, ọ’Ọ siri ezigbo ike itolite RTP na nnukwu nha yana oke mma. N'afọ 1990, Wang Jiyang na ndị ọzọ jiri usoro mgbanwe ọrụ onwe onye nweta otu kristal RTP zuru oke na nke enweghị agba. mm×44 mm×34 mm, ma duzie ọmụmụ ihe gbasara arụmọrụ ya. Na 1992 Oseledchiket al. jiri usoro mgbanwe ọrụ onwe onye yiri nke ahụ iji too kristal RTP nwere nha 30 mm×40 mm×60 mm na ọnụ ụzọ mmebi laser dị elu. Na 2002 Kanan et al. jiri obere ego MoO mee ihe₃ (0.002 mol%) dị ka mgbanwe na usoro mkpụrụ-elu iji too kristal RTP dị elu nke nwere nha ihe dịka 20 mm. Na 2010 Roth na Tseitlin ji [100] na [010] mkpụrụ ntụzịaka, n'otu n'otu, na-eto nnukwu RTP site na iji usoro mkpụrụ n'elu.

E jiri ya tụnyere KTP kristal nke ụzọ nkwadebe ya na ihe ndị na-ahụ maka electro-optical yiri ya, ihe mgbochi nke kristal RTP bụ 2 ruo 3 iwu nke ịdị elu (10)⁸ Ω·cm), yabụ enwere ike iji kristal RTP dị ka ngwa mgbanwe EO Q na-enweghị nsogbu mmebi electrolytic. N'afọ 2008, Shaldinet al. jiri usoro mkpụrụ dị n'elu tolite otu kristal RTP nke nwere ihe mgbochi nke ihe dịka 0.5×10¹² Ω·cm, nke bara ezigbo uru maka EO Q-switchs nwere oghere doro anya buru ibu. Na 2015 Zhou Haitaoet al. kọrọ na kristal RTP nwere ogologo axis karịrị 20 A na-etolite mm site na usoro hydrothermal, na resistivity bụ 10¹¹~10¹² Ω·cm. Ebe ọ bụ na kristal RTP bụ kristal biaxial, ọ dị iche na kristal LN na kristal DKDP mgbe ejiri ya dị ka EO Q-gbanwee. Otu RTP n'ime ụzọ abụọ ahụ ga-atụgharịrịrị 90°na ntụziaka nke ìhè iji kwụọ ụgwọ maka eke birefringence. Nhazi a ọ bụghị naanị na-achọ ịdị n'otu anya dị elu nke kristal n'onwe ya, kamakwa ọ na-achọ ka ogologo kristal abụọ ahụ dị nso dị ka o kwere mee, iji nweta oke mbibi dị elu nke Q-switch.

Dị ka ihe kacha mma EO Q-mgbanweing ihe na ugboro ugboro ugboro ugboro, RTP crystals dabere na mmachi nke nha nke na-agaghị ekwe omume maka nnukwu oghere doro anya (oghere kachasị nke ngwaahịa azụmahịa bụ naanị 6 mm). Ya mere, nkwadebe nke kristal RTP ya na nnukwu nha na ogo dị elu nakwa nke dakọtara usoro nke RTP ụzọ abụọ ka mkpa nnukwu ego nke ọrụ nyocha.
