Rangahau Te ahunga whakamua o nga Tioata Whakawhiti-Q-Electro-Optic - Wāhanga 6: LGS Crystal

Lanthanum gallium silicate (La3Ka5SiO14, LGS) te karaihe no te punaha tioata tuatoru, te roopu tohu 32, te roopu mokowhiti P321 (No.150). He maha nga paanga o LGS penei i te piezoelectric, electro-optical, optical rotation, ka taea hoki te whakamahi hei rauemi laser ma te doping. I te tau 1982, ko Kaminskyet al. korerotia te tipu o nga tioata LGS doped. I te 2000, ko nga tioata LGS me te diameter o te 3 inihi me te roa o te 90 mm i whakawhanakehia e Uda me Buzanov.

Ko te karaihe LGS he rawa piezoelectric pai me te momo tapahi o te whakarea pāmahana kore. Engari he rereke mai i nga tono piezoelectric, ko nga tono hurihuri Q-whakawhiti hiko e hiahia ana kia teitei ake te kounga o te karaihe. I te tau 2003, ko Konget al. i pai te tipu o nga tioata LGS me te kore he koha tonotono ma te whakamahi i te tikanga Czochralski, ka kitea ko te ahua o te tipu ka pa ki te tae o nga tioata. I whiwhi ratou i nga tioata LGS kore tae me te hina me te hanga LGS hei EO Q-whakawhiti me te rahi o te 6.12 mm × 6.12 mm × 40.3 mm te rahi. I roto i te 2015, kotahi rōpū rangahau i roto i te Whare Wananga o Shandong i angitu te tipu LGS tioata ki te diameter 50 ~ 55 mm, roa 95 mm, me te taimaha 1100 g kahore kitea kohakore tonotono.

I te tau 2003, ka tukuna e te roopu rangahau i runga ake nei i te Whare Wananga o Shandong te kurupae taiaho kia haere i roto i te karaihe LGS kia rua nga wa ka whakauruhia he pereti ngaru hauwha ki te aukati i te awe o te hurihanga whatu, na reira i mohio ai te tono o te awe hurihuri o te karaihe LGS. Ko te LGS EO Q-whakawhiti tuatahi i mahia i muri mai ka pai te tono ki te punaha laser.

I te tau 2012, ko Wang et al. i whakaritea he LGS electro-optic Q-whakawhiti me te rahi o 7 mm × 7 mm × 45 mm, a ka mohio ki te whakaputanga o te 2.09 μm kurupae laser puhoi (520 mJ) i roto i te rama-rama i maemaa Cr,Tm,Ho: YAG pūnaha laser . I te tau 2013, 2.79 μm te kurupae laser pupuhi (216 mJ) i tutuki i roto i te rama-rama-rama Cr, Er: YSGG laser, me te whanui o te pupuhi 14.36 ns. I te tau 2016, ko Maet al. whakamahia te 5 mm × 5 mm × 25 mm LGS EO Q whakakā i roto i te Nd: LuVO4 pūnaha taiaho, ki te mohio auau tukurua o 200 kHz, e ko te auau tukurua teitei o LGS EO Q-whakawhiti pūnaha taiaho korerotia nuitia i tenei wa.

Hei rauemi whakahuri-Q EO, he pai te whakapumautanga o te pāmahana LGS me te paepae kino nui, ka taea te mahi i te auau tukurua. Engari, he maha nga raruraru: (1) He utu nui nga rauemi mata o te karaihe LGS, a kaore he pakaruhanga ki te whakakapi i te gallium ki te konumohe he iti ake te utu; (2) He iti te whakarea EO o LGS. Hei whakaiti i te ngaohiko whakahaere i runga i te kaupapa o te whakarite i te nui o te aperture, me nui ake te roa o te karaihe o te taputapu, ehara i te mea ka piki ake te utu engari ka piki ake te ngaro o te whakauru.
