Lanthanum gallium silicate (La₃Ga₅SiO₁₄, LGS) kristaro ndeye tripartite crystal system, point group 32, space group P₃₂₁ (Nhamba.150). LGS ine zvakawanda zvinokonzeresa senge piezoelectric, electro-optical, optical rotation, uye inogona zvakare kushandiswa senge laser material kuburikidza nedoping. Muna 1982, Kaminskyet al. yakashuma kukura kwedoped LGS makristasi. Muna 2000, makristasi eLGS ane dhayamita ye3 inch uye kureba kwe90 mm akagadzirwa naUda naBuzanov.

LGS crystal yakanakisa piezoelectric zvinhu nekucheka mhando ye zero tembiricha coefficient. Asi zvakasiyana nepiezoelectric application, electro-optic Q-switching application inoda yakakwira mhando yekristaro. Muna 2003, Konget al. yakabudirira kukura LGS makristasi pasina pachena macroscopic defects nekushandisa Czochralski nzira, uye akawana kuti kukura kwemhepo kunokanganisa ruvara rwemakristasi. Vakawana makristasi asina ruvara uye grey LGS uye vakaita LGS muEO Q-switch ine saizi ye6.12 mm × 6.12 mm × 40.3 mm. Muna 2015, rimwe boka rekutsvagisa muShandong University rakabudirira kukura makristasi eLGS ane dhayamita 50 ~ 55 mm, kureba 95 mm, uye uremu 1100 g pasina hurema huri pachena.

Muna 2003, boka rekutsvagisa rataurwa pamusoro muShandong University rakarega laser beam ichipfuura nepakati peGLS crystal kaviri ndokuisa quarter wave plate kurwisa iyo optical rotation effect, nokudaro yakaziva kushandiswa kweiyo optical rotation effect yeLGS crystal. Yekutanga LGS EO Q-switch ipapo yakagadzirwa uye yakabudirira kuiswa mu laser system.

Muna 2012, Wang et al. yakagadzira LGS electro-optic Q-switch ine saizi ye7 mm × 7 mm × 45 mm, uye yakaona kubuda kwe2.09 μm pulsed laser beam (520 mJ) mune flash- rambi rakapomba Cr, Tm, Ho: YAG laser system. . Muna 2013, 2.79 μm pulsed laser beam (216 mJ) yakabuda yakawanikwa mune flash-lambi pumped Cr, Er: YSGG laser, ine pulse width 14.36 ns. Muna 2016, Maet al. yakashandisa 5 mm × 5 mm × 25 mm LGS EO Q switch muNd:LuVO4 laser system, kuona kudzokorora mwero we200 kHz, inova mwero wepamusoro wekudzokorora weLGS EO Q-switched laser system yakataurwa pachena parizvino.

SeEO Q-switching material, LGS crystal ine yakanaka kugadzikana kwekushisa uye yakakwirira kukuvara kwechikumbaridzo, uye inogona kushanda nepamusoro yekudzokorora frequency. Zvisinei, kune matambudziko akawanda: (1) The raw material yeLGS crystal inodhura, uye hapana kubudirira mukutsiva gallium nealuminium iyo inodhura; (2) EO coefficient yeLGS idiki. Kuti uderedze magetsi ekushanda pachigadziro chekuvimbisa kukwana kwakakwana, kureba kwekristaro kwechigadzirwa kunoda kuwedzerwa mutsara, izvo zvisingango wedzera mutengo chete asiwo zvinowedzera kurasikirwa kwekuisa.
