LGS Crystals

ʻO La3Ga5SiO14 crystal (LGS crystal) he mea nonlinear optical me ka paepae pōʻino kiʻekiʻe, coefficient electro-optical kiʻekiʻe a me ka hana electro-optical maikaʻi loa.No ka LGS crystal i ka trigonal system structure, li'ili'i thermal expansion coefficient, thermal expansion anisotropy o ka kristal, nāwaliwali ka mahana o ka wela wela ('oi aku ka maika'i ma mua o SiO2), me 'elua mau electro-optical coefficients e like me ka BBO. Nā Crystals.Paʻa nā coefficients electro-optic i kahi ākea o nā wela.Loaʻa i ka kristal nā waiwai mechanical maikaʻi, ʻaʻohe cleavage, ʻaʻohe deliquescence, kūpaʻa physicochemical a maikaʻi loa ka hana piha.Loaʻa i ka LGS crystal kahi kāʻei hoʻouna ākea, mai 242nm-3550nm ka nui o ka hoʻouna ʻana.Hiki ke hoʻohana ʻia no ka EO modulation a me EO Q-Switches.

He nui nā noi LGS crystal: ma waho aʻe o ka hopena piezoelectric, ka hopena rotation optical, ʻoi aku ka maikaʻi o kāna hana electro-optical effect, LGS Pockels Cells he kiʻekiʻe repetition frequency, ʻāpana ʻāpana nui, ākea pulse ākea, mana kiʻekiʻe, ultra -ʻo ka wela haʻahaʻa a me nā kūlana ʻē aʻe i kūpono no LGS crystal EO Q -switch.Ua noi mākou i ka coefficient EO o γ 11 e hana i nā pūnaewele LGS Pockels, a ua koho mākou i kona ʻano nui e hōʻemi i ka hapalua hawewe o LGS Electro-optical cell, hiki ke kūpono i ka electro-optical tuning o nā mea āpau. laser me ka mana kiʻekiʻe o ka hana hou ʻana.No ka laʻana, hiki ke hoʻohana ʻia i ka LD Nd: YVO4 solid-state laser pumped me ka mana awelika kiʻekiʻe a me ka ikehu ma luna o 100W, me ka helu kiʻekiʻe a hiki i 200KHZ, ka hopena kiʻekiʻe loa a hiki i 715w, ka laulā pulse a hiki i 46ns, ka hoʻomau. hoʻopuka a hiki i ka kokoke 10w, a ʻo ka paepae pōʻino optical he 9-10 mau manawa kiʻekiʻe ma mua o ka LiNbO3 crystal.ʻOi aku ka haʻahaʻa o ka 1/2 puʻe uila a me ka 1/4 hawewe nalu ma mua o ke anawaena like ʻo BBO Pockels Cells, a ʻoi aku ka haʻahaʻa o ke kumu kūʻai a me ka hui ʻana ma mua o ke anawaena like RTP Pockels Cells.Ke hoʻohālikelike ʻia me DKDP Pockels Cells, ʻaʻole lākou i hoʻonā a loaʻa ka paʻa wela maikaʻi.Hiki ke hoʻohana ʻia nā Kelepona Electro-optical LGS i nā wahi paʻakikī a hiki ke hana maikaʻi i nā noi like ʻole.
