Iikristale ezingezizo-Icandelo lesi-2

Iindlela zokukhula ezibandakanya ezithe tye kunye nezithe nkqo, ezi zixhobo (ZnGeP2, AgGaS2, AgGaSe2, GaSe, KTA, KTP, BIBO, LBO, BBO) ziyafumaneka ngobungakanani obunikiweyo obuqhelekileyo kunye nokuqhelaniswa.Ezinye zazo, ezineepropati ze-coefficient enkulu engabonakaliyo kunye nemilinganiselo ekhethekileyo esiyinikezile isetyenziswa ngokubanzi kwi-SHG eqhelekileyo, i-THG kunye ne-Mid-infrared OPO, iinkqubo ze-OPA, njl.

Iikristale ze-AGGS(AgGaGeS4).

Ikristale ye-AgGaGeS4 sesinye sekristale eyomeleleyo yesisombululo esinamandla amakhulu kakhulu phakathi kweekristale ezikhulayo ezingenamda.Izuza i-coefficient ephezulu ye-optical nonlinear (d31 = 15pm / V), uluhlu olubanzi lokudluliselwa (0.5-11.5um) kunye ne-coefficient ephantsi yokufunxa (0.05cm-1 kwi-1064nm).
IiCrystals ze-AGGSe(AgGaGe5Se12).

I-AgGaGe5Se12 yikristale entsha ethembisayo engabonakaliyo yokutshintsha rhoqo i-1um ye-laser yesimo esiqinileyo ukuya kuluhlu oluphakathi lwe-infrared (2-12mum).
BIBO Crystal

I-BiB3O6 (BIBO) yikristale yamehlo esanda kuphuhliswa.Ine-coefficient enkulu esebenzayo engasebenziyo, umda womonakalo omkhulu kunye nokungangenisi malunga nokufuma.I-coefficient yayo engabonakaliyo yi-3.5 - 4 ngamaxesha aphezulu kune-LBO, i-1.5 -2 ngamaxesha aphezulu kune-BBO.Yikristale ethembisayo ephindwe kabini ukuvelisa i-laser eluhlaza.
Ikristale yeBBO

I-BBO yikristale entsha ye-ultraviolet frequency ephindwe kabini.Yikristale engalunganga ye-uniaxial, enesalathiso esiqhelekileyo se-refractive (hayi) esikhulu kune-extraordinary refractive index (ne).Zombini uhlobo lwe-I kunye nohlobo lwe-II oluhambelanayo lwesigaba lunokufikelelwa nge-angle tuning.
LBO Crystal

I-LBO (i-Lithium Triborate - i-LiB3O5) ngoku yeyona nto isetyenziswa kakhulu kwi-Second Harmonic Generation (SHG) ye-1064nm i-laser yamandla aphezulu (njengendawo ebambela i-KTP) kunye ne-Sum Frequency Generation (SFG) ye-1064nm yomthombo we-laser ukufezekisa ukukhanya kwe-UV kwi-355nm. .
KTA Crystal

I-Potassium Titanyle Arsenate (i-KTiOAsO4), okanye i-KTA crystal, yinto egqwesileyo ye-crystal optical egqwesileyo ye-Optical Parametric Oscillation (OPO) yesicelo.Ine-non-linear optical kunye ne-electro-optical coefficients engcono, yanciphisa kakhulu ukufunxa kwindawo ye-2.0-5.0 µm, i-angular ebanzi kunye ne-bandwidth bandwidth, i-dielectric constants ephantsi.
