Amakristalu e-BGGSe(BaGa2GeSe6).

I-crystal ye-BaGa2GeSe6 inomkhawulo ophezulu wokulimala optical (110 MW/cm2), ububanzi be-spectral transparency range (kusuka ku-0.5 kuya ku-18 μm) kanye nokungaqondile okuphezulu (d11 = 66 ± 15 pm/V) , okwenza le crystal ikhange kakhulu ukuguqulwa kwemvamisa kwemisebe ye-laser ibe (noma ngaphakathi) kwebanga eliphakathi kwe-IR.Kwafakazelwa mhlawumbe iyikristalu esebenza kahle kakhulu esizukulwaneni sesibili se-harmonic semisebe ye-CO- ne-CO2-laser.Kutholwe ukuthi ukuguqulwa kwe-broadband yezigaba ezimbili ze-multi-lineCO-laser radiation kule crystal kungenzeka ngaphakathi kwebanga le-wavelength elingu-2.5-9.0 μm ngokusebenza kahle okuphezulu kunamakristalu e-ZnGeP2 ne-AgGaSe2.
Amakristalu e-BaGa2GeSe6 asetshenziselwa ukuguqulwa kwefrikhwensi ye-optical nonlinear ebangeni lawo lokubonisa ngale.Ubude begagasi lapho ukusebenza kahle okukhulu kokuguqulwa kungatholwa khona kanye nobubanzi bokushuna bokukhiqiza umehluko wemvamisa buyatholakala.Kuboniswa ukuthi kunezinhlanganisela ze-wavelength lapho i-coefficient engasebenzi kahle ye-nonlinearity ihluka kancane kuphela kubhendi yefrikhwensi ebanzi.
