    Izakhiwo eziyisisekelo

    I-crystal ye-BaGa2GeSe6 inomkhawulo omkhulu wokulimala okubonakalayo (i-110 MW / cm2), ibanga elibanzi lokubonisa okusobala (kusuka ku-0.5 kuye ku-18 μm) kanye ne-nonlinearity ephezulu (d11 = 66 ± 15 pm / V), okwenza le crystal ibukeke kakhulu ukuguqulwa kwemvamisa yemisebe ye-laser ibe (noma ngaphakathi) ebangeni eliphakathi ne-IR. Kubonakaliswe ukuthi kungenzeka ukuthi yi-crystal esebenza kahle kakhulu yesizukulwane sesibili se-harmonic seCO- ne CO2-laser radiation. Kutholakale ukuthi ukuguqulwa kwesigaba esinezigaba ezimbili zemvamisa yama-multi-lineCO-laser kule crystal kungenzeka ngaphakathi kwebanga lobubanzi obungu-2.5-9.0 μm ngokusebenza okuphezulu kunakuZnGeP2 naku-AgGaSe2 amakristalu.
    Amakristalu weBaGa2GeSe6 asetshenziselwa ukuguqulwa kwemvamisa ye-nonlinear optical in their transparency range. Ama-wavelengths lapho kutholakala khona ukusebenza okuphezulu kokuguqulwa nobubanzi bokushuna bokukhiqizwa kwemvamisa ehlukile. Kuyakhonjiswa ukuthi kunezinhlanganisela zamaza we-wave lapho i-coefficient esebenzayo ye-nonlinearity ihluka kancane ebhentshini lokuvama elibanzi.
