Enye impahla efaneleka kakhulu i-SHG maphakathi ne-IR i-Gallium Selenide (GaSe) ikristalu eyodwa yokubona engaqondile.Ama-Crsytals e-GaSe ahlanganisa i-coefficient enkulu engenamugqa, i-threshold yomonakalo omkhulu kanye nohla olubanzi lokubonisa ngale.Izakhiwo zokuphindaphinda imvamisa ye-GaSe zacwaningwa ebangeni le-wavelength phakathi kuka-6.0 µm no-12.0 µm
Amakristalu e-GaSe anobulukhuni be-Mohs obuphansi kakhulu, okwenza i-GaSe ibe ntekenteke kakhulu futhi aqede amathuba okusebenzisa ukwelashwa ngomshini noma okokunamathela.
I-GaSe ifaneleka kakhulu ukusetshenziswa kwe-electronic kanye ne-optical.
