Ngemva konyaka wokusebenza kanzima, sesikhulileIkristalu ye-Gasengekhwalithi enhle kakhulu ngempumelelo.
Ubuchwepheshe bethu buyakwazi ukuhlinzekaI-GaSeikristalu enembobo enkulu kanye nogqinsi oluncane.
Gallium Selenide (I-GaSe) ikristalu eyodwa ye-optical non-linear, ehlanganisa i-coefficient enkulu engeyona umugqa, umkhawulo womonakalo ophezulu kanye nobubanzi obubanzi bokukhanyela.Kuyinto efanelekile kakhulu ku-SHG maphakathi ne-IR.Izici zokuphindaphinda kabili kweI-GaSezifundwe kububanzi be-wavelength phakathi kuka-6.0 µm no-12.0 µm.I-GaSeisetshenziswe ngempumelelo ku-SHG ye-CO2 laser (kufika ku-9% ukuguqulwa);ye-SHG ye-pulsed CO, CO2 kanye nekhemikhali ye-DF-laser (l = 2.36 µm) imisebe;ukuguqulwa kwemisebe ye-laser ye-CO ne-CO2 ibe uhla olubonakalayo;ukukhiqizwa kwe-infrared pulses ngokusebenzisa umehluko wokuhlanganisa imvamisa ye-Neodymium kanye ne-infrared dye laser noma (F-)-centre laser pulses;Ukukhiqiza ukukhanya kwe-OPG phakathi kuka-3.5–18 µm;ukukhiqizwa kwemisebe ye-terahertz (T-rays).Akunakwenzeka ukusika amakristalu ama-engeli athile ahambisana nesigaba ngenxa yesakhiwo sezinto ezibonakalayo (i-cleave along (001) indiza) ekhawulela izindawo zohlelo lokusebenza.
