Emva konyaka wokusebenza nzima, siye sakhulaIkristale yeGasengomgangatho obalaseleyo ngempumelelo.
Itekhnoloji yethu iyakwazi ukubonelelaGaSeikristale ene-aperture enkulu kunye nobukhulu obuncinci.
Gallium SelenideGaSe) i-crystal optical single engabonakaliyo, idibanisa i-coefficient enkulu engekho-linear, i-threshold yomonakalo omkhulu kunye noluhlu olubanzi lokungafihli.Yimathiriyeli efanelekileyo kakhulu ye-SHG embindini we-IR.Iimpawu zokuphinda-phinda kabini zeGaSezaphononongwa kuluhlu lwamaza phakathi kwe-6.0 µm kunye ne-12.0 µm.GaSeisetyenziswe ngempumelelo kwi-SHG ye-CO2 laser (ukuya kwi-9% yokuguqulwa);ye-SHG ye-pulsed CO, CO2 kunye neekhemikhali ze-DF-laser (l = 2.36 µm) imitha;ukuguqulwa kwe-CO kunye ne-CO2 laser radiation kuluhlu olubonakalayo;ukuveliswa kwe-infrared pulses ngokusebenzisa umahluko ophindaphindiweyo wokuxuba i-Neodymium kunye ne-laser yedayi ye-infrared okanye (F-)-centre laser pulses;Isizukulwana sokukhanya se-OPG ngaphakathi kwe-3.5–18 µm;i-terahertz (i-T-reyi) ukuveliswa kwemitha.Akunakwenzeka ukusika iikristale kwii-angles ezithile ezihambelana nesigaba ngenxa yesakhiwo sezinto eziphathekayo (i-cleave along (001) indiza) ukunciphisa iindawo zezicelo.
