    Ividiyo

    I-Gallium Selenide (GaSe) i-crystal eyodwa engahambisani nomugqa, ehlanganisa i-coefficient enkulu engekho emgqeni, umkhawulo omkhulu wokulimala kanye nohlu olubanzi lokubonisa okusobala. Kuyinto efanelekile kakhulu ye-SHG maphakathi ne-IR. Izici eziphindwe kabili zeGaSe zifundwe ebangeni lobude obuphakathi kuka-6.0 µm no-12.0 µm. I-GaSe isetshenziselwe ngempumelelo i-SHG esebenza kahle ye-CO2 laser (kufika ku-9% ukuguqulwa); kwe-SHG ye-pulsed CO, i-CO2 kanye ne-chemical DF-laser (l = 2.36 µm); ukuguqulwa kwemisebe ye-CO ne-CO2 laser kububanzi obubonakalayo; ukukhiqizwa kwe-infrared pulses ngokuhluka kokuvama kokuhlanganiswa kwe-Neodymium ne-infrared laser laser noma (F -) - isikhungo se-laser pulses; Ukukhiqizwa kokukhanya kwe-OPG ngaphakathi kuka-3.5-18 µm; terahertz (T-ray) ukwenziwa kwemisebe. Akunakwenzeka ukusika amakristalu ezinhlangothini ezithile ezihambisana nama-engeli ngenxa yesakhiwo (ukunamathela endizeni (001)) esikhawulela izindawo zezicelo.
    I-GaSe iyikristalu elithambile futhi eligqinsiwe. Ekhiqizweni kristall ngogqinsi olucacisiwe sithatha ukujiya okuqala kungenalutho, Isibonelo, u-1-2 mm ubukhulu bese siqala ukususa ungqimba ngongqimba sizama ukusondela kubukhulu obuyaliwe ngenkathi sigcina ubushelelezi bendawo nobushelelezi. Kodwa-ke, ngobukhulu obucishe bube ngu-0.2-0.3 mm noma ngaphansi kwepuleti le-GaSe ligobeka kalula futhi sithola indawo egobile esikhundleni sefulethi elilodwa.
    Ngakho-ke imvamisa sihlala ku-0.2 mm ubukhulu be-10x10 mm crystal efakwe ku-dia.1 `` ophethe i-CA yokuvulwa kwe-dia. 9-9.5 mm.
    Kwesinye isikhathi samukela ama-oda wamakristalu ayi-0.1 mm, noma kunjalo, asiqinisekisi ukuthamba okuhle kwamakristalu amancane kangaka.
    Izicelo:
    • Ukukhiqizwa kwemisebe ye-THz (T-rays) radiation
    Ibanga le-THz: 0.1-4 THz ;
    • I-SHG esebenza kahle ye-CO 2 laser (kufika ku-9% ukuguqulwa);
    • Nge-SHG ye-pulsed CO, i-CO2 ne-chemical DF-laser (l = 2.36 mkm) imisebe;
    • Ukuguqulwa kwemisebe yelaser ye-CO ne-CO2 kububanzi obubonakalayo; ukukhiqizwa kwe-infrared pulses ngokuhluka kokuvama kokuhlanganiswa kwe-Neodymium ne-infrared laser laser noma (F -) - isikhungo se-laser pulses;
    • Isizukulwane sokukhanya se-OPG ngaphakathi kuka-3.5 - 18 mkm.
    I-SHG maphakathi ne-IR (CO2, CO, chemical DF-laser njll.)
    ukuguqulwa kwemisebe ye-IR laser kububanzi obubonakalayo
    Isizukulwane sepharamitha ngaphakathi kwe-3 - 20 µm
    Isizukulwane seTerahertz THz (iDel Mar Photonics inikezela ngamakristalu ahlukahlukene wesizukulwane se-THZ, kufaka phakathi iZnTe, GaP, LiNbO3 nabanye)
    Izakhiwo Eziyinhloko:
    Ububanzi bokubonisa ngale, 0.m 0.62 - 20
    Iqembu lokukhomba 6m2
    Amapharamitha we-Lattice a = 3.74, c = 15.89 Å
    Ubuningi, g / cm3 5.03
    Ubulukhuni be-Mohs 2
    Izinkomba zokubonisa:
    ngo-5.3 nom no = 2.7233, ne = 2.3966
    ngo-10.6 nom no = 2.6975, ne = 2.3745
    Coefficient engekho emgqeni, pm / V d22 = 54
    Suka ku-4.1 ° ku-5.3 µm
    Umbundu wokulimala okubonakalayo, MW / cm2 28 (9.3 ,m, 150 ns); 0.5 (10.6 µm, kumodi ye-CW); 30 (1.064 64m, 10 ns)
