    ʻO Gallium Selenide (GaSe) non-linear optical single crystal, e hui pū ana i kahi coefficient non-linear nui, kahi paepae pōʻino kiʻekiʻe a me kahi ākea ākea ākea.He mea kūpono loa ʻo GaSe no SHG ma waena o IR.DIEN TECHhāʻawi i ke aniani GaSe me ka nui kūʻokoʻa a me ke ʻano kiʻekiʻe.

    Ua aʻo ʻia nā waiwai pālua pinepine o GaSe ma ka laulā nalu ma waena o 6.0 µm a me 12.0 µm.Ua hoʻohana maikaʻi ʻia ʻo GaSe no ka SHG kūpono o CO2 laser (a hiki i ka 9% hoʻololi);no ka SHG o pulsed CO, CO2 a me kemika DF-laser (l = 2.36 µm) radiation;ka hoʻohuli ʻana o CO a me CO2 laser radiation i ka laulā ʻike ʻia;hana ʻia nā puʻupuʻu infrared ma o ka hui ʻana o ka neodymium a me ka laser dye infrared a i ʻole (F-) -centre laser pulses;Hoʻokumu māmā OPG i loko o 3.5–18 µm;terahertz (T-rays) hoʻolaulaula.ʻAʻole hiki ke ʻoki i nā kristal no kekahi mau ʻāpana like ʻole ma muli o ke ʻano o ka mea (e hoʻokaʻawale i ka mokulele (001)) e kaupalena ana i nā wahi o nā noi.
    ʻO ka GaSe kahi aniani palupalu loa.No ka hana ʻana i ke aniani me ka mānoanoa kikoʻī, lawe mākou i ka mānoanoa e hoʻomaka ana i ka blank, No ka laʻana, 1-2 mm mānoanoa a laila hoʻomaka e wehe i ka papa ma ka papa e hoʻāʻo ana e hoʻokokoke i ka mānoanoa kauoha ʻoiai e mālama ana i ka maʻalahi o ka ʻili a me ka palahalaha.Eia nō naʻe, no ka mānoanoa e pili ana i ka 0.2-0.3 mm a i ʻole ka liʻiliʻi o ka pā GaSe e kūlou maʻalahi a loaʻa iā mākou ka ʻili curved ma kahi o kahi pālahalaha.
    No laila mākou e noho maʻamau ma 0.2 mm mānoanoa no 10x10 mm aniani i kau ʻia i loko o ka dia.1 '' paʻa me CA wehe ʻana.9-9.5 mm.
    I kekahi manawa ʻae mākou i nā kauoha no nā kristal 0.1 mm, akā naʻe, ʻaʻole mākou e hōʻoia i ka palahalaha maikaʻi no nā kristal lahilahi.
    Nā noi o nā kristal GaSe:
    • THz (T-kukui) hana hoʻokalakala;
    • Laulā THz:0.1-4 THz;
    • SHG kūpono o CO 2 laser (hiki i ka 9% hoʻololi);
    • No ka SHG o pulsed CO, CO2 a me DF-laser kemika (l = 2.36 mkm) radiation;
    • Ka hoʻohuli ʻana o CO a me CO2 laser radiation i ka laulā ʻike ʻia;hana ʻia nā puʻupuʻu infrared ma o ka hui ʻana o ka neodymium a me ka laser dye infrared a i ʻole (F-) -centre laser pulses;
    • OPG hana kukui i loko o 3.5 - 18 mkm.
    SHG i ka waena-IR (CO2, CO, kemika DF-laser etc.)
    ka hoʻohuli ʻana o ka pāhawewe laser IR i ka laulā ʻike ʻia
    Hanana parametric i loko o 3 – 20 µm
    ʻO Terahertz THz Generation (Hāʻawi ʻo Del Mar Photonics i nā ʻano kristal no ka hanauna THz, me ZnTe, GaP, LiNbO3 a me nā mea ʻē aʻe)
    ʻO nā waiwai nui o nā kristal GaSe:
    Laulā mālohi, µm 0.62 - 20
    Hui lae 6m2
    Nā ʻāpana lattice a = 3.74, c = 15.89 Å
    Māmā, g/cm3 5.03
    Mohs paakiki 2
    Nā kuhikuhina refractive:
    ma 5.3 µm no= 2.7233, ne= 2.3966
    ma 10.6 µm no= 2.6975, ne= 2.3745
    Koefficient laina ole, pm/V d22 = 54
    Holo i ka 4.1° ma 5.3 µm
    ʻO ka paepae hōʻino ʻino, MW/cm2 28 (9.3 µm, 150 ns);0.5 (10.6 µm, ma ke ʻano CW);30 (1.064 µm, 10 ns)
