    Gallium Selenide (GaSe) isina-linear optical single crystal, ichibatanidza yakakura isina-mutsara coefficient, yakakwirira kukuvara kwechikumbaridzo uye yakafara kujeka.GaSe chinhu chakanyatsokodzera zvinhu zveSHG mukati me-IR.DIEN TECHipa GaSe crystal ine yakasarudzika yakakura saizi uye yepamusoro mhando.

    Iyo frequency-yakapetwa kaviri zvivakwa zveGaSe zvakadzidzwa muwavelength renji pakati pe6.0 µm uye 12.0 µm.GaSe yakashandiswa zvakabudirira kune inoshanda SHG yeCO2 laser (kusvika ku9% kutendeuka);yeSHG ye pulsed CO, CO2 uye makemikari DF-laser (l = 2.36 µm) mwaranzi;kushandurwa kweCO uye CO2 laser mwaranzi mune inooneka renji;infrared pulses generation kuburikidza nemusiyano frequency kusanganiswa kweNeodymium uye infrared dhayi laser kana (F-)-centre laser pulses;OPG chiedza chizvarwa mukati 3.5–18 µm;terahertz (T-rays) kugadzirwa kwemwaranzi.Hazvigoneke kucheka makristasi kune mamwe nhanho inoenderana nemakona nekuda kwechimiro chemidziyo (kuchekerera pamwe (001) ndege) inodzikamisa nzvimbo dzekushandisa.
    GaSe yakapfava uye yakaturikidzana kristaro.Pakugadzirwa kwekristaro nehupamhi hwakatarwa tinotora mukobvu kutanga usina chinhu, Semuyenzaniso, 1-2 mm gobvu tobva tatanga kubvisa layer ne layer ichiedza kusvika kune yakaodha ukobvu uku uchichengeta kunaka kwepamusoro kutsetseka uye kupfava.Nekudaro, kune ukobvu hunosvika 0.2-0.3 mm kana kushoma GaSe ndiro inokotama zviri nyore uye tinowana yakakombama pachinzvimbo chefurati.
    Saka isu kazhinji kugara pa 0.2 mm ukobvu nokuda 10x10 mm crystal yakaiswa mukati dia.1'' mubati ane CA kuvhura dia.9-9.5 mm.
    Dzimwe nguva tinogashira maodha e0.1 mm makristasi, zvisinei, isu hativimbisi kutaridzika kwakanaka kwemakristasi akatetepa kudaro.
    Zvishandiso zveGaSe makristasi:
    • THz (T-rays) kugadzirwa kwemwaranzi;
    • THz Range: 0.1-4 THz;
    • Inoshanda SHG yeCO 2 laser (kusvika ku9% kutendeuka);
    • Kune SHG ye pulsed CO, CO2 uye makemikari DF-laser (l = 2.36 mkm) mwaranzi;
    • Kuvandudzwa kweCO uye CO2 laser radiation muhutano hunooneka;infrared pulses generation kuburikidza nemusiyano frequency kusanganiswa kweNeodymium uye infrared dhayi laser kana (F-)-centre laser pulses;
    • OPG chiedza chizvarwa mukati 3.5 - 18 mkm.
    SHG yepakati-IR (CO2, CO, makemikari DF-laser nezvimwewo)
    kushandurwa kweIR laser radiation mune inooneka renji
    Parametric chizvarwa mukati me3 - 20 µm
    Terahertz THz chizvarwa (Del Mar Photonics inopa akasiyana makristasi echizvarwa cheTHz, kusanganisira ZnTe, GaP, LiNbO3 nevamwe)
