    Vhidhiyo

    Gallium Selenide (GaSe) isina-mutsara yakasarudzika sekristaro imwe chete, ichibatanidza yakakura isina-mitsara coefficient, yakanyanya kukuvara chikumbaridzo uye rakapamhamha pachena huwandu. Icho chinhu chakakodzera kwazvo cheSHG ​​pakati-IR. Iyo frequency-yakapetwa zvivakwa zveGaSe zvakadzidzwa muhurefu hwehurefu pakati pe6.0m uye 12.0 µm. GaSe rave rakabudirira kushandiswa kweiyo inoshanda SHG ye CO2 laser (inosvika 9% kutendeuka); ye SHG yepulpeded CO, CO2 uye kemikari DF-laser (l = 2.36 µm) radiation; kukwidziridzwa kwe CO uye CO2 laser radiation mune inoonekwa renji; infrared pulses chizvarwa kuburikidza nemusiyano frequency kusanganiswa kweNeodymium uye infrared dhayi laser kana (F -) - yepakati laser pulses; OPG mwenje chizvarwa mukati me3,5-18 µm; terahertz (T-ray) kugadzirwa kwemwaranzi. Hazvibviri kucheka makristasi echimwe chikamu chinowirirana nemakona nekuda kwechimiro chechimiro (kunamira pamwe (001) ndege) kudzikamisa nzvimbo dzekushandisa.
    GaSe yakanyorovera uye yakatsemuka kristaro. Zvekugadzirwa kwekristaro ine yakatarwa ukobvu tinotora mukobvu kutanga isina chinhu, Semuenzaniso, 1-2 mm gobvu uye tobva tatanga kubvisa dura neyakagadzika kuyedza kusvika kune yakarairwa ukobvu ichichengeta yakanaka pamusoro kutsetseka uye kumeso. Nekudaro, kune ukobvu ungangoita 0.2-0.3 mm kana kushoma GaSe ndiro inokombama nyore uye isu tinowana rakakomberedzwa pamusoro pane rakadzika rimwe.
    Saka isu tinowanzo gara pa 0.2 mm ukobvu we 10x10 mm kristaro yakaiswa mu dia. 1 `` mubati ane CA yekuvhura dia. 9-9.5 mm.
    Dzimwe nguva tinogamuchira maodha emakristani e0,1 mm, zvisinei, isu hativimbise kugona kwakanaka kwemakristasi matete.
    Mafomu:
    • THz (T-ray) kugadzirwa kwemwaranzi radiation
    • THZ Range: 0.1-4 THz ;
    • SHG inoshanda ye CO 2 laser (inosvika 9% kutendeuka);
    • Ye SHG ye pulsed CO, CO2 uye kemikari DF-laser (l = 2.36 mkm) radiation;
    • Upconversion ye CO uye CO2 laser radiation mune inoonekwa renji; infrared pulses chizvarwa kuburikidza nemusiyano frequency kusanganiswa kweNeodymium uye infrared dhayi laser kana (F -) - yepakati laser pulses;
    • OPG mwenje chizvarwa mukati me3,5 - 18 mkm.
    SHG iri pakati-IR (CO2, CO, kemikari DF-laser etc.)
    kukwirisa kwe IR laser radiation mune inoonekwa renji
    Parametric chizvarwa mukati me3 - 20 µm
    Terahertz THz chizvarwa (Del Mar Photonics inopa akasiyana makristasi echizvarwa cheTZ, kusanganisira ZnTe, GaP, LiNbO3 nevamwe)
