GaSe Crystal

Ko te Gallium Selenide (GaSe) he karaihe whatu kore-raina, he whakakotahi i te whakarea-kore-raina nui, he paepae kino nui me te whanui whanui.Ko te GaSe he rauemi tino pai mo te SHG i waenganui-IR.DIEN TECHwhakarato te karaihe GaSe me te rahi ahurei me te kounga teitei.

I akohia nga ahuatanga auau-rua o GaSe i te awhe roangaru i waenga i te 6.0 µm me te 12.0 µm.Kua pai te whakamahi a GaSe mo te SHG pai o te laser CO2 (tae atu ki te 9% te hurihanga);mo te SHG o te CO, CO2 me te matū DF-laser (l = 2.36 µm) radiation;te hurihanga o te CO me te CO2 laser radiation ki te awhe e kitea ana;whakangaonga puhoi pokarekare ma te whakakotahi i te auau rereke o te Neodymium me te taiaho waikano infrared ranei (F-)-pokapū taiaho pire;OPG hanga marama i roto i te 3.5–18 µm;terahertz (T-hihi) whakangao iraruke.Kare e taea te tapahi tioata mo etahi koki e rite ana ki te wahanga na te mea he hangahanga rawa (wehea ki te (001) rererangi) e whakatiki ana i nga waahi tono.
Ko te GaSe he karaihe ngohengohe me te paparanga.Mo te hanga karaihe me te matotoru kua tohua, ka tiimata te tiimata, hei tauira, 1-2 mm te matotoru katahi ka timata ki te tango paparanga ma ia paparanga e ngana ana ki te whakatata ki te matotoru ota me te pupuri i te maeneene me te papatahi o te mata.Heoi, mo te matotoru mo te 0.2-0.3 mm iti iho ranei te pereti GaSe ka ngawari te whakapiko ka whiwhi tatou i te mata kopiko engari i te papatahi.
No reira ka noho matou ki te 0.2 mm te matotoru mo te karaihe 10x10 mm e mau ana ki roto i te dia.1'' te pupuri me te CA whakatuwhera dia.9-9.5 mm.
I etahi wa ka whakaaehia e matou nga ota mo nga tioata 0.1 mm, heoi, kaore matou e kii he pai te papatahi mo nga tioata angiangi.
Nga tono mo nga tioata GaSe:
• THz (T-hihi) hanga iraruke;
• Awhe THz:0.1-4 THz;
• He pai te SHG o te laser CO 2 (tae atu ki te 9% te hurihanga);
• Mo te SHG o te CO, CO2 me te matū DF-laser (l = 2.36 mkm) radiation;
• Te huringa o te CO me te CO2 laser radiation ki te awhe e kitea ana;whakangaonga puhoi pokarekare ma te whakakotahi i te auau rereke o te Neodymium me te taiaho waikano infrared ranei (F-)-pokapū taiaho pire;
• OPG hanga marama i roto i te 3.5 - 18 mkm.
SHG i waenganui-IR (CO2, CO, matū DF-taiaho etc.)
