    Gallium Selenide (GaSe) oo aan toos ahayn oo hal crystal ah, oo isku daraysa isku xidhe weyn oo aan toos ahayn, heer dhaawac sare ah iyo cadad ballaadhan.GaSe waa shay aad ugu habboon SHG bartamaha-IR.DIEN TECHBixi crystal GaSe leh cabbir weyn oo gaar ah iyo tayo sare leh.

    Sifooyinka soo noqnoqda-laba-laabma ee GaSe waxaa lagu daraaseeyay baaxadda hirarka dhererka inta u dhaxaysa 6.0 µm iyo 12.0 µm.GaSe ayaa si guul leh loogu isticmaalay SHG hufan ee CO2 laser (ilaa beddelka 9%);loogu talagalay SHG ee CO, CO2 iyo kiimikaad DF-laser (l = 2.36 µm) shucaaca;kor u kaca CO iyo CO2 shucaaca laser-ga ee baaxadda muuqata;abuurista garaaca wadnaha infrared iyada oo loo marayo kala duwanaansho isku-darka soo noqnoqda ee Neodymium iyo laser dheeha infrared ama (F-) -- -- - - - -- -beeraha laysarka;Jiilka iftiinka OPG gudaha 3.5-18 µm;Terahertz (T-rays) jiilka shucaaca.Suurtagal ma aha in la gooyo kirismaska ​​wejiga qaar ka mid ah xaglaha u dhigma sababta oo ah qaab-dhismeedka walxaha (ku xaji (001) diyaaradda) xaddidaya meelaha codsiyada.
    GaSe waa mid aad u jilicsan oo lakabyo leh.Soo saarista kareemka leh dhumuc gaar ah waxaan ku soo qaadnaa bilow bannaan oo dhumuc weyn leh, tusaale ahaan, dhumucdiisuna tahay 1-2 mm ka dibna waxaan bilownaa inaan lakabka ka saarno lakabka iyadoo la isku dayayo inaan u dhowaanno dhumucda la amray iyadoo la ilaalinayo simannaanta dusha sare iyo fidsanaanta.Si kastaba ha ahaatee, dhumucdiisuna waxay u dhaxaysaa 0.2-0.3 mm ama ka yar saxan GaSe si sahal ah u foorarsado oo waxaan helnaa oog qaloocan halkii mid siman.
    Markaa waxaan inta badan joognaa dhumucda 0.2 mm 10x10 mm crystal ku rakiban dia.1 '' haye leh CA furitaanka dia.9-9.5 mm.
    Mararka qaarkood waxaan aqbalnaa amarada 0.1mm crystals, si kastaba ha ahaatee, ma dammaanad qaadin flatness wanaagsan ee crystals dhuuban.
    Codsiyada kiristaalo GaSe:
    Jiilka shucaaca THz (T-rays);
    Qiyaasta THz: 0.1-4 TH;
    • SHG hufan ee CO 2 laser (ilaa 9% beddelaad);
    • Loogu talagalay SHG ee CO, CO2 iyo kiimikaad DF-laser (l = 2.36 mkm) shucaaca;
    • Isku-beddelka CO iyo CO2 shucaaca laser-ka oo loo beddelo baaxadda muuqata;abuurista garaaca wadnaha infrared iyada oo loo marayo kala duwanaansho isku-darka soo noqnoqda ee Neodymium iyo laser dheeha infrared ama (F-) -- -- - - - -- -beeraha laysarka;
    • Jiilka iftiinka OPG gudaha 3.5 - 18 mkm.
    SHG ee bartamaha IR (CO2, CO, DF-laser kiimikaad iwm.)
    U beddelka shucaaca laser-ka ee IR una beddelo baaxadda muuqata
    Jiilka Parametric gudaha 3 - 20 µm
