    Gallium Selenide (GaSe) hal muraayad oo toos ah oo aan toos ahayn, oo isku daraya isku dheelitirnaan aan toos ahayn, qaddar dhaawac weyn iyo baaxad ballaadhan. Waa qalab aad ugu habboon SHG bartamaha IR. Waxyaabaha soo noqnoqda ee GaSe ayaa lagu bartay baaxadda dhererka inta u dhexeysa 6.0 µm iyo 12.0 µm. GaSe waxaa si guul leh loogu adeegsaday SHG wax ku ool ah ee CO2 laser (illaa 9% beddelaad); loogu talagalay SHG ee pulsed CO, CO2 iyo kiimikada DF-laser (l = 2.36 µm) shucaaca; u-rogidda shucaaca laser-ka ee CO iyo CO2 ee u dhexeeya kala-duwanaanta muuqata; soosaarka garaaca 'infrared pulses Generation' iyadoo la adeegsanayo isku darka kala duwanaanta soo noqnoqodka ee Neodymium iyo laser dheeh infrared ama (F -) - usha laysarka dhexe; Soosaarka iftiinka OPG gudaha 3.5-18 µm; dhalista shucaaca ee terahertz (T-rays). Waa wax aan suurta gal ahayn in loo gooyo kristantarrada xaglo waji ah oo iswaafajinaya sababtoo ah qaab dhismeedka maadada (ku xir (001) diyaarad) xaddidaya aagagga codsiyada.
    GaSe waa kareem aad u jilicsan oo lakab ah. Soosaarida macdanta leh dhumucda cayiman waxaan qaadaneynaa bilaa dhumuc bilow ah, Tusaale ahaan, 1-2 mm qaro weyn kadibna bilaw inaad ka saarto lakabka lakab isku dayaya inuu u dhawaado dhumucda la amro iyadoo la ilaalinayo dusha sare ee dusha sare iyo fidsan. Si kastaba ha noqotee, dhumucda qiyaastii 0.2-0.3 mm ama ka yar saxanka GaSe ayaa si fudud u foorarsanaya waxaanan helnaa dusha sare oo qalooca halkii aan ka heli lahayn mid flat
    Markaa waxaan badanaa joognaa dhumucda 0.2 mm ee 10x10 mm crystal oo lagu rakibay dia. 1 '' haysta oo leh furitaanka furitaanka CA. 9-9.5 mm.
    Mararka qaarkood waxaan aqbalnaa amarrada 0.1 mm kiristaalo, hase yeeshe, dammaanad kama qaadaynno fidnaan wanaagsan oo loogu talagalay kiristaalo dhuuban.
    Codsiyada:
    • Soosaarka shucaaca THz (T-rays) ;
    • THz Range : 0.1-4 THz ;
    • SHG hufan oo ah laser 2 CO (illaa 9% beddelaad);
    • Loogu talagalay SHG of pulsed CO, CO2 iyo kiimikada DF-laser (l = 2.36 mkm) shucaaca;
    • U-rogidda shucaaca laser-ka ee CO iyo CO2 noocyada la arki karo; soosaarka garaaca 'infrared pulses Generation' iyadoo la adeegsanayo isku darka kala duwanaanta soo noqnoqodka ee Neodymium iyo laser dheeh infrared ama (F -) - usha laysarka dhexe;
    • Soosaarida iftiinka OPG-ga gudaha 3.5 - 18 mkm
