GaSe Crystal

Gallium Selenide (GaSe) idafite umurongo wa optique imwe ya kristu, ihuza coefficente nini itari umurongo, ibyangiritse cyane kandi byaragutse.GaSe nigikoresho gikwiye cyane kuri SHG hagati ya IR.DIEC TECHtanga GaSe kristu ifite ubunini bunini budasanzwe kandi bufite ireme.

Imiterere-yikubye kabiri ya GaSe yizwe muburebure bwumurongo uri hagati ya 6.0 µm na 12.0 µm.GaSe yakoreshejwe neza muburyo bwiza SHG bwa CO2 laser (kugeza 9% ihinduka);kuri SHG ya CO, CO2 na chimique DF-laser (l = 2,36 µm);kuzamura imirasire ya CO na CO2 ya laser mu ntera igaragara;infrared pulses kubyara binyuze mumwanya utandukanye wo kuvanga Neodymium na infrared dye laser cyangwa (F -) - hagati ya laser pulses;OPG itanga urumuri muri 3.5–18 µm;terahertz (T-imirasire) kubyara imirasire.Ntibishoboka guca kristu kumurongo runaka uhuza inguni kuberako imiterere yibintu (ikomatanya (001) indege) igabanya aho wasabye.
GaSe iroroshye cyane kandi ifite kristu.Kugirango tubyare umusaruro wa kirisiti hamwe nubunini bwihariye dufata umubyimba utangiye ubusa, Kurugero, mm 1-2 z'ubugari hanyuma tugatangira gukuramo ibice kumurongo ugerageza kwegera kubyimbye byateganijwe mugihe ugumye neza neza kandi neza.Nyamara, kubyimbye hafi ya 0.2-0.3 mm cyangwa munsi ya plaque ya GaSe irunama byoroshye kandi tubona ubuso bugoramye aho kuba bumwe.
Mubisanzwe rero tuguma kuri 0.2 mm z'ubugari bwa 10x10 mm ya kirisiti yashizwe muri dia.1 '' ufite hamwe na CA ifungura dia.9-9.5 mm.
Rimwe na rimwe, twemeye gutumiza 0.1 mm kristu, ariko, ntabwo dushimangira uburinganire bwiza kuri kristu yoroheje.
Porogaramu ya GaSe kristu:
• Imirasire ya THz (T-imirasire) ；
• Urutonde rwa THz ： 0.1-4 THz ；
• SHG ikora neza ya CO 2 laser (kugeza 9% ihinduka);
• Kuri SHG ya CO, CO2 na chimique DF-laser (l = 2,36 mkm);
• Kuzamura imirasire ya CO na CO2 murwego rugaragara;infrared pulses kubyara binyuze mumwanya utandukanye wo kuvanga Neodymium na infrared dye laser cyangwa (F -) - hagati ya laser pulses;
• OPG itanga urumuri muri mkm 3,5 - 18.
SHG hagati ya IR (CO2, CO, imiti DF-laser nibindi)
upconversion ya IR laser imirasire murwego rugaragara
Igisekuru cya Parametric muri 3 - 20 µm
Ibyingenzi byingenzi bya kristu ya GaSe:
Urwego rwo gukorera mu mucyo, µm 0,62 - 20
Itsinda ry'ingingo 6m2
Ibipimo bya latike a = 3.74, c = 15.89 Å
Ubucucike, g / cm3 5.03
Mohs gukomera 2
Ibipimo byerekana:
kuri 5.3 µm no = 2.7233, ne = 2.3966
kuri 10.6 µm no = 2.6975, ne = 2.3745
Coefficient itari umurongo, pm / V d22 = 54
Genda kuri 4.1 ° kuri 5.3 µm
Ibyangiritse byangiritse, MW / cm2 28 (9.3 µm, 150 ns);0.5 (10,6 µm, muburyo bwa CW);30 (1.064 µm, 10 ns)
