AgGaS2 - Ntabwo ari umurongo wa Optical Infrared Crystal
Ibisobanuro ku bicuruzwa
Isahani ntoya ya AgGaS2 (AGS) ikariso irazwi cyane kubyara ultrashort pulse kubyara hagati ya IR hagati yumurongo utandukanye ukoresha NIR yumurambararo.
Porogaramu
Igisekuru cya kabiri guhuza kuri CO na CO2 - laseri
Os Oscilator optique
Generator Itanga amashanyarazi atandukanye kugeza uturere twa infragre hagati ya mkm 12.
Kuvanga inshuro nyinshi mukarere ka IR hagati kuva 4.0 kugeza 18.3 µm
Las Guhindura ibyuma bikomeye bya leta (OPO yavomwe na Nd: YAG hamwe nizindi lazeri zikorera mukarere ka 1200 kugeza 10000 nm mukarere 0.1 kugeza 10%)
Akayunguruzo ka optique gafite akayunguruzo mu karere hafi ya isotropic point (0.4974 m kuri 300 ° K), umurongo wohereza uhuza ubushyuhe butandukanye
● Hejuru-guhindura ishusho yimirasire ya CO2 hafi ya IR cyangwa mukarere kagaragara ukoresheje / cyangwa ukoresheje Nd: YAG, ruby cyangwa irangi ryirangi rifite ubushobozi bugera kuri 30%
Ibiranga
Kwanduza muri mm 0,25-5.0, nta kwinjiza muri mm 2-3
● Amashanyarazi menshi
