AgGaSe2 Muaju
AgGaSe2 muaju muaj cov npoo band ntawm 0.73 thiab 18 µm. Nws muaj txiaj ntsig kis tau zoo (0.9–16 µm) thiab qhov sib txawv theem muaj peev xwm ua tau zoo muaj peev xwm zoo rau OPO kev siv thaum nqus los ntawm ntau lub lasers sib txawv. Qhov sib xyaw tsis pub dhau 2.5–12 µm tau txais thaum nqus los ntawm Ho: YLF laser ntawm 2.05 µm; raws li qhov ua tau tsis zoo raws qib (NCPM) kev ua haujlwm tsis pub dhau 1.9-5.5 µm thaum tso kom deb ntawm 1.4-1.55 µm. AgGaSe2 (AgGaSe2) tau pom tias muaj lub zog siv zog ntau dua ob npaug rau cov duab hluav taws xob infrared CO2 lasers hluav taws xob.
Daim ntaub ntawv:
• Kev tsim hluav taws xob zaum ob ntawm CO thiab CO2 - lasers
• Optical parametric oscillator
• Lub tshuab hluav taws xob sib txawv kom txog nruab nrab thaj tsam infrared txog 18 um.
• Nquag sib xyaw ua ke hauv nruab nrab IR thaj av
Txheem hla ntu yog 8x 8mm, 5 x 5mm, Crystal ntev ntau los ntawm 1 txog 30 hli. Qhov ntau thiab tsawg kev cai kuj muaj nyob ntawm kev thov.
