    AGS yog pob tshab los ntawm 0.50 txog 13.2 µm. Txawm hais tias nws cov kab hluav taws xob tsis sib txuas yog qhov qis tshaj plaws ntawm cov tau hais hauv infrared muaju, siab luv luv wavelength transparency edging ntawm 550 nm yog tau siv hauv OPOs uas tau nqus los ntawm Nd: YAG laser; nyob rau hauv qhov sib txawv ntau zaus sib xyaw ua ke nrog diode, Ti: Sapphire, Nd: YAG thiab IR dye lasers npog 3–12 µm ntau; hauv kev ncaj qha infrared countermeasure, thiab rau SHG ntawm CO2 laser. Nyias AgGaS2 (AGS) siv lead ua cov paib yog nrov rau ultrashort mem tes tiam hauv nruab nrab IR ntau yam los ntawm qhov txawv zaus tiam ua haujlwm NIR wavelength pulses.
    Daim ntaub ntawv:
    • Kev tsim hluav taws xob zaum ob ntawm CO thiab CO2 - lasers
    • Cov kws txawj kho qhov muag
    • Lub tshuab hluav taws xob sib txawv kom txog nruab nrab thaj tsam infrared txog 12 mkm.
    • Kev tso ua ke ntau hauv nruab nrab IR thaj tsam ntawm 4.0 txog 18.3 µm
    • Cov khoom sib tw tau ruaj khov lub xeev lasers (OPO pumped los ntawm Nd: YAG thiab lwm tus lasers ua haujlwm nyob rau thaj tsam 1200 txog 10000 nm nrog kev ua haujlwm 0.1 mus rau 10%)
    • Optical nqaim-band lim nyob hauv thaj av ze ntawm isotropic point (0.4974 m ntawm 300 ° K), kis tau tus kab mob tig tau los ntawm qhov ntsuas kub hloov.
    • Kev hloov pauv ntawm CO2 laser duab ci rau hauv ze-IR lossis thaj chaw pom los ntawm kev siv / lossis siv Nd: YAG, ruby ​​lossis zas lasers nrog kev ua tau zoo txog 30%

    Qhov ntev:

    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.
