    Ividiyo

    I-AGS isobala kusuka ku-0.50 kuye ku-13.2 µm. Yize i-coefficient yayo ye-nonlinear optical ingaphansi kunawo wonke phakathi kwamakristalu we-infrared ashiwo, ukukhanya okuvelele okuphezulu kwe-wavelength ku-550 nm kuyasetshenziswa kuma-OPO akhishwe yi-Nd: YAG laser; ekuhlolweni okuhlukahlukene kokuvama kokuvama nge-diode, Ti: Sapphire, Nd: YAG kanye ne-IR dae lasers ehlanganisa u-3-12 µm ububanzi; ezinhlelweni zokulwa ngqo ze-infrared, naku-SHG ye-CO2 laser. Amapuleti e-crystal a-Thin AgGaS2 (AGS) athandwa kakhulu ekukhiqizweni kwe-ultrashort pulse maphakathi no-IR range ngomehluko wemvamisa yokukhiqiza esebenzisa ukuqhuma kwamaza we-NIR.
    Izicelo:
    • Isizukulwane sama-harmoniki wesibili ku-CO naku-CO2 - ama-lasers
    • I-oscilator ye-parametric ebonakalayo
    • I-generator ehlukile yemvamisa eya ezifundeni eziphakathi kwe-infrared kuze kufike ku-12 mkm.
    • Ukuxubeka kwemvamisa esifundeni esiphakathi se-IR kusuka ku-4.0 kuye ku-18.3 µm
    Ama-lasers state solid tuneable (i-OPO ikhishwe ngu-Nd: YAG namanye ama-lasers asebenza esifundeni se-1200 kuya ku-10000 nm ngokusebenza kahle kwe-0.1 kuye ku-10%)
    Izihlungi ze-Optical-band-optical esifundeni esiseduze nephoyinti le-isotropic (0.4974 m ku-300 ° K), ibhendi yokudlulisa elungiselelwa ukushintshashintsha kwezinga lokushisa
    • Ukuguqulwa okuphezulu kwesithombe semisebe ye-laser sibe yi-IR eseduze noma ebonakalayo ngokusebenzisa / noma ukusetshenziswa kwe-Nd: YAG, irubi noma idayi lasers ngokusebenza kahle kuze kufike ku-30%

    Ubukhulu:

    Izingxenye ezijwayelekile zesiphambano ziyi-8x 8mm, 5 x 5mm, ibanga lobude be-Crystal kusuka ku-1 kuye ku-30 ​​mm. Amasayizi wangokwezifiso ayatholakala uma ucelwa.
