    Kev tsis

    Daim ntawv xeem

    Ho, Cr, Tm: YAG -yttrium aluminium garnet laser crystals doped nrog chromium, thulium thiab holmium ions los muab lasing ntawm 2.13 microns yog nrhiav ntau dua thiab ntau daim ntawv thov, tshwj xeeb hauv kev lag luam kho mob.Qhov txais tau qhov zoo ntawm cov khoom siv lead ua yog tias nws ntiav YAG los ua tus tswv tsev. YAG lub cev, cov khoom siv thermal thiab kho qhov muag tau paub zoo thiab nkag siab los ntawm txhua tus tsim qauv laser. Nws muaj cov ntawv thov dav hauv kev phais mob, kho hniav, kuaj ua pa, thiab lwm yam.
    Qhov zoo ntawm CTH: YAG:
    • Kev nqes hav siab tshaj
    • Raug txim los ntawm kev teeb nyem lossis diode
    • Ua haujlwm zoo nyob rau hauv chav tsev kub
    • Tau khiav lag luam nyob hauv lub qhov muag yuag-nyab xeeb
