Makhalidwe aAOM acousto-optic modulator
Kupirira mkulu kuwala mphamvu
AOM acousto-optic modulator imatha kupirira mphamvu yamphamvu ya laser, kuwonetsetsa kuti ma laser amphamvu kwambiri amatha kudutsa bwino. Mu ulalo wa laser-fiber, thefiber acousto-optic modulatoratembenuza kuwala kosalekeza kukhala kuwala kwamphamvu. Chifukwa cha kuchepa kwa ntchito ya pulse optical, mphamvu zambiri za kuwala zimakhala mkati mwa kuwala kwa ziro. Kuwala koyambira koyamba komanso kuwala kwa ziro kunja kwa kristalo wa acousto-optic kumafalikira mwanjira yamitundu yosiyanasiyana ya Gaussian. Ngakhale kuti amakumana ndi zovuta zolekanitsa, mbali ya kuwala kwa kuwala kwa zero-order imawunjikana m'mphepete mwa optical fiber collimator ndipo sangathe kufalitsidwa kudzera mu fiber optical, potsirizira pake imayaka kupyolera mu optical fiber collimator. Mawonekedwe a diaphragm amayikidwa munjira ya kuwala kudzera pa chimango chapamwamba chapamwamba chazithunzi zisanu ndi chimodzi kuti aletse kufalikira kwa kuwala kosiyana pakati pa collimator, ndipo kuwala kwa zero kumatumizidwa ku nyumba kuti kuwala kwa zero kusakhale kotentha.
Nthawi yokwera mwachangu
Mu ulalo wa laser-fiber-yonse, nthawi yokwera mwachangu ya kugunda kwa kuwala kwa AOMacouste-optic modulatorimawonetsetsa kuti kugunda kwa siginecha yamakina kumatha kudutsa bwino kwambiri, ndikuletsa phokoso loyambira kulowa mu nthawi-domain acouste-optic shutter (time-domain pulse gate). Chofunika kwambiri kuti tikwaniritse nthawi yowonjezereka ya kuwala kwa kuwala kwagona pakuchepetsa nthawi yodutsa ya mafunde akupanga kupyolera mu kuwala. Njira zazikuluzikulu zimaphatikizapo kuchepetsa kukula kwa chiuno cha kuwala kwa zochitika kapena kugwiritsa ntchito zipangizo zothamanga kwambiri kuti apange makhiristo a acoust-optic.
Chithunzi 1 Kukwera kwanthawi ya kugunda kwamphamvu
Kugwiritsa ntchito mphamvu zochepa komanso kudalirika kwakukulu
Zoyendetsa ndege zili ndi zinthu zochepa, zovuta komanso malo ovuta, zomwe zimapangitsa kuti pakhale zofunikira kwambiri pakugwiritsa ntchito mphamvu komanso kudalirika kwa ma modulators a fiber AOM. The kuwala CHIKWANGWANIAOM moduleamatengera tangential wapadera acousto-optic crystal, amene ali mkulu acousto-optic khalidwe factor M2. Choncho, pansi pa zochitika zofanana za diffraction, mphamvu yoyendetsa galimoto yofunikira imakhala yochepa. Optical fiber acoust-optic modulator imatenga kamangidwe ka mphamvu kakang'ono kameneka, komwe sikungochepetsa kufunikira kwa kuyendetsa magetsi ndikupulumutsa zinthu zochepa zomwe zili mumlengalenga, komanso kutsitsa ma radiation amagetsi amagetsi oyendetsa ndikuchepetsa kutentha kwadongosolo. Malinga ndi zoletsedwa (zoletsedwa) zofunikira pakupanga zinthu zakuthambo, njira wamba yoyika kristalo ya optical fiber acousti-optic modulators imangotengera njira imodzi yomangira mphira ya silikoni. Kamodzi mphira silikoni kulephera, magawo luso la kristalo adzasintha pansi kugwedezeka mikhalidwe, amene sagwirizana ndi zofunika ndondomeko zinthu zakuthambo. Mu ulalo wa laser, kristalo wa optical fiber acoust-optic modulator imakhazikika pophatikiza kukonza kwamakina ndi mphira wa silicone. Mapangidwe opangira malo apamwamba ndi otsika pansi ndi ofanana momwe angathere, ndipo nthawi yomweyo, malo olumikizana pakati pa kristalo pamwamba ndi nyumba yoyikamo amakulitsidwa. Zili ndi ubwino wa mphamvu zowonongeka zowonongeka ndi kutentha kwapakati pa gawo la kutentha. Ma collimators ochiritsira amakonzedwa ndi kulumikiza mphira wa silicone. Pansi pa kutentha kwakukulu ndi kugwedezeka, amatha kusuntha, zomwe zimakhudza ntchito ya mankhwala. Mapangidwe amakina tsopano atengedwa kuti akonze makina opangira kuwala, omwe amathandizira kuti zinthu zizikhazikika komanso zimakwaniritsa zofunikira za zinthu zakuthambo.
