Ukwakheka kohlelo lwei-modulator ye-acousto-optical
I-Acoustic Optical Modulator (i-AOM Modulator) okwamanje iyidivayisi yokuguquguquka esetshenziswa kakhulu ngaphandle kwe-laser cavity, engeyesistimu yobuchwepheshe bokuguquguquka kwangaphandle. Ithembele emiphumeleni ebonakalayo yokuxhumanisa i-acousto-optic ukuze kufezwe ukuvulwa/ukuvalwa kwemisebe, ukuqina kanye nokulawulwa kwemvamisa. Yindlela yokuguquguquka esetshenziswa kakhulu ekumakeni kwe-laser yezimboni, ukusika ngokunemba, indlela yokukhanya yocwaningo lwesayensi, kanye nemishini ye-radar ye-laser enamandla amancane naphakathi.
Ukwakheka kwesistimu,
Okupheleleukuguqulwa kwe-acousto-opticuhlelo luqukethe amayunithi amahlanu ayinhloko: i-acousto-optic crystal, i-piezoelectric transducer, umthombo we-RF drive, isisekelo sokusabalalisa ukushisa, kanye nesisekelo sokuxhumanisa se-optical. Imodyuli ngayinye isebenza ndawonye ukuqinisekisa ukuzinza kokuguquguquka.
1. Ikristalu le-Acousto optic: Isithwali esiyinhloko sokusebenzisana kwe-acousto-optic, okuyizinto eziyinhloko ezinquma ibhendi yemvamisa yokuguquguquka, ibhendi yemvamisa yokudlulisa, kanye nomkhawulo womonakalo. Amakristalu asetshenziswa njalo ahlukaniswe ngezigaba ezintathu: i-quartz ehlanganisiwe efanele i-laser engu-1064nm/CO ₂, efanele izimo zezimboni ezinamandla aphezulu; I-TeO ₂ inezici ezinhle zemvamisa ephezulu futhi iyilungiselelo elijwayelekile lemishini yokumaka amandla amancane naphakathi; I-Gallium phosphide iyahambisana ne-laser ye-ultraviolet engu-355nm yokulungisa ngokunemba.
2. I-transducer ye-piezoelectric: inamathiselwe ebusweni bekristalu ukuze kufezwe ukuguqulwa kwe-electroacoustic, imikhiqizo ephezulu isebenzisa inqubo yokushisela ye-vacuum enokushisa okuphansi ukuze kuthuthukiswe ukuthembeka.
3. Umthombo womshayeli we-RF: i-electronic control core, ehlukaniswe ngezigaba ezimbili: Umshayeli wedijithali we-TTL uthembele emazingeni aphezulu naphansi ukuvula nokuvala i-RF, okuyisisombululo esiyinhloko sokumaka kwezimboni; Ukushayela okulingisiwe kufeza ukulungiswa okuqhubekayo kokukhanya ngokulungisa amandla e-RF, avame ukusetshenziswa ezimweni zocwaningo lwesayensi. Ububanzi bemvamisa yokushayela evamile bungu-20MHz ~ 400MHz.
4. Isisekelo sokushabalalisa ukushisa: amandla aphezuluI-AOM Modulatorngokupholisa amanzi, ukupholisa umoya we-aluminium alloy ukuze kube namandla amancane naphakathi ukuze kugwenywe ukwehla kwezinga lokushisa eliphezulu lokusebenza kahle kokuphambuka.
5. Isisekelo Esibonakalayo: Umshini oqondile ongalungisa kahle i-engeli yesigameko ukuqinisekisa ukuthi i-laser iyenzeka nge-engeli yeBragg.
