Ukwakhiwa kwenkquboi-modulator ye-acousto-optical
I-Acoustic Optical Modulator (i-AOM Modulator) okwangoku sesona sixhobo sokuguqula esisetyenziswa kakhulu ngaphandle kwe-laser cavity, esikwinkqubo yetekhnoloji yokuguqula yangaphandle. Ixhomekeke kwiziphumo zomzimba ze-acousto-optic coupling ukuze kufezekiswe ukuvulwa/ukuvalwa kwe-beam, ubunzulu kunye nolawulo lwamaza. Sisicwangciso sokuguqula esisetyenziswa kakhulu kwi-industrial laser marking, ukusika ngokuchanekileyo, indlela ye-optical yophando lwesayensi, kunye nezixhobo ze-radar ye-laser enamandla amancinci naphakathi.
Ukwakhiwa kwenkqubo,
Ipheleleukuguquguqulwa kwe-acousto-opticInkqubo ineeyunithi ezintlanu eziphambili: i-acousto-optic crystal, i-piezoelectric transducer, umthombo we-RF drive, isiseko sokusasaza ubushushu, kunye nesiseko sokudibanisa i-optical. Imodyuli nganye isebenza kunye ukuqinisekisa uzinzo lwe-modulation.
1. I-Acousto optic crystal: Isixhobo esiphambili sokusebenzisana kwe-acousto-optic, esisixhobo esibalulekileyo esimisela ibhendi ye-modulation frequency, ibhendi ye-transmission frequency, kunye nomda womonakalo. Iikristale ezisetyenziswa rhoqo zahlulwe zibe ziindidi ezintathu: i-fused quartz efanelekileyo kwi-laser ye-1064nm/CO ₂, efanelekileyo kwiimeko zoshishino ezinamandla aphezulu; I-TeO ₂ ineempawu ezilungileyo ze-high-frequency kwaye luyilungiselelo oluqhelekileyo loomatshini abancinci nabaphakathi bokumakisha amandla; I-Gallium phosphide iyahambelana ne-355nm ultraviolet laser yokulungisa ngokuchanekileyo.
2. I-Piezoelectric transducer: incamatheliswe kwicala lekristale ukuze kufezekiswe ukuguqulwa kwe-electroacoustic, iimveliso eziphezulu zisebenzisa inkqubo yokuwelda yobushushu obuphantsi nge-vacuum ukuphucula ukuthembeka.
3. Umthombo womqhubi we-RF: i-electronic control core, eyahlulwe yangamacandelo amabini: Umqhubi wedijithali we-TTL uxhomekeke kumanqanaba aphezulu naphantsi ukuvula nokucima i-RF, esisisombululo esiphambili sokuphawula kwemizi-mveliso; Ukuqhuba okulingisiweyo kufezekisa ukulungiswa okuqhubekayo kokukhanya ngokulungelelanisa amandla e-RF, asetyenziswa rhoqo kwiimeko zophando lwesayensi. Uluhlu lwesiqhelo sokuqhuba luyi-20MHz ~ 400MHz.
4. Isiseko sokusasaza ubushushu: amandla aphezuluI-AOM Modulatorkunye nokupholisa amanzi, ukupholisa umoya we-aluminium alloy ukuze kubekho amandla amancinci naphakathi ukuze kuthintelwe ukwehla kobushushu obuphezulu bokusebenza kakuhle kwe-diffraction.
5. Isiseko se-Optical: Isixhobo esichanekileyo esinokulungisa i-engile yesiganeko ukuqinisekisa ukuba i-laser iyenzeka kwi-engile ye-Bragg.
