Maumbirwo ehurongwa hwemodulator yeacousto-optical
Acoustic Optical Modulator (AOM Modulator) parizvino ndiyo inoshandiswa zvakanyanya kunze kwelaser cavity, iri mu external modulation technology system. Inoshandisa acousto-optic coupling kuti iite beam on/off, intensity uye frequency control. Ndiyo modulation scheme inonyanya kushandiswa mu industrial laser marking, precision cutting, scientific research optical path, uye small and medium power laser radar equipment.
Kuumbwa kwehurongwa,
Zvosekushandura kweacousto-opticSisitimu iyi ine zvikamu zvishanu zvikuru: acousto-optic crystal, piezoelectric transducer, RF drive source, heat dissipation base, uye optical coupling base. Module yega yega inoshanda pamwe chete kuti ive nechokwadi chekuti modulation yagadzikana.
1. Acousto optic crystal: Chinhu chikuru chinotakura acousto-optic interaction, inova chinhu chakakosha chinosarudza modulation frequency band, transmission frequency band, uye damage threshold. Makristaro anowanzoshandiswa akakamurwa kuita zvikamu zvitatu: fused quartz yakakodzera 1064nm/CO ₂ laser, yakakodzera maindasitiri ane simba guru; TeO ₂ ine hunhu hwakanaka hwe high-frequency uye igadziriro yakajairwa yemichina midiki neyepakati yekumaka magetsi; Gallium phosphide inoenderana ne 355nm ultraviolet laser yekugadzira nemazvo.
2. Piezoelectric transducer: yakanamatwa pamucheto wekristaro kuti iite shanduko yemagetsi, zvigadzirwa zvepamusoro-soro zvinoshandisa nzira yekuwelding ye vacuum ine tembiricha yakaderera kuti ivandudze kuvimbika.
3. RF driver source: electronic control core, yakakamurwa muzvikamu zviviri: TTL digital driver inoshandisa mazinga akakwira neakaderera kuti ibate nekudzima RF, inova ndiyo mhinduro huru yekuisa chiratidzo mumaindasitiri; Simulated driving inoita kuti chiedza chirambe chichigadziriswa nekuchinja simba reRF, iro rinowanzoshandiswa muongororo yesainzi. Frequency yekutyaira yakajairika ndeye 20MHz ~ 400MHz.
4. Hwaro hwekuparadza kupisa: simba guruModulator yeAOMnekutonhodza kwemvura, kutonhodza kwemhepo yearuminiyamu alloy kuti pave nesimba diki nepakati kudzivirira kudzikira kwekushanda zvakanaka kwe diffraction pakupisa kwakanyanya.
5. Optical Base: Chishandiso chakanyatsogadzirwa chinogona kugadzirisa kona yechiitiko kuti ive nechokwadi chekuti laser yaitika pakona yeBragg.
