Hunhu hwemodulator yeAOM acousto-optic
Ramba nesimba repamusoro remaziso
Modulator yeAOM acousto-optic inogona kutsungirira simba rakasimba relaser, zvichiita kuti malaser ane simba guru agone kupfuura zvakanaka. Mukubatanidza kwelaser ine fiber yese,modulator ye fiber acousto-opticInoshandura chiedza chinoenderera mberi kuita chiedza chakatenderera. Nekuda kwekushanda kwakaderera kwemhepo inoyerera, simba guru rechiedza riri mukati mechiedza chezero-order. Chiedza chekutanga che diffraction nechiedza chezero-order kunze kwekristaro ye acousto-optic zvinopararira muchimiro chemwenje yeGaussian yakasiyana-siyana. Kunyangwe zvichisangana nemamiriro ekupatsanurwa kwakasimba, chikamu chesimba rechiedza chezero-order chinoungana pamucheto we optical fiber collimator uye hachigone kupfuudzwa kuburikidza ne optical fiber, pakupedzisira chichipfuta kuburikidza ne optical fiber collimator. Chimiro che diaphragm chinoiswa munzira ye optical kuburikidza ne high-precision six-dimensional adjustment frame kuti chidzivise kutapurirana kwechiedza chakapararira pakati pe collimator, uye chiedza chezero-order chinopfuudzwa kuimba kudzivirira chiedza chezero-order kuti chisapfute optical fiber collimator.
Nguva yekukwira nekukurumidza
Mune link yelaser ine fiber yese, nguva yekukwira nekukurumidza kwe optical pulse yeAOMmodulator yeacouste-opticinoita kuti chiratidzo chesystem signal pulse chigone kupfuura nepakati zvakanaka, uku ichidzivirira ruzha rwebase kuti rusapinde mu time-domain acouste-optic shutter (time-domain pulse gate). Chinhu chikuru chekuwana nguva yekukwira nekukurumidza kwema optical pulses ndechekuderedza nguva yekufamba kwema ultrasonic waves kuburikidza nechiedza. Nzira huru dzinosanganisira kuderedza dhayamita yechiuno chechiedza chechiitiko kana kushandisa zvinhu zvine ruzha rwakanyanya kugadzira makristaro e acoust-optic.

Kushandiswa kwesimba kwakaderera uye kuvimbika kwakanyanya
Zvikepe zvemuchadenga zvine zviwanikwa zvishoma, mamiriro ezvinhu akaomarara uye nharaunda dzakaoma, izvo zvinoita kuti pave nezvinodiwa zvakanyanya pakushandiswa kwesimba uye kuvimbika kwema optical fiber AOM modulators.modulator yeAOMinoshandisa kristaro yakasarudzika ye tangential acousto-optic, ine acousto-optic quality factor M2 yakakwira. Saka, pasi pemamiriro akafanana ekushanda zvakanaka kwe diffraction, simba rekutyaira rinodiwa rakaderera. Optical fiber acoust-optic modulator inoshandisa dhizaini iyi ine simba shoma, iyo isingangoderedzi chete kudiwa kwesimba rekutyaira uye inochengetedza zviwanikwa zvishoma muspacecraft, asiwo inoderedza mwaranzi yemagetsi yechiratidzo chekutyaira uye inoderedza kumanikidzwa kwekupisa pasystem. Zvichienderana nezvinodiwa (zvakarambidzwa) zvemaitiro ezvigadzirwa zvespacecraft, nzira yemazuva ano yekuisa kristaro ye optical fiber acousti-optic modulators inongoshandisa nzira ye single-sided silicone rubber bonding process. Kana silicone rabber yakundikana, technical parameters yekristaro ichachinja mumamiriro e vibration, izvo zvisingasangane nezvinodiwa zvemaitiro ezvigadzirwa zveaerospace. Mu laser link, kristaro ye optical fiber acoust-optic modulator inogadziriswa nekubatanidza mechanical fixation ne silicone rubber bonding. Maumbirwo ekuisa pamusoro nepazasi akaenzana sezvinobvira, uye panguva imwe chete, nzvimbo yekubatana pakati pepamusoro pekristaro nenzvimbo yekuisa inowedzera. Ine zvakanakira simba rakasimba rekupisa uye kugoverwa kwenzvimbo yekupisa kwakaenzana. Ma collimator akajairwa anogadziriswa ne silicone rabha inosunga. Kana tembiricha yakakwira uye ichidedera, anogona kuchinja, zvichikanganisa mashandiro echigadzirwa. Chimiro chemuchina ikozvino chave kushandiswa kugadzirisa optical fiber collimator, iyo inowedzera kugadzikana kwechigadzirwa uye inosangana nezvinodiwa zvemaitiro ezvigadzirwa zvemuchadenga.
