Cov yam ntxwv ntawmAOM acousto-optic modulator
Nrog siab optical zog
AOM acousto-optic modulator tuaj yeem tiv taus lub zog laser muaj zog, ua kom ntseeg tau tias cov lasers muaj zog tuaj yeem hla tau zoo. Nyob rau hauv tag nrho-fiber laser txuas, lubfiber ntau acousto-optic modulatorconverts lub teeb nruam mus rau hauv lub teeb pulsed. Vim lub voj voog ua haujlwm tsis tshua muaj ntawm cov pulse optical, feem ntau ntawm lub teeb lub zog yog nyob rau hauv lub zero-order teeb. Thawj-txiav txim diffraction teeb thiab xoom-txiav teeb sab nraum lub acousto-optic siv lead ua propagated nyob rau hauv daim ntawv ntawm divergent Gaussian beams. Txawm hais tias lawv ua tau raws li kev sib cais nruj, ib feem ntawm lub teeb lub zog ntawm xoom-kev txiav txim lub teeb accumulates ntawm ntug ntawm lub optical fiber collimator thiab tsis tuaj yeem kis tau los ntawm optical fiber, nws thiaj li hlawv los ntawm optical fiber collimator. Cov qauv diaphragm tau muab tso rau hauv txoj kev kho qhov muag los ntawm kev hloov kho siab-precision rau-dimensional kom txwv tsis pub xa cov teeb pom kev sib txawv ntawm qhov nruab nrab ntawm lub collimator, thiab lub teeb xoom xaim xa mus rau lub tsev kom tiv thaiv lub teeb xoom los ntawm kev kub hnyiab tawm ntawm optical fiber collimator.
Lub sijhawm nce ceev
Nyob rau hauv tag nrho-fiber laser txuas, lub sij hawm ceev ceev ntawm lub optical mem tes ntawm AOMacouste-optic modulatorxyuas kom meej tias lub kaw lus teeb liab mem tes tuaj yeem dhau los ntawm qhov zoo tshaj plaws, thaum tiv thaiv lub suab nrov los ntawm kev nkag mus rau lub sij hawm-domain acouste-optic shutter (time-domain pulse gate). Lub hauv paus tseem ceeb kom ua tiav lub sijhawm nce ceev ntawm optical pulses lies nyob rau hauv txo lub sij hawm thauj mus los ntawm ultrasonic tsis los ntawm lub teeb beam. Cov hau kev tseem ceeb suav nrog txo lub duav txoj kab uas hla ntawm qhov teeb meem teeb pom kev zoo lossis siv cov khoom siv nrog lub suab nrov tshaj plaws los tsim cov acoust-optic crystals.

Tsawg zog noj thiab muaj kev ntseeg siab
Spacecraft muaj cov peev txheej tsawg, cov xwm txheej hnyav thiab ib puag ncig nyuaj, uas ua rau muaj kev xav tau ntau dua ntawm kev siv hluav taws xob thiab kev ntseeg siab ntawm optical fiber AOM modulators. Optical fiber ntauAOM modulatortxais yuav ib qho tshwj xeeb tangential acousto-optic siv lead ua, uas muaj lub siab acousto-optic zoo yam M2. Yog li ntawd, nyob rau hauv tib lub diffraction efficiency tej yam kev mob, yuav tsum tau tsav lub zog noj yog tsawg. Lub optical fiber ntau acoust-optic modulator txais qhov kev tsim hluav taws xob qis, uas tsis tsuas yog txo qhov kev thov rau kev tsav tsheb siv hluav taws xob thiab txuag cov peev txheej tsawg hauv lub dav hlau, tab sis kuj txo cov hluav taws xob hluav taws xob hluav taws xob ntawm lub teeb liab tsav tsheb thiab txo qhov kub siab ntawm qhov system. Raws li cov txheej txheem txwv (tso cai) ntawm cov khoom siv dav hlau, cov qauv siv lead ua kev teeb tsa ntawm optical fiber acousti-optic modulators tsuas yog siv cov txheej txheem silicone roj hmab ib leeg xwb. Thaum cov roj hmab silicone ua tsis tiav, cov txheej txheem kev siv lead ua yuav hloov pauv raws li kev vibration, uas tsis ua raws li cov txheej txheem ntawm cov khoom siv dav hlau. Nyob rau hauv qhov txuas laser, cov siv lead ua ntawm optical fiber ntau acoust-optic modulator yog tsau los ntawm kev sib txuas cov cuab yeej kho nrog silicone roj hmab sib txuas. Cov qauv kev teeb tsa ntawm sab sauv thiab sab hauv qab yog qhov sib luag li qhov ua tau, thiab tib lub sijhawm, qhov chaw sib cuag ntawm lub ntsej muag siv lead ua thiab cov vaj tsev teeb tsa tau ua kom tiav. Nws muaj qhov zoo ntawm qhov muaj zog cua sov dissipation peev thiab symmetrical kub qhov chaw faib khoom. Pa collimators yog kho los ntawm kev sib txuas ntawm silicone roj hmab. Nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias, lawv tuaj yeem hloov pauv, cuam tshuam cov khoom lag luam. Cov qauv siv tshuab tam sim no tau txais los kho qhov kho qhov muag fiber ntau collimator, uas txhim kho cov khoom ruaj khov thiab ua tau raws li cov txheej txheem ntawm cov khoom siv aerospace.
