Uburyo bwo gushyira mu byiciro no guhindura uburyo modulator ya laser ishyirwa mu byiciro

Modulator ya laserni ubwoko bw'ibice bya laser bigenzura, ntabwo ari ibintu by'ibanze nk'amakristale, lenses n'ibindi bice, kandi ntabwo ari ibintu by'ingenzi nk'amalaser,ibikoresho bya laser, ni urwego rwo hejuru rwo guhuza, ubwoko n'imikorere y'ibicuruzwa byo mu bwoko bw'ibikoresho. Ukurikije uburyo urumuri rugaragara, bigaragara ko ibintu bigira ingaruka ku rumuri ari imbaraga A (r), phase Φ (r), frequency ω n'ibice bine by'icyerekezo cyo gukwirakwiza, mu kugenzura ibi bintu bishobora guhindura imiterere y'urumuri, modulator ya laser ijyanye nayo niyomodulator y'ubukana, modulator y'icyiciro, frequence shifter na deflector.

1. Modulator y'ubukana: ikoreshwa mu guhindura ubukana cyangwa uburebure bwa laser, aho ibikoresho bigabanya ubukana, amarembo y'urumuri ari byo bigaragazwa cyane, ndetse n'ibikoresho n'ibikoresho bihujwe nka diyabule z'igihe, ibigabanya ubukana bw'ingufu, ibigabanya urusaku.

2. Modulator y'icyiciro: ikoreshwa mu kugenzura icyiciro cy'umuraba, kwiyongera kw'icyiciro byitwa gutinda, kugabanuka kw'icyiciro byitwa lead. Hari ubwoko bwinshi bwa modulators z'icyiciro, kandi amahame y'imikorere yazo aratandukanye cyane, nka modulators za photoelastic, modulators za LN zihuta cyane, impapuro zo gutinda za crystal variable phase delay, nibindi, byose ni modulators z'icyiciro zishingiye ku mahame y'imikorere atandukanye.

3. Ihinduranya ry'amajwi: rikoreshwa mu guhindura ingano y'amajwi y'urumuri, rikoreshwa cyane muri sisitemu za laser zigezweho cyangwa ibikoresho byo gushushanya, hamwe n'ihinduranya ry'amajwi ry'amajwi nk'iry'ikigereranyo gisanzwe.

4. Deflector: ikoreshwa mu guhindura icyerekezo cyo gukwirakwiza imirasire, sisitemu isanzwe ya galvanometer ni imwe muri zo, hiyongereyeho galvanometer yihuta ya mems, deflector ya electro-optical na deflector ya acousto-optical.

Dufite igitekerezo rusange cya modulator ya laser, ni ukuvuga ibice bishobora kugenzura no guhindura imiterere imwe n'imwe ya laser, ariko twifuza kwinjiza byimazeyo ibicuruzwa byihariye bya modulator ya laser, ingingo imwe gusa ntabwo ihagije. Rero, mbere ya byose, shyira imbaraga kuri modulator. Modulator y'ingufu nk'ubwoko bwa modulator ikoreshwa cyane mu bwoko bwose bwa sisitemu z'amatara, ubwoko bwayo, imikorere itandukanye ishobora gusobanurwa nk'igoye, uyu munsi kugira ngo tugusobanurire gahunda enye zisanzwe za modulator y'ingufu: gahunda ya mechanical, gahunda ya electro-optic, gahunda ya acousto-optic na gahunda ya crystal y'amazi.

1. Gahunda ya Mekanike: Mekanike yo gupima imbaraga niyo modulator y’imbaraga ya mbere kandi ikoreshwa cyane. Ihame ni uguhindura igipimo cy’urumuri rwa s n’urumuri rwa p mu rumuri rwa polarized uzungurutsa igice cy’urumuri, no kugabanya urumuri n’icyuma gipima imbaraga. Kuva ku ihinduka rya mbere ry’intoki kugeza kuri mashini ikoresha ikoranabuhanga ryikora cyane kandi rigezweho muri iki gihe, ubwoko bw’ibicuruzwa byayo n’iterambere ry’ikoreshwa byakuze cyane.

2. Gahunda ya Electro-optical: modulator y'imbaraga za electro-optical ishobora guhindura ubukana cyangwa ubwinshi bw'urumuri rwa polarized, ihame rishingiye ku ngaruka za Pockels za crystals za electro-optical. Imiterere ya polarization y'imirasire ya polarized irahinduka nyuma y'uko electro-optic crystal ifite amashanyarazi ikoreshejwe, hanyuma polarization igaburwa mu buryo bwihariye na polarizer. Ubukana bw'urumuri rusohoka bushobora kugenzurwa hakoreshejwe guhindura ubukana bw'urumuri rwa electromagnetic, kandi impera y'izamuka/igwa ry'ubunini bwa ns ishobora kugerwaho.

3. Gahunda ya Acousto-optic: modulator ya acousto-optic ishobora kandi gukoreshwa nk'imashini ikoresha imbaraga. Mu guhindura imikorere y'urumuri, imbaraga z'urumuri 0 n'urumuri 1 zishobora kugenzurwa kugira ngo hagerwe ku ntego yo guhindura imbaraga z'urumuri. Irembo rya Acoustooptic (attenuator y'amajwi) rifite imiterere y'umuvuduko wihuta w'ihindagurika ry'urumuri n'umupaka wo kwangirika cyane.

4 Umuti wa kristu y'amazi: igikoresho cya kristu y'amazi gikunze gukoreshwa nk'ikibaho cy'umuraba uhinduka cyangwa icyuma gihindura imiterere, hakoreshejwe ingufu z'amashanyarazi ku mpera zombi z'agasanduku ka kristu y'amazi kugira ngo hongerwemo ikintu cyo gupima neza, gishobora gukorwamo icyuma gifunga kristu y'amazi cyangwa icyuma gipima imiterere, icyo gikoresho gifite umwanya munini unyuze mu mucyo, kandi gifite imiterere yo kwizerwa cyane.
