Ukuhlelwa kunye neskimu sokumodareyitha kwemodyuli ye-laser

Imodyuli yeLaserluhlobo lwamacandelo olawulo lwelaser, alunasiseko njengeekristale, iilensi kunye nezinye izinto, kwaye aludityaniswanga kakhulu njengelaser,izixhobo laser, yinqanaba eliphezulu lokudibanisa, iintlobo kunye nemisebenzi yeemveliso zeklasi yesixhobo. Ukusuka kwinkcazo eyinkimbinkimbi yokukhanya kokukhanya, kunokubonwa ukuba izinto ezichaphazela ukukhanya kokukhanya zinamandla A (r), isigaba Φ (r), i-frequency ω kunye nemiba emine yesalathiso sokusasaza, ngokulawula le miba inokutshintsha imeko yokukhanya, imodyuli ye-laser ehambelana nayoimodyuli yokuqina, imodyuli yesigaba, i-frequency shifter kunye ne-deflector.

1. Imodyuli yokuqina: isetyenziselwa ukumodareyitha ubunzulu okanye i-amplitude ye-laser, apho i-optical attenuators, amasango okukhanya awona amele kakhulu, kunye nezixhobo ezidibeneyo kunye nezixhobo ezifana nezahluli zexesha, i-stabilizers yamandla, i-attenuators yengxolo.

2. Imodyuli yenqanaba: isetyenziselwa ukulawula isigaba se-beam, ukunyuka kwesigaba kubizwa ngokuba yi-lag, ukuhla kwesigaba kubizwa ngokuba yi-lead. Kukho iintlobo ezininzi zeemodyuli zesigaba, kunye nemigaqo yazo yokusebenza yahluke kakhulu, njengeemodyuli ze-photoelastic, i-LN high-speed electro-optical phase modulators, i-liquid crystal variable phase sheet sheets, njl.

3. I-Frequency shifter: isetyenziselwa ukutshintsha ukuphindaphinda kwamaza okukhanya, isetyenziswa ngokubanzi kwiinkqubo ze-laser eziphezulu okanye izixhobo zemephu, kunye ne-acousto-optical frequency shifter njengommeli oqhelekileyo.

4. I-Deflector: isetyenziselwa ukutshintsha isalathiso sokusasaza kwe-beam, inkqubo ye-galvanometer eqhelekileyo yenye yazo, ngaphezu kweemems ezikhawulezayo ze-galvanometer, i-electro-optical deflector kunye ne-acousto-optical deflector.

Sinombono oqhelekileyo wemodyuli yelaser, oko kukuthi, amacandelo anokulawula ngamandla kwaye atshintshe iipropathi ezithile zomzimba welaser, kodwa sifuna ukwazisa ngokupheleleyo iimveliso ezithile zemodyuli yelaser, linqaku kuphela elikude ngokwaneleyo. Ke, okokuqala, gxila kwimodyuli yokuqina. I-intensity modulator njengohlobo lwemodyuli esetyenziswa ngokubanzi kuzo zonke iintlobo zeenkqubo zokukhanya, ukuhlukahluka kwayo, ukusebenza okungafaniyo kunokuchazwa njengento enzima, namhlanje ukukwazisa isikimu semodyuli esiqhelekileyo esinesiqhelo: iskimu somatshini, iskimu se-electro-optic, iskimu se-acousto-optic kunye neskimu sekristale yamanzi.

1. Iskimu soomatshini: imodyuli yamandla yoomatshini yeyona imodyuli yamandla yokuqala kwaye isetyenziswa kakhulu. Umgaqo kukutshintsha umlinganiselo we-s ukukhanya kunye ne-p ukukhanya ekukhanyeni kwe-polarized ngokujikeleza ipleyiti yesiqingatha-amaza, kunye nokwahlula ukukhanya nge-polarizer. Ukusuka kuhlengahlengiso lokuqala lwencwadi ukuya kumatshini wanamhlanje wokusebenza okuphezulu kunye nokuchaneka okuphezulu, iintlobo zayo zemveliso kunye nophuhliso lwesicelo sele ikhulile kakhulu.

2. Iskimu se-Electro-optical: i-electro-optical intensity modulator inokutshintsha ubukhulu okanye i-amplitude yokukhanya kwe-polarized, umgaqo usekelwe kwi-Pockels effect ye-electro-optical crystals. Imeko ye-polarization ye-polarized beam itshintsha emva kokuba i-crystal ye-electro-optic enentsimi yombane isetyenzisiwe, kwaye ke i-polarization ihlukaniswe ngokukhethiweyo yi-polarizer. Ukuqina kokukhanya okukhutshiweyo kunokulawulwa ngokuguqula ubuninzi bombane, kunye nokunyuka / ukuwa kwe-ns ubukhulu kunokufikelela.

3. Iskim se-acousto-optic: imodyuli ye-acousto-optic nayo ingasetyenziswa njengemodyuli yokuqina. Ngokutshintsha ukusebenza kwe-diffraction, amandla okukhanya kwe-0 kunye nokukhanya kwe-1 anokulawulwa ukufezekisa injongo yokulungelelanisa ukukhanya kokukhanya. Isango le-Acoustooptic (i-optical attenuator) ineempawu zesantya sokumodareyitha ngokukhawuleza kunye nomda womonakalo omkhulu.

I-4 isisombululo sekristale yolwelo: isixhobo se-crystal ye-liquid sihlala sisetyenziswa njengeplati ye-wave wave okanye i-filter eguqulwayo, ngokufaka i-voltage ye-drive kuzo zombini iziphelo zebhokisi ye-crystal ye-liquid ukongeza into echanekileyo ye-polarization, inokwenziwa kwi-shutter ye-crystal ye-liquid okanye i-attenuator eguquguqukayo, imveliso ine-aperture enkulu ngokukhanya, ukuthembeka okuphezulu iimpawu.
