Itekhnoloji ye-fiber bundle iphucula amandla kunye nokukhanya kwe-blue semiconductor laser

Itekhnoloji ye-fiber bundle iphucula amandla kunye nokukhanya kwe-i-laser ye-semiconductor eluhlaza okwesibhakabhaka

Ukubumba imiqadi kusetyenziswa ubude bexesha obufanayo okanye obusondeleyoilezaIyunithi sisiseko sokudibanisa imisebe yelaser emininzi yeewavelengths ezahlukeneyo. Phakathi kwazo, ukudibanisa imisebe yendawo kukufaka imisebe yelaser emininzi esithubeni ukwandisa amandla, kodwa kunokubangela ukuba umgangatho womsebe unciphe. Ngokusebenzisa uphawu lwe-linear polarization lwei-laser ye-semiconductor, amandla eemitha ezimbini apho ulwalathiso lokungcangcazela luthe nkqo omnye komnye lunokwandiswa phantse kabini, ngelixa umgangatho wemitha uhlala ungatshintshi. I-Fiber bundler sisixhobo sefayibha esilungiselelwe ngokusekelwe kwi-Taper Fused Fiber Bundle (TFB). Yeyokususa inqwaba yomaleko we-optical fiber coating, uze ulungelelaniswe ngendlela ethile, ufudunyezwe kubushushu obuphezulu ukuze uyinyibilikise, ngelixa usolula i-optical fiber bundle kwicala elichaseneyo, indawo yokufudumeza i-optical fiber iyanyibilika ibe yi-fused cone optical fiber bundle. Emva kokunqumla isinqe se-cone, hlanganisa isiphelo sesiphumo se-cone nge-output fiber. Itekhnoloji ye-fibre bunching inokudibanisa ii-fiber bundles ezininzi ezizimeleyo zibe yi-bundle enobubanzi obukhulu, ngaloo ndlela ifezekisa ukuhanjiswa kwamandla aphezulu e-optical. Umfanekiso 1 ngumzobo we-schematic weileza eluhlaza okwesibhakabhakaiteknoloji yefayibha.

Indlela yokudibanisa imisebe ye-spectral isebenzisa into enye yokusasazeka kwe-chip ukuze idibanise imisebe emininzi ye-laser ngaxeshanye kunye namaxesha obude obuphantsi njenge-0.1 nm. Imisebe emininzi ye-laser yamaza ahlukeneyo iyenzeka kwi-dispersive element kwii-engile ezahlukeneyo, idlule kwi-element, ize i-diffract kwaye iphume kwicala elifanayo phantsi kwesenzo sokusasazeka, ukuze umsebe we-laser odibeneyo udlule omnye komnye kwindawo ekufutshane nakwintsimi ekude, amandla alingana nesimbuku seemisebe zeyunithi, kwaye umgangatho wemisebe uyahambelana. Ukuze kufezekiswe indibaniselwano ye-spectral beam enesithuba esincinci, i-diffraction grating ene-dispersion enamandla idla ngokusetyenziswa njenge-beam combination element, okanye i-surface grating edityaniswe ne-external mirror feedback mode, ngaphandle kolawulo oluzimeleyo lwe-spectrum yeyunithi ye-laser, okunciphisa ubunzima kunye neendleko.

I-laser eluhlaza okwesibhakabhaka kunye nomthombo wayo wokukhanya odibeneyo kunye ne-infrared laser zisetyenziswa kakhulu kwicandelo lokuwelda kwesinyithi esingena-ferrous kunye nokuveliswa kwezongezo, ukuphucula ukusebenza kakuhle kokuguqulwa kwamandla kunye nokuzinza kwenkqubo yokuvelisa. Izinga lokufunxwa kwe-laser eluhlaza okwesibhakabhaka kwiintsimbi ezingenanto linyuswa ngamaxesha aliqela ukuya kumaxesha alishumi kunele-laser ye-wavelength ekufutshane ne-infrared, kwaye ikwaphucula i-titanium, i-nickel, isinyithi kunye nezinye iintsimbi ukuya kwinqanaba elithile. Ii-laser eziluhlaza okwesibhakabhaka ezinamandla aphezulu ziya kukhokela utshintsho lokuveliswa kwe-laser, kwaye ukuphucula ukukhanya kunye nokunciphisa iindleko yindlela yophuhliso yexesha elizayo. Ukuveliswa kwezongezo, ukugquma kunye nokuwelda kweesinyithi ezingenanto kuya kusetyenziswa kakhulu.

Kwinqanaba lokukhanya okuphantsi okuluhlaza okwesibhakabhaka kunye neendleko eziphezulu, umthombo wokukhanya odibeneyo we-laser eluhlaza okwesibhakabhaka kunye ne-laser ekufutshane ne-infrared unokuphucula kakhulu ukusebenza kakuhle kokuguqulwa kwamandla kwemithombo yokukhanya ekhoyo kunye nokuzinza kwenkqubo yokuvelisa phantsi kwesiseko seendleko ezilawulekayo. Kubaluleke kakhulu ukuphuhlisa iteknoloji yokudibanisa imisebe ye-spectrum, ukusombulula iingxaki zobunjineli, kunye nokudibanisa iteknoloji yeyunithi ye-laser yokukhanya okuphezulu ukuze kufezekiswe umthombo we-laser ye-semiconductor eluhlaza okwesibhakabhaka ekhanyayo kakhulu, kunye nokuhlola iteknoloji entsha yokudibanisa imisebe. Ngokwanda kwamandla e-laser kunye nokukhanya, nokuba ngumthombo wokukhanya othe ngqo okanye ongathanga ngqo, i-laser eluhlaza okwesibhakabhaka iya kuba yinto ebalulekileyo kwicandelo lokhuselo lwesizwe kunye noshishino.
