Ukuqonda umahluko phakathi kweLaser kunye nokuKhanya okuQhelekileyo kunye nendlela iLaser eveliswa ngayo

Itekhnoloji yeLaser iguqule amashishini ahlukeneyo, ukusuka kwimveliso ukuya kukhathalelo lwezempilo. Kodwa yintoni eyenza ukukhanya kwelaser kwahluke kukukhanya okuqhelekileyo? Eli nqaku liphonononga umahluko ophambili kunye nenkqubo esisiseko yokuveliswa kwelaser.

Umahluko phakathi kweLaser kunye nokukhanya okuqhelekileyo

1. I-Monochromaticity: Ukukhanya kweLaser kunomsebenzi ogqwesileyo we-monochromaticity, oku kuthetha ukuba iqulathe ubude obunye kunye nobubanzi obumxinwa kakhulu bomgca wembonakalo. Ngokwahlukileyo, ukukhanya okuqhelekileyo ngumxube wamaza amaza amaninzi, okukhokelela kwi-spectrum ebanzi.

2. Ukuqaqamba kunye noxinzelelo lwamandla: Imiqadi yeLaser inokukhanya okuphezulu kakhulu kunye nokuxinana kwamandla, okubavumela ukuba bagxininise amandla amakhulu kwindawo encinci. Ukukhanya okuqhelekileyo, ngelixa kubonakala, kunokukhanya okuphantsi kakhulu kunye nokugxila kwamandla. Ngenxa yokukhutshwa kwamandla aphezulu e-lasers, izisombululo zokupholisa ezisebenzayo, ezifana ne-industrial water chillers, zibalulekile ukugcina ukusebenza okuzinzileyo kunye nokuthintela ukushisa.

3. Umkhombandlela: Imiqadi yeLaser inokusasaza ngendlela ehambelana kakhulu, igcina i-angle encinci yokuhlukana. Oku kwenza iilaser zilungele usetyenziso oluchanekileyo. Ukukhanya okuqhelekileyo, kwelinye icala, kukhanya kwiindlela ezininzi, okukhokelela kukusasazwa okubalulekileyo.

4. Ukuyondelelana: Ukukhanya kweLaser kuhambelana kakhulu, okuthetha ukuba amaza ayo anefrikhwensi efanayo, isigaba, kunye nesalathiso sosasazo. Oku kuhambelana kwenza izicelo ezifana neholografi kunye nonxibelelwano lwefiber optic. Ukukhanya okuqhelekileyo akunalu lungelelwaniso, kunye namaza ako abonisa izigaba kunye nezalathiso ezingaqhelekanga.

Kwenziwa njani ukukhanya kweLaser

Inkqubo yokuveliswa kwelaser isekelwe kumgaqo wokukhutshwa okuvuselelweyo. Ibandakanya la manyathelo alandelayo:

1. Ukuvuselela amandla: Iiathomu okanye iiathomu kwi-laser medium (efana negesi, eqinile, okanye i-semiconductor) ifunxa amandla angaphandle, ii-electron eziguqukayo ukuya kwimeko ephezulu yamandla.

2. Ukuguqulwa kwabemi: Imeko iphunyeziwe apho amasuntswana amaninzi akhoyo kwimeko echulumancisayo kunemeko ephantsi yamandla, edala inversion yabemi-imfuneko ebalulekileyo kwisenzo se-laser.

3. Ukukhutshwa okuvuselelweyo: Xa i-athomu echulumancisayo idibana nefoton engenayo yobude obuthile bobude, ikhupha ifoton efanayo, ikhulisa ukukhanya.

4. I-Optical Resonance kunye noKwandiswa: Iifotoni ezikhutshwayo zibonakalisa ngaphakathi kweresonator yamehlo (iperi yezibuko), ngokuqhubekayo ikhulisa njengoko iifotoni ezininzi zivuselelwa.

5. Laser Beam Output: Nje ukuba amandla afikelele kumda obalulekileyo, umqadi welaser ohambelanayo, okhokelayo kakhulu ukhutshwa ngesipili esibonakalisa inxenye, silungele ukusetyenziswa. Njengoko iilaser zisebenza kumaqondo obushushu aphezulu, ukudibanisa i i-industrial chiller  inceda ukulawula ubushushu, iqinisekisa ukusebenza kwelaser okungaguqukiyo kunye nokwandisa ubomi besixhobo.

Ukuqukumbela, ukukhanya kwelaser kuma ngaphandle kokukhanya okuqhelekileyo ngenxa yeempawu zayo ezizodwa: i-monochromaticity, uxinano lwamandla aphezulu, ulwalathiso olubalaseleyo, kunye nokuhambelana. Indlela echanekileyo yokuvelisa i-laser ivumela ukusetyenziswa kwayo ngokubanzi kwiindawo ezinqamlekileyo ezifana nokulungiswa kwemizi-mveliso, utyando lwezonyango, kunye nonxibelelwano lwamehlo. Ukwandisa ukusebenza kwenkqubo ye-laser kunye nokuphila ixesha elide, ukuphumeza i-chiller yamanzi ethembekileyo yinto ephambili ekulawuleni ukuzinza kwe-thermal.
