Ukukhanya kulawula ukukhanya

Kutshanje, iqela labaphandi abavela eUnited States naseKhanada bapapashe uhlolisiso oluye lwenziwa lubhengeza ukuba baye babonisa ngempumelelo ukuba umqa welaser unokuvelisa izithunzi njengento eyomeleleyo phantsi kweemeko ezithile. Olu phando lucela umngeni ekuqondweni kweengqikelelo zesithunzi zemveli kwaye luvula amathuba amatsha olawulo lwe-laser. Umsebenzi, onesihloko esithi "Shadow of laser beam," wapapashwa kwijenali edumileyo i-Optica. Ngokwesiko, izithunzi zidla ngokudalwa zizinto ezingacacanga ezithintela umthombo wokukhanya, kwaye ukukhanya ngokuqhelekileyo kunokudlula kwezinye izibane ngaphandle kwemiqobo, ngaphandle kokuphazamisana. Nangona kunjalo, izazinzulu ziye zafumanisa ukuba phantsi kweemeko ezithile, i-laser beam ngokwayo inokusebenza "njengento eqinile", ithintele enye i-beam yokukhanya kwaye ngaloo ndlela iphosa isithunzi endaweni. Esi siganeko sibonga ukuqaliswa kwenkqubo ye-optical nonlinear evumela ukuba enye i-beam yokukhanya idibanise nomnye ngokuxhomekeka kobunzima bezinto eziphathekayo, ngaloo ndlela ichaphazela indlela yayo yokusabalalisa kunye nokudala umphumo wesithunzi. Kuvavanyo, abaphandi basebenzise i-laser ye-laser eluhlaza enamandla ukuba badlule kwikristale yeruby ngelixa bekhanyisa i-laser beam eluhlaza ukusuka ecaleni. Xa uluhlazalaseringena kwi-ruby, itshintsha ekuhlaleni impendulo yempahla ekukhanyeni okuluhlaza okwesibhakabhaka, yenza i-laser beam eluhlaza isebenze njengento eqinile, ivimbela ukukhanya okuluhlaza okwesibhakabhaka. Oku kusebenzisana kubangela indawo emnyama ekukhanyeni okuluhlaza okwesibhakabhaka, indawo yomthunzi we-laser eluhlaza.

Esi siphumo "somthunzi we-laser" sisiphumo sokungeniswa okungaqhelekanga ngaphakathi kwekristale yeruby. Ngokukodwa, i-laser eluhlaza iphucula ukunyuswa kokukhanya okuluhlaza okwesibhakabhaka, idala ummandla wokukhanya okusezantsi ngaphakathi kwendawo ekhanyisiweyo, idala isithunzi esibonakalayo. Esi sithunzi asinakujongwa ngokuthe ngqo ngeso lenyama kuphela, kodwa kunye nesimo saso kunye nesikhundla sinokuhambelana nesimo kunye nokuma kwe-laser beam, ukuhlangabezana nazo zonke iimeko zesithunzi sendabuko. Iqela lophando lenze uphando olunzulu ngale nto kwaye lalinganisa ukuchasana kwezithunzi, nto leyo ebonisa ukuba ukuchasana okukhulu kwezithunzi kufikelele malunga ne-22%, kufana nokungafani kwezithunzi ezenziwe yimithi elangeni. Ngokuseka imodeli yethiyori, abaphandi baqinisekisa ukuba imodeli inokuqikelela ngokuchanekileyo ukutshintshwa komthunzi wethunzi, obeka isiseko sokusetyenziswa ngakumbi kwethekhnoloji. Ukusuka kumbono wobugcisa, oku kufunyaniswa kunezicelo ezinokubakho. Ngokulawula ukuhanjiswa koxinzelelo lwe-laser enye ukuya kwenye, obu buchwepheshe bunokusetyenziswa ekutshintsheni ukukhanya, ulawulo lokukhanya oluchanekileyo kunye namandla aphezulu.ukuhanjiswa kwelaser(ukuhanjiswa kwamehlo). Olu phando lubonelela ngesikhokelo esitsha sokuphonononga intsebenziswano phakathi kokukhanya nokukhanya, kwaye kulindeleke ukuba kukhuthaze uphuhliso olongezelelweyo lweiteknoloji yamehlo.
