Xakamaynta soo noqnoqoshada garaaca wadnahatiknoolajiyada xakamaynta garaaca wadnaha ee laysarka

1. Fikradda ah heerka garaaca wadnaha, heerka garaaca wadnaha ee laysarka (Heerka Celceliska garaaca wadnaha) waxay tilmaamaysaa tirada garaaca laysarka ee la sii daayo halkii waqti ee cutubka, badanaa Hertz (Hz). Garaacyada soo noqnoqda ee sare waxay ku habboon yihiin codsiyada heerka soo noqnoqda ee sare, halka garaacyada soo noqnoqda ee hooseeya ay ku habboon yihiin hawlaha garaaca wadnaha ee hal mar ah ee tamarta sare leh.

2. Xiriirka ka dhexeeya awoodda, ballaca garaaca iyo soo noqnoqoshada Kahor xakamaynta soo noqnoqoshada laysarka, xiriirka ka dhexeeya awoodda, ballaca garaaca iyo soo noqnoqoshada waa in marka hore la sharxaa. Waxaa jira isdhexgal adag oo u dhexeeya awoodda laysarka, soo noqnoqoshada iyo ballaca garaaca, hagaajinta mid ka mid ah xuduudaha badanaa waxay u baahan tahay tixgelinta labada cabbir ee kale si loo wanaajiyo saameynta codsiga.

3. Hababka xakamaynta soo noqnoqoshada garaaca wadnaha ee caadiga ah

a. Habka xakamaynta dibadda wuxuu ku shubaa calaamadda soo noqnoqoshada meel ka baxsan korontada, wuxuuna hagaajiyaa soo noqnoqoshada garaaca laysarka isagoo xakameynaya soo noqnoqoshada iyo wareegga shaqada ee calaamadda rarista. Tani waxay u oggolaanaysaa garaaca wax soo saarka in la isku waafajiyo calaamadda rarista, taasoo ka dhigaysa mid ku habboon codsiyada u baahan xakameyn sax ah.

b. Habka xakamaynta gudaha Calaamadda xakamaynta soo noqnoqoshada waxaa lagu dhisay korontada darawalka, iyada oo aan lahayn wax soo gelin calaamado dibadeed oo dheeraad ah. Isticmaalayaashu waxay dooran karaan inta jeer ee la dhisay oo go'an ama inta jeer ee la hagaajin karo ee xakamaynta gudaha si loo helo dabacsanaan weyn.

c. Hagaajinta dhererka resonator-ka amamodulator-ka elektaroonigga ahAstaamaha soo noqnoqda ee laysarka waxaa lagu beddeli karaa iyadoo la hagaajinayo dhererka resonator-ka ama la adeegsanayo modulator elektro-optical ah. Habkan xakamaynta soo noqnoqoshada sare waxaa badanaa loo isticmaalaa codsiyada u baahan awood celcelis sare iyo ballaca garaaca gaaban, sida mishiinka laysarka iyo sawir-qaadista caafimaadka.

d. Modulator-ka Acousto optic(AOM Modulator) waa qalab muhiim u ah xakamaynta soo noqnoqoshada garaaca ee tignoolajiyada xakamaynta garaaca laysarka.Modulator AOMWuxuu adeegsadaa saameynta indhaha ee acousto (taas oo ah, cadaadiska dhaqdhaqaaqa ee hirarka dhawaaqa wuxuu beddelaa tusmada iftiinka) si uu u habeeyo oo uu u xakameeyo iftiinka laysarka.

4. Tiknoolajiyada wax ka beddelka gudaha, marka la barbar dhigo wax ka beddelka dibadda, wax ka beddelka gudaha godka ayaa si hufan u abuuri kara tamar sare, awood sare.laysarka garaaca wadnahaAfar farsamo oo caadi ah oo wax ka beddelka godadka gudaha ee soo socda:

a. Isbedelka Gain Iyada oo si degdeg ah loo habeeyo isha bamka, rogidda tirada walxaha dhexdhexaadka ah ee gain iyo isku-dhafka gain ayaa si degdeg ah loo aasaasay, taasoo ka sarreysa heerka shucaaca kiciya, taasoo keenta koror fiiqan oo ku yimaada photons-ka godka iyo soo saarista laser garaaca gaagaaban. Habkani wuxuu si gaar ah ugu badan yahay laser-yada semiconductor-ka, kuwaas oo soo saari kara garaacyo laga bilaabo nanoseconds ilaa tobanaan picoseconds, iyadoo leh heer ku celcelin ah oo ah dhowr gigahertz, waxaana si weyn loogu isticmaalaa dhinaca isgaarsiinta indhaha oo leh heerarka gudbinta xogta oo sarreeya.

Beddelka Q (Q-beddelka) Beddelka Q wuxuu joojiyaa jawaab celinta indhaha isagoo soo bandhigaya khasaarooyin badan oo ku jira godka laysarka, taasoo u oggolaanaysa habka bamgareynta inuu soo saaro dib-u-rogid tirada walxaha ka kooban oo ka baxsan xadka, taasoo kaydinaysa tamar badan. Dabadeed, khasaaraha godka ayaa si degdeg ah loo dhimaa (taasi waa, qiimaha Q ee godka ayaa la kordhiyaa), jawaab celinta indhahana mar kale ayaa la shidaa, si tamarta la keydiyay loogu sii daayo qaab garaaca xoogga sare ee aadka u gaaban.

c. Qaabka Qufulku wuxuu soo saaraa garaacyo aad u gaaban oo ah heerka picosecond ama xitaa femtosecond isagoo xakameynaya xiriirka wejiga ee u dhexeeya qaababka dhererka kala duwan ee godka laysarka. Tiknoolajiyadda qaabka qufulku waxay u qaybsan tahay qaabka qufulka aan firfircoonayn iyo qaabka qufulka firfircoon.

d. Daadinta Godadka Marka la kaydiyo tamarta photons-ka ku jira resonator-ka, iyadoo la isticmaalayo muraayad godka lumis yar si wax ku ool ah loogu xidho photons-ka, iyadoo la ilaalinayo xaalad lumis yar oo godka ah muddo ah. Ka dib hal wareeg oo wareeg ah, garaaca xoogga leh ayaa laga "tuuraa" godka iyadoo si dhakhso ah loo beddelayo curiyaha godka gudaha, sida modulator-ka acousto-optic ama shutter-ka electro-optic-ga, waxaana la sii daayaa laser garaaca gaaban. Marka la barbardhigo Q-beddelka, faaruqinta godka waxay ilaalin kartaa ballaca garaaca dhowr nanoseconds heerarka ku celcelinta sare (sida dhowr megahertz) waxayna u oggolaanaysaa tamar garaac oo sare, gaar ahaan codsiyada u baahan heerarka ku celcelinta sare iyo garaaca gaaban. Marka lagu daro farsamooyinka kale ee soo saarista garaaca, tamarta garaaca ayaa si dheeraad ah loo horumarin karaa.

Xakamaynta garaaca wadnahalaysarwaa hab-socod adag oo muhiim ah, kaas oo ku lug leh xakamaynta ballaca garaaca, xakamaynta soo noqnoqoshada garaaca iyo farsamooyin badan oo wax-ka-beddel ah. Iyada oo loo marayo xulasho macquul ah iyo codsi hababkan, waxqabadka laysarka si sax ah ayaa loo hagaajin karaa si loo daboolo baahiyaha xaaladaha kala duwan ee codsiyada. Mustaqbalka, iyadoo si joogto ah loo soo saarayo agabyo cusub iyo teknoolojiyad cusub, tignoolajiyada xakamaynta garaaca ee laysarka waxay keeni doontaa horumarro badan, waxayna kor u qaadi doontaa horumarintatiknoolajiyada laysarkajihada saxnaanta sare iyo codsiga ballaaran.
