Xakamaynta inta jeer ee garaaca wadnahatignoolajiyada xakameynta garaaca wadnaha laser
1. Fikradda garaaca garaaca wadnaha, heerka garaaca garaaca leysarka (Heerka celceliska garaaca wadnaha) waxaa loola jeedaa tirada garaaca laysarka ee la sii daayo hal mar, badiyaa Hertz (Hz). Garaacyada soo noqnoqda ee sarreeya waxay ku habboon yihiin codsiyada heerka celceliska sarreeya, halka garaaca garaaca wadnaha hooseeya ay ku habboon yihiin tamar sare oo hal garaac ah.
2. Xidhiidhka u dhexeeya awoodda, ballaca garaaca wadnaha iyo inta jeer ka hor inta aan la xakameynin inta jeer ee laser, xiriirka ka dhexeeya awoodda, ballaca garaaca wadnaha iyo inta jeer waa in marka hore la sharaxo. Waxaa jira isdhexgal adag oo u dhexeeya awoodda laysarka, inta jeer iyo ballaca garaaca wadnaha, iyo hagaajinta mid ka mid ah halbeegyada inta badan waxay u baahan tahay tixgelinta labada cabbir ee kale si kor loogu qaado saameynta codsiga.
3. Hababka xakamaynta soo noqnoqda garaaca wadnaha ee caadiga ah
a. Habka kontoroolka dibeddu wuxuu ku shubaa calaamada soo noqnoqda ee ka baxsan sahayda korantada, oo waxay hagaajisaa inta jeer ee garaaca garaaca leysarka iyadoo la xakameynayo inta jeer iyo wareegga waajibaadka calaamada rarka. Tani waxay u oggolaaneysaa garaaca garaaca garaaca inuu la mid dhigo calaamadda culeyska, taasoo ka dhigaysa mid ku habboon codsiyada u baahan xakameyn sax ah.
b. Habka kontoroolka gudaha Calaamadaha kontoroolka soo noqnoqda waxa lagu dhex dhisay sahayda korantada wadista, iyada oo aan lahayn calaamado dibadeed oo dheeraad ah. Isticmaalayaashu waxay kala dooran karaan inta u dhaxaysa soo noqnoqoshada la dhisay ee go'an ama inta jeer ee kontoroolka gudaha lagu hagaajin karo dabacsanaan weyn.
c. Hagaajinta dhererka resonator-ka amamodulator-ka-elektarooniga ahSifooyinka soo noqnoqda ee laysarka waxa lagu beddeli karaa iyadoo la hagaajinayo dhererka resonator-ka ama iyadoo la isticmaalayo modulator-ka elektro-optical. Habkan nidaaminta soo noqnoqoshada sare ayaa inta badan loo adeegsadaa codsiyada u baahan awood celcelis sare ah iyo ballacyada garaaca wadnaha oo gaaban, sida micromachining laser iyo sawir-caafimaad.
d. Modulator Optic Modulator(AOM Modulator) waa qalab muhiim u ah xakamaynta soo noqnoqda garaaca wadnaha ee tignoolajiyada xakamaynta garaaca wadnaha.AOM Modulatorwaxay isticmaashaa saamaynta acousto optic (taas oo ah, cadaadiska oscillation-ka farsamada ee mowjadda dhawaaqa ayaa beddela index refractive) si loo habeeyo loona xakameeyo laydhka laysarka.
4. Tiknoolajiyada wax-ka-beddelka ee intracavity, marka la barbar dhigo modulation dibadda, habaynta daloolku waxay si hufan u dhalin kartaa tamar sare, awoodda ugu sarreysalaser garaaca wadnaha. Kuwa soo socdaa waa afar farsamo oo wax ka beddelka dalool-god oo caadi ah:
a. Gain Bedelka by si degdeg ah u habaynta isha bamka, kasbashada tirada qayb dhexdhexaadka ah rogan iyo faa'iido ayaa si degdeg ah loo aasaasay, dhaaftay heerka shucaaca kiciyey, taasoo keentay in koror fiiqan ee photons ee godka iyo jiilka laser garaaca garaaca gaaban. Habkani wuxuu si gaar ah ugu badan yahay lasers-ka semiconductor, kaas oo soo saari kara garaaca garaaca nanoseconds ilaa tobanaan picoseconds, oo leh qiyaasta ku celcelinta dhowr gigahertz, waxaana si ballaaran loo isticmaalaa dhinaca isgaarsiinta indhaha oo leh heerka gudbinta xogta sare.
Beddelka Q (Q-beddelashada) Q-dareemaha waxay xakameeyaan jawaab-celinta indhaha iyagoo soo bandhigaya khasaare sare oo ku jira godka laysarka, taas oo u oggolaanaysa habka bamgareynta inuu soo saaro dib-u-noqosho dadweyne oo ka fog marinka, kaydinta xaddi badan oo tamar ah. Ka dib, luminta godka ayaa si degdeg ah loo yareeyaa (taas oo ah, qiimaha Q ee godka ayaa kor u kacaya), iyo jawaab celinta indhaha ayaa mar kale loo rogay, si tamarta kaydka ah loo sii daayo qaabka garaaca sare ee ultra-gaaban.
c. Qaabka qufulku waxa uu abuuraa garaacyo gaagaaban oo picosecond ah ama xitaa heerka femtosecond iyada oo la xakameynayo xidhiidhka wejiga ee ka dhexeeya hababka dhererka ee kala duwan ee godka laysarka. Tiknoolajiyada qaabka-qufulka waxay u qaybsan tahay hab-quful iyo quful firfircoon.
d. Daloosha Daloosha Iyada oo tamarta lagu kaydiyo sawir-qaadayaasha ku jira resonator-ka, iyada oo la isticmaalayo muraayad dalool khasaare yar leh si ay si wax ku ool ah ugu xidho sawir-qaadayaasha, iyada oo la ilaalinayo xaalad khasaare hoose ah oo ku jirta godka muddo wakhti ah. Hal wareeg oo wareeg ah ka dib, garaaca garaaca wadnaha ee xoogga leh ayaa laga "tuuray" godka iyada oo si degdeg ah loo beddelo xubinta gudaha ee godka, sida modulator acousto-optic ama shutter electro-optic, iyo laser garaaca garaaca gaaban ayaa soo baxaya. Marka la barbardhigo Q-beddelka, faaruqinta daloolku waxay ilaalin kartaa ballaca garaaca wadnaha dhowr nanoseconds ee heerarka soo noqnoqda sare (sida dhowr megahertz) waxayna u oggolaaneysaa tamarta garaaca wadnaha sare, gaar ahaan codsiyada u baahan heerarka soo noqnoqda sare iyo garaaca garaaca gaaban. Marka lagu daro farsamooyinka kale ee abuurista garaaca wadnaha, tamarta garaaca wadnaha ayaa la sii wanaajin karaa.
Xakamaynta garaaca wadnahaleysarkawaa geedi socod adag oo muhiim ah, kaas oo ku lug leh xakamaynta ballaca garaaca wadnaha, xakamaynta garaaca garaaca wadnaha iyo farsamooyin badan oo wax-ka-beddelka ah. Iyada oo la adeegsanayo xulashada macquulka ah iyo adeegsiga hababkan, waxqabadka laser si sax ah ayaa loo hagaajin karaa si loo daboolo baahiyaha xaaladaha kala duwan ee codsiga. Mustaqbalka, iyada oo soo ifbaxa joogtada ah ee alaabada cusub iyo teknoolajiyada cusub, tignoolajiyada xakameynta garaaca wadnaha ee lasers waxay keeni doontaa horumaro badan, waxayna kor u qaadi doontaa horumarintafarsamada laysarkajihada saxda ah ee sare iyo codsiga ballaaran.
