780nm module quful inta jeer laser

Qaabka:

Sharaxaad Gaaban:

Tijaabooyinka atomka qabow ee Rb waxay u baahan yihiin lasers oo leh soo noqnoqosho gaar ah iyo kooxda Erbium waxay soo saartaa jadwalyo xidhid joogto ah oo kala duwan oo loogu talagalay 780nm laser.Waxaan dhisnay moduleka qufulka soo noqnoqda ee fiber-ku-xiran oo leh nidaam isku-dhafan iyo aaladaha kale ee fiber indhaha.Qeybtaani waxay bixin kartaa calaamad SAS ama MTS deggan oo ay weheliso kontoroolka laysarka ee Preci-Lock, quful joogta ah oo leh xasillooni waqti dheer ah ayaa la xaqiiqsaday.Farqiga soo noqnoqda ee u dhexeeya labada laysarka waa inuu ku hayaa qiime joogto ah tijaabooyinka atamka qabow qaarkood.Marka loo eego 87Rb atom gravimeter, farqiga soo noqnoqda ee qaboojinta laysarka iyo laser repuping waa in ay ahaataa qiyaastii 6.6GHz iyo labada laysar ee Raman qiimahoodu waa 6.834GHz.PreciLasers waxay soo saartay koontaroole laser khaas ah Preci-Beat oo loogu talagalay xirida soo noqnoqda ee inta u dhaxaysa 50MHz ilaa 8GHz oo leh garaac garaaca soo noqnoqda/farsamada qufulka.

module indhaha isku dhafan

Iyada oo la adeegsanayo moduleka xirida soo noqnoqda ee isku dhafan, PreciLasers waxay dhistaa dhammaan-fiber-ku xidhidh moduleka xirida soo noqnoqda.Qaybtani waxay ku siinaysaa calaamad SAS ama MTS deggan oo ku taal khadka Rb D2 iyo spectrum-ku wuxuu bixin karaa calaamadda qaladka qufulka inta jeer ee laser 780nm.

Xakamaynta laser-ka-shaqo badan

Kooxda Erbium waxay bixisaa kontaroolaha laser-ka shaqeeya ee badan oo loogu talagalay qufulka inta jeer ee xaalad kala duwan.Xakameeyaha, oo loo yaqaan Preci-Lock, wuxuu ku dhexjiraa modem, module PID iyo cod-weyneeye sare oo Voltage ah wuxuuna u shaqeyn karaa sidii koronto-dhaliyaha qaladka, PID servo iyo darawalka PZT isku mar.Dhammaan shaqada Preci Lock waxaa gacanta ku haya software aan lahayn badhan jireed ama buro.Kantarooluhu wuxuu ku shaqayn karaa qaab kala duwan oo hoos yimaada habaysan.Habka qaabaynta gudaha laser-ka waxaa lagu quful SAS ama AS halka habka-modulation-ka dibeda leysarka lagu xiray farsamada MTS ama PDH.

Laysarka kanaalka badan,Kooxda Erbiumwuxuu bixiyaa kontaroole kale oo leysarka Preci-Beat oo loogu talagalay qufulka soo noqnoqda.Preci-Beat waxaa lagu dhex daray PFD iyo module PID waxaana sidoo kale lagu maamulaa software.

Kooxda hore ee Preci-Beat

SAS-quful

Qufulka soo noqnoqda ee SAS waxay ku salaysan tahay cod-weyneeye Quful.Qaado SAS ee atomka 85Rb tusaale ahaan, Preci-Lock hel signalka SAS moduleka isku dhafan ee indhaha oo abuura calaamad khalad ah oo quful ku jira cod-weyneeye, moduleka PID-ga ee Preci-Lock ayaa markaa xidhi doona inta jeer ee laser 780nm.

SAS iyo calaamada khaldan ee software Preci-Lock

Waxaan u dhisnay laba nidaam oo SAS-quful ah oo madax-bannaan oo loogu talagalay 780nm laser waxaanan ku qaadnaa tijaabada garaaca laysarka iyadoo la adeegsanayo laambadahooda 1560nm.Tani waxay muujin kartaa xasiloonida qufulka soo noqnoqda.
