780nm imodyuli yokutshixa imodyuli yelaser eboniswayo

780nm imodyuli yokutshixa i-laser frequency

Umzekelo:

Inkcazelo emfutshane:

Imifuniselo ye-athomu ebandayo kunye ne-Rb ifuna iilaser ezine-frequency ethile kwaye iqela le-Erbium lisungula iishedyuli ezahlukeneyo zokutshixa ii-780nm laser.Sakhe imodyuli yokutshixa i-fiber-eqhagamshelwe rhoqo ngenkqubo edibeneyo yokukhanya kunye nezinye izixhobo zefiber optical.Le modyuli inokubonelela nge-SAS ezinzileyo okanye isignali ye-MTS kunye kunye nomlawuli wethu we-laser u-Preci-Lock, ukutshixa okuphindaphindiweyo kunye nokuzinza kwexesha elide kuyenziwa.Umahluko wamatyeli phakathi kweelaser ezimbini kufuneka ugcine kwixabiso elingaguqukiyo kwezinye iimfuniselo zeathom ezibandayo.Kwi-87Rb yegravimeter ye-athomu, umahluko wokuphindaphinda kwelaser yokupholisa kunye nelaser ephinda ipump kufuneka ibe malunga ne-6.6GHz kwaye kwiilaser ezimbini zeRaman ixabiso yi-6.834GHz.Abakwa-PreciLasers baphehlelele isilawuli se-laser esikhethekileyo i-Preci-Beat yokutshixa i-offset frequency kuluhlu olusuka kwi-50MHz ukuya kwi-8GHz ngeendlela zokutshixa i-beat frequency/phase phase.

Imodyuli edibeneyo yokubona

Ngemodyuli edibeneyo yokutshixa i-spatial frequency, i-PreciLasers yakha imodyuli yokutshixa i-fiber-eqhagamshelwe yonke.Le modyuli inika uphawu oluzinzile lwe-SAS okanye lwe-MTS kumgca we-Rb D2 kwaye i-spectrum inokunika umqondiso wephutha lokuvala i-frequency 780nm laser.

Umqondiso we-SAS kunye ne-MTS ukusuka kwimodyuli edibeneyo ye-optical

Isilawuli se-laser esinemisebenzi emininzi

Iqela le-Erbium libonelela ngesilawuli se-laser esinemisebenzi emininzi yokutshixa rhoqo phantsi kweemeko ezahlukeneyo.Umlawuli, obizwa ngokuba yi-Preci-Lock, idityaniswe nemodem, imodyuli ye-PID kunye ne-High-Voltage amplifier kwaye inokusebenza njenge-generator yesignali yephutha, i-PID servo kunye nomqhubi we-PZT ngaxeshanye.Yonke imisebenzi ye-Preci Lock ilawulwa yisoftware ngaphandle kweqhosha lomzimba okanye iqhosha.Umlawuli unokusebenza kwimodi eyahlukileyo phantsi kokulungelelanisa.Ngaphantsi kwemowudi yangaphakathi ye-laser itshixiwe nge-SAS okanye i-AS ngelixa i-laser yemodemu yangaphandle itshixiwe nge-MTS okanye ubuchule bePDH.

Ukwenzela iilaser ezinamatshaneli amaninzi,Iqela le-Erbiuminikeza enye isilawuli laser Preci-Beat for offset frequency lokutshixa.I-Preci-Beat idityaniswe ne-PFD kunye nemodyuli ye-PID kwaye ilawulwa ngesofthiwe.

Iphaneli yangaphambili ye-Preci-Beat

SAS-ukutshixa

Ukutshixwa rhoqo nge-SAS kusekwe kwi-Lock-in amplifier.Thatha i-SAS ye-athomu ye-85Rb njengomzekelo, i-Preci-Lock ifumana isignali ye-SAS kwimodyuli edibeneyo ye-optical kwaye ivelise isibonakaliso sephutha kunye ne-lock in amplifier, imodyuli ye-PID kwi-Preci-Lock iya kuthi ivale i-frequency ye-780nm laser.

I-SAS kunye nomqondiso wempazamo kwi-software ye-Preci-Lock

Sakha iinkqubo ezimbini ezizimeleyo zokutshixa i-SAS ye-laser ye-780nm kwaye sithatha uvavanyo lokubetha nge-laser nge-laser yabo ye-1560nm yembewu.Oku kungabonisa uzinzo lokutshixa rhoqo.
