Imojuli yokukhiya imvamisa ye-laser engu-780nm Isithombe esifakiwe

780nm laser frequency locking module

Imodeli:

Incazelo emfushane:

Ukuhlolwa kwe-athomu ebandayo nge-Rb kudinga ama-laser anefrikhwensi ethile futhi iqembu le-Erbium lethula amashejuli ahlukene okukhiya imvamisa ye-laser engu-780nm.Sakhe imojuli yokukhiya imvamisa exhunywe yonke i-fiber enohlelo oludidiyelwe lwamehlo namanye amadivaysi efiber optical.Le mojula inganikeza isignali ye-SAS noma ye-MTS ezinzile futhi kanye nesilawuli sethu se-laser i-Preci-Lock, ukukhiya imvamisa ngokuzinza okuhle kwesikhathi eside kuyabonakala.Umehluko wemvamisa phakathi kwama-laser amabili kufanele ugcine inani elingashintshi kwezinye izivivinyo ze-athomu ezibandayo.Ku-87Rb athomu gravimeter, umehluko wemvamisa we-laser epholile kanye ne-laser repumping kufanele ibe ngu-6.6GHz futhi kumalaser amabili e-Raman inani lingu-6.834GHz.I-PreciLasers yethule isilawuli se-laser esikhethekile i-Preci-Beat sokukhiya imvamisa ye-offset ebangeni elisuka ku-50MHz ukuya ku-8GHz ngendlela yokukhiya imvamisa yebhithi/isigaba.

Imojula ye-optical ehlanganisiwe

Ngemojula edidiyelwe yokukhiya imvamisa yendawo, i-PreciLasers yakha imojuli yokukhiya imvamisa exhunywe yonke-fiber.Le mojula inikeza isignali ye-SAS noma ye-MTS ezinzile kulayini we-Rb D2 futhi i-spectrum inganikeza isignali yephutha yokuvala imvamisa ye-laser engu-780nm.

Isignali ye-SAS ne-MTS evela kumojula ye-optical edidiyelwe

Multi-function laser isilawuli

Iqembu le-Erbium linikeza isilawuli se-laser esinemisebenzi eminingi yokukhiya imvamisa ngaphansi kwezimo ezihlukile.Isilawuli, esiqanjwe ngo-Preci-Lock, sihlanganiswe nemodemu, imojula ye-PID ne-High-Voltage amplifier futhi singasebenza njengejeneretha yesiginali yephutha, i-PID servo kanye nomshayeli we-PZT ngesikhathi esifanayo.Yonke imisebenzi ye-Preci Lock ilawulwa isofthiwe engenayo inkinobho ebonakalayo noma i-knob.Isilawuli singasebenza ngemodi ehlukile ngaphansi kokwenza ngendlela oyifisayo.Ngaphansi kwemodi yokushintshashintsha kwangaphakathi i-laser ikhiywa nge-SAS noma i-AS kuyilapho i-laser yemodi yokumodareyitha yangaphandle ikhiywa nge-MTS noma ngobuchule be-PDH.

Okwama-laser aneziteshi eziningi,Iqembu le-Erbiuminikeza esinye isilawuli se-laser i-Preci-Beat sokukhiya imvamisa ye-offset.I-Preci-Beat ihlanganiswe ne-PFD ne-PID module futhi ilawulwa ngesofthiwe.

Iphaneli yangaphambili ye-Preci-Beat

I-SAS-locking

Ukukhiya imvamisa nge-SAS kusekelwe ku-Lock-in amplifier.Thatha i-SAS ye-athomu engu-85Rb njengesibonelo, i-Preci-Lock thola isignali ye-SAS kumojula ye-optical edidiyelwe futhi ikhiqize isignali yephutha nge-lock in amplifier, imojula ye-PID ku-Preci-Lock izobe ivala imvamisa ye-laser engu-780nm.

I-SAS nesignali yephutha kusofthiwe ye-Preci-Lock

Sakha amasistimu wokukhiya we-SAS amabili azimele we-laser engu-780nm futhi sithatha isivivinyo sokushaya nge-laser nge-laser yabo yembewu engu-1560nm.Lokhu kungabonisa ukuzinza kokukhiya imvamisa.
