780nm ya laser inshuro yo gufunga module

Ibisobanuro bigufi:

Ubushakashatsi bukonje bwa atom hamwe na Rb bukenera laseri hamwe numurongo wihariye kandi itsinda rya Erbium ritangiza gahunda zitandukanye zo gufunga imirongo ya 780nm.Twubatsemo fibre yose ihuza fibre hamwe na sisitemu ihuriweho hamwe nibindi bikoresho bya fibre optique.Iyi module irashobora gutanga ibimenyetso bihamye bya SAS cyangwa MTS kandi hamwe na laser umugenzuzi wa Preci-Lock, gufunga inshuro hamwe nigihe kirekire kirekire gihamye kiragaragara.Itandukaniro ryinshuro hagati ya laseri ebyiri zigomba kugumana agaciro gahoraho mubigeragezo bimwe bya atome ikonje.Kuri 87Rb atom gravimeter, itandukaniro ryinshuro yo gukonjesha laser no gusubiramo lazeri igomba kuba hafi 6.6GHz naho kuri lazeri ebyiri za Raman agaciro ni 6.834GHz.PreciLasers yashyize ahagaragara progaramu yihariye ya laser igenzura Preci-Beat yo gufunga offset yumurongo uri hagati ya 50MHz kugeza 8GHz hamwe na tekinike yo gufunga / inshuro.

Module ihuriweho

Hamwe na module ihuza umwanya-wo gufunga module, PreciLasers yubaka fibre-fibre-ihuza imirongo yo gufunga module.Iyi module itanga ikimenyetso gihamye cya SAS cyangwa MTS kumurongo wa Rb D2 kandi spekiteri irashobora gutanga ibimenyetso byamakosa yo gufunga inshuro 780nm laser.

SAS na MTS ibimenyetso biva muburyo bwa optique module

Imikorere myinshi ya laser

Itsinda rya Erbium ritanga imikorere myinshi ya laser mugenzuzi wo gufunga inshuro zitandukanye.Umugenzuzi, witwa Preci-Gufunga ， yahujwe na modem, PID module na High-Voltage amplifier kandi irashobora gukora nka generator yerekana ibimenyetso, PID servo na shoferi wa PZT icyarimwe.Imikorere yose ya Preci Lock igenzurwa na software idafite buto yumubiri cyangwa knob.Umugenzuzi arashobora gukora muburyo butandukanye munsi yabigenewe.Muburyo bwimbere-moderi laser ifunzwe na SAS cyangwa AS mugihe muburyo bwo hanze-moderi moderi laser ifunze hamwe na tekinike ya MTS cyangwa PDH.

Imiyoboro myinshi,Itsinda rya Erbiumitanga undi mugenzuzi wa laser Preci-Beat yo gufunga inshuro nyinshi.Preci-Beat yahujwe na PFD na PID module kandi nayo igenzurwa na software.

Gufunga SAS

Gufunga inshuro hamwe na SAS bishingiye kuri Lock-in amplifier.Fata SAS ya 85Rb atom nkurugero, Preci-Lock ibona ibimenyetso bya SAS kuva module ihuriweho na optique hanyuma utange ibimenyetso byamakosa hamwe no gufunga amplifier, module ya PID muri Preci-Lock izahita ifunga inshuro ya 780nm laser.

SAS nibimenyetso byamakosa muri software ya Preci-Gufunga

Twubaka sisitemu ebyiri yigenga ya SAS-ifunga lazeri 780nm hanyuma tugakora ikizamini cyo gukubita laser hamwe nimbuto zabo 1560nm.Ibi birashobora kwerekana ituze ryo gufunga inshuro.
