Tswj Software
Preci-Lock interface
Rau qhov zoo dua laser zaus tswj, Preci-Lock tso tseg cov pob qhov rooj thiab cov nyees khawm.Thiab tag nrho cov kev hloov pauv thiab kev tswj kev kaw haujlwm yog pom tau los ntawm PC software.Preci-lock software suav nrog kev ua haujlwm ntawm kev sib txuas lus tswj, siv thiab yuam kev teeb liab zaub, PID module tsis hloov kho, kev tswj kev ntsuas phoo thiab lwm yam.Tsuas yog qhov kev sib txuas ntawm lub cev tsim nyog, lub laser locking tswj tuaj yeem ua tiav los ntawm Preci Lock software.Kev ua haujlwm zoo digital yog yooj yim dua rau cov neeg siv.Lwm qhov tshwj xeeb ntawm Preci-Lock software yog qhov tsis siv neeg xauv lub luag haujlwm, uas tuaj yeem paub qhov tsis siv neeg kaw ntawm laser zaus raws li qhov tsim nyog qhov chaw.Hauv kev kaw qhov tsis siv neeg, Preci-Lock tuaj yeem paub nws pib xauv, qhib kev txiav txim thiab rov kaw ntawm lub laser zaus.Hom no tuaj yeem paub lub sijhawm ntev ruaj khov ntawm lub laser zaus, tshwj xeeb tshaj yog haum rau qhov kev sim txias atom physics uas yuav tsum tau ntsuas mus ntev.
Piv txwv
Raws li kev tswj hwm kev kaw haujlwm tag nrho, Preci-Lock tuaj yeem ua tau raws li qhov xav tau ntau zaus ntawm kev kaw haujlwm.Qhov zaus ntsuas phoo tuaj yeem muab faib ua qhov kev hloov kho sab hauv thiab sab nraud modulation zaus ntsuas phoo raws li qhov sib txawv ntawm qhov kev hloov kho.Ob txoj kev kaw qhov zaus sib txawv hauv txoj cai thaum lub cev sib txuas ntawm Preci-Lock kuj txawv rau lawv.
Rubidium atom saturation absorption spectrum thiab coj teeb meem yuam kev (sab laug);
Internal modulation zaus stabilization tshwm sim (txoj cai).
◆Stabilization Internal Modulation zaus
Rau kev hloov kho sab hauv, lub teeb liab modulation thiab cov lus qhia tawm tswv yim ua ke rau lub laser los ntawm ib qho adder.Qhov zaus ntsuas phoo taw tes sib raug rau nthwv dej ncov thiab nthwv dej ntawm lub spectra.Cov kev hloov hauv cov zaus stabilization tau txais los ntawm kev kaw-hauv saturation absorption spectrum lossis absorption spectrum zaus stabilization.
Rubidium atom modulation hloov spectrum thiab coj teeb meem yuam kev (sab laug);
Sab nraud modulation zaus stabilization tshwm sim (txoj cai).
◆Stabilization Sab Nraud Modulation zaus
Rau sab nraud modulation, lub teeb liab modulation thiab tawm tswv yim teeb liab muab faib thiab sab nraud
modulation teeb liab yog siv rau sab nraud ywj siab modulator.Qhov zaus ntsuas phoo taw tes sib raug mus rau xoom point ntawm lub spectra.Ib qho kev hloov pauv ntawm lwm zaus stabilization yog tau txais hauv kev hloov pauv hloov spectrum lossis PDH zaus stabilization.
