Kudzora Software
Preci-Lock interface
Kune iri nani laser frequency control, Preci-Lock inosiya mapfundo emuviri nemabhatani.Uye shanduko dzese dzeparameter uye kukiya kutonga kunoitwa nePC software.Preci-lock software inosanganisira mabasa ekutaurirana kutonga, referensi uye kukanganisa chiratidzo chekuratidzira, PID module paramita kugadzirisa, kukiya kutonga uye zvichingodaro.Kunze kweiyo inodiwa yekubatanidza yemuviri, iyo laser yekuvhara yekudzora inogona kuzadzikiswa zvizere nePreci Lock software.Kushanda kwakachena kwedhijitari kuri nyore kune mushandisi.Chimwe chinhu chePreci-Lock software ndeye otomatiki yekuvhara basa, iyo inogona kuona iyo otomatiki kukiya kwelaser frequency pasi peinonzwisisika parameter marongero.Mune otomatiki yekuvhara maitiro, Preci-Lock inogona kuona kukiya otomatiki, kuvhura kutonga uye kukiya zvakare kweiyo laser frequency.Iyi modhi inogona kuona iyo yakareba yakagadzikana kuvharika kwelaser frequency, kunyanya yakakodzera kune inotonhora yeatomu fizikisi kuyedza iyo inoda kwenguva yakareba inoenderera kuyerwa.
Muenzaniso
Seyo inoshanda zvizere yekuvhara yekudzora module, Preci-Lock inogona kusangana nezvakawanda zvinodikanwa zvekukiya frequency.Iyo frequency yekuvhara inogona kukamurwa kuita yemukati modulation uye yekunze modulation frequency kukiya zvinoenderana nekusiyana modulation.Iwo maviri ma frequency ekiyi nzira akasiyana musimboti nepo kubatanidzwa kwemuviri kwePreci-Lock kwakasiyanawo kwavari.
Rubidium atomu saturation absorption spectrum uye inoenderana chiratidzo chekukanganisa (kuruboshwe);
Internal modulation frequency stabilization results (kurudyi).
◆Kugadzikana Kwemukati Modulation Frequency
Yemukati modulation, iyo modulation siginecha uye mhinduro inoisa mhinduro pamwe chete kune laser kuburikidza neadder.Iyo frequency yekuvhara poindi inoenderana neye wave peak uye wave trough ye spectra.Yakajairika yemukati frequency kudzikamisa modulation inogamuchirwa mukuvhara-mu saturation absorption spectrum kana absorption spectrum frequency stabilization.
Rubidium atomu modulation transfer spectrum uye inoenderana kukanganisa chiratidzo (kuruboshwe);
External modulation frequency stabilization results (kurudyi).
◆Kudzikamisa Kwekunze Modulation Frequency
Kune ekunze modulation, iyo modulation siginecha uye mhinduro chiratidzo chakakamurwa uye chekunze
modulation chiratidzo inoiswa kune yekunze yakazvimirira modulator.Iyo frequency lock point inoenderana ne zero point ye spectra.Yakajairika yekunze frequency kudzikamisa modulation inogamuchirwa mune modulation yekufambisa spectrum kana PDH frequency kugadzikana.
