Fibre ebyiri isohoka inshuro imwe ya laser kuri 780 nm

Icyitegererezo:

Ibisobanuro bigufi:

Itsinda rya Erbium ritezimbere imiyoboro ibiri ya fibre laser hamwe nimbaraga nyinshi zisohoka kugeza 1W / 2W kuri Gravimeter gradiometero ishingiye kuri atom ikonje ya Rb.Itandukaniro ryumurongo hagati yimiyoboro yombi irashobora gufungwa na beat frequency / tekinike yo gufunga tekinike.Ibisohoka ibyambu bya 1560/780 nm laser birashobora gutumizwa, bitanga imikorere yumucyo mwinshi wa gravimeter, kwant optique nibindi.Imbuto ya lazeri, amplifier hamwe ninshuro ebyiri inshuro ebyiri zumuyoboro wa 1560 nm lazeri zahujwe mukantu gato gukonjesha ikirere.Imashini yose ifite imiterere yoroheje, ikora neza kandi yizewe, kandi irashobora gutsinda ibinyeganyega hamwe nubushyuhe bwo hasi cyane.

Stability Guhagarara inshuro nyinshi munsi yubushyuhe buke kandi buke

Kubika ubushyuhe buke

Hagati yumurongo wa 0 ℃ -50 ℃ ni 340 MHz, naho hagati ya 25 ℃ kumasaha 2 ni 40 MHz

Ubushakashatsi bwubushyuhe bwo hejuru nubushyuhe bwo kubika inshuro -30 ℃ -70 ℃ bwerekanye ko laser ikora bisanzwe nyuma yubushyuhe bwo hejuru kandi buke.

RMS imbaraga za RMS munsi yubushyuhe bwo hejuru kandi buke

Igihagararo cyumuyoboro wa mbere kuri buri bushyuhe bwapimwe mubipimo byo hasi yubushyuhe byapimwe.Imbaraga zihamye za RMS yamasaha 2 kubushyuhe bwa 0 ℃ na 50 ℃ byari byiza kurenza 0.2%

Imbaraga zihamye zumuyoboro wa kabiri nazo ziruta 0.2% (ingingo yubushyuhe bumwe, RMS)

Imbuto ifite interineti yabugenewe yo gusiba, kandi 780nm ya laser yohanagura ni 3.2GHz.

Guhitamo umwanya uhagije wo gufunga no kugenzura itandukaniro rikwiye hamwe no guhinduranya inshuro hagati yimiyoboro yombi, imiyoboro ibiri 780 nm laser yakozwe na PreciLasers irashobora gutanga lazeri zose zikenewe mugupima gravimeter ya rubidium.Igicuruzwa gifite imiterere ihindagurika y’ibidukikije kandi ni amahitamo meza kuri laser isoko ya atomic gravimeter itwarwa.
