Dual ifayibha imveliso enye frequency laser kwi 780 nm Umfanekiso Featured

I-fiber ephindwe kabini iphuma kwi-laser frequency enye kwi-780 nm

Umzekelo:

Inkcazelo emfutshane:

Iqela le-Erbium liphuhlisa i-dual-channels single frequency fiber laser enamandla amakhulu aphumayo ukuya kuthi ga kwi-1W/2W yeGravimeter gradiometer esekwe kwi-athomu ebandayo ye-Rb.Umahluko ophindaphindayo phakathi kwezi tshaneli zimbini unokutshixwa ngesantya sokubetha/isigaba sokutshixa.Izibuko eziphumayo ze-1560/780 nm laser zinokuodolwa, ezibonelela ngomthombo wokukhanya ophezulu wokusebenza kwegravimeter, i-quantum optics njalo njalo.I-laser yembewu, i-amplifier kunye nemodyuli ephindwe kabini ye-double-channel 1560 nm laser idityaniswe kwimeko encinci yokupholisa umoya.Umatshini wonke unesakhiwo esincinci, esizinzileyo kunye nokusebenza okuthembekileyo, kwaye unokudlula ukungcangcazela kunye neemvavanyo eziphezulu zokushisa.

IParameter yobuGcisa

Iithegi zeMveliso

Iimpawu zemveliso

█Ububanzi bomgca obumxinwa<20 kHz(phantsi njenge-2 kHz)

█Ukuzikhethela ingxolo yobukhulu obuphantsi (RIN <-130 dBc/Hz @ 100 kHz)

█Amandla aphezulu(2W)

█Umgangatho ogqwesileyo webeam (M² <1.1)

█Uzinzo lwamandla (PP<1% @25℃, <2% @15-35℃)

█Ukuzinza kokusingqongileyo (15-35℃, 0.5 Grms (0-200 Hz))

█Rb atom

█Isibane somlingo

█I-tweezer yokukhanya

■ Ukusebenza kwempembelelo yobushushu obuphezulu kunye nesezantsi

∎ Uzinzo rhoqo phantsi kwefuthe eliphezulu neliphantsi lobushushu

■ Ukugcinwa kweqondo lokushisa eliphantsi eliphezulu

Iziko le-frequency drift ye-0 ℃ -50 ℃ imalunga ne-340 MHz, kwaye iziko le-25 ℃ iiyure ezi-2 malunga ne-40 MHz.

Uvavanyo logcino oluphezulu noluphantsi lwefuthe lobushushu kwi- -30 ℃ -70 ℃ lubonise ukuba i-laser yokusebenza eqhelekileyo emva komothuko ophezulu nophantsi wobushushu.

■ Uzinzo lwamandla e-RMS phantsi kwefuthe eliphezulu neliphantsi lobushushu

Ukuzinza komjelo wokuqala kwindawo nganye yokushisa kwiqondo lokushisa eliphezulu eliphantsi lilinganiswe.Uzinzo lwamandla e-2-yure ye-RMS kwiqondo lokushisa elilinganiselweyo lika-0℃ kunye ne-50℃ lalingcono kune-0.2%

Uzinzo lwamandla lwetshaneli yesibini lukwangcono kune-0.2% (indawo yobushushu enye, i-RMS)

Imbewu ine-interface egciniweyo yokutshayela, kwaye uluhlu lokutshayela lwe-laser lwe-780nm lumalunga ne-3.2GHz.

Ukukhetha indawo efanelekileyo yokutshixa i-frequency kunye nokulawula umahluko ofanelekileyo wefrikhwensi kunye nokutshintsha rhoqo phakathi kwamajelo amabini, iziteshi ezimbini ze-780 nm laser eziveliswe yi-PreciLasers zinokubonelela ngazo zonke ii-lasers ezifunekayo kuvavanyo lwe-rubidium atomic gravimeter.Imveliso inokuguquguquka okuhle kokusingqongileyo kwaye lolona khetho lubalaseleyo kumthombo welaser wegravimeter yeathom enokuthuthwa.
