I-dual fiber okukhipha i-laser yefrikhwensi eyodwa ku-780 nm

Imodeli:

Incazelo emfushane:

Iqembu le-Erbium lakha i-dual-channel single frequency fiber laser enamandla amakhulu okukhipha afika ku-1W/2W weGravimeter gradiometer esekelwe ku-athomu ebandayo ye-Rb.Umehluko wemvamisa phakathi kwamashaneli amabili ungakhiywa nge-beat frequency/ phase locking technique.Amachweba okukhiphayo we-laser engu-1560/780 nm anga-odwa, okuhlinzeka ngomthombo wokukhanya osebenza kakhulu we-gravimeter, i-quantum optics nokunye.I-laser yembewu, i-amplifier kanye nemojula yokuphinda kabili imvamisa ye-laser ye-dual-channel 1560 nm ihlanganiswe ekesini elincane lokupholisa umoya.Wonke umshini unesakhiwo esihlangene, ukusebenza okuzinzile nokuthembekile, futhi ungadlula ukudlidliza nokuhlolwa kwezinga lokushisa eliphansi kakhulu.

Omaka bomkhiqizo

Izici zomkhiqizo

█Ububanzi bomugqa obuncane<20 kHz(phansi njengo-2 kHz)

█Umsindo ongakhetha kukho wokuqina okuphansi (RIN <-130 dBc/Hz @ 100 kHz)

█Amandla aphezulu(2W)

█Ikhwalithi ye-beam enhle kakhulu (M² <1.1)

█Ukuqina kwamandla (PP<1% @25℃, <2% @15-35℃)

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

█I-athomu ye-Rb

█I-Magic lightlattice

█I-Optical tweezer

■ Ukusebenza komthelela wokushisa okuphezulu nokuphansi

■ Ukuzinza kwemvamisa ngaphansi komthelela wezinga lokushisa eliphezulu neliphansi

■ Ukugcinwa kwezinga lokushisa eliphansi eliphezulu

I-Center frequency drift ye-0 ℃ -50 ℃ icishe ibe ngu-340 MHz, kanti isikhungo esingu-25 ℃ amahora ama-2 singama-40 MHz.

Ukuhlolwa kwesitoreji sokukhukhuleka komthelela wokushisa okuphezulu nokuphansi ku--30℃ -70℃ kubonise ukuthi ukusebenza kwe-laser okuvamile ngemva kokushaqeka okuphezulu nokuphansi kwezinga lokushisa.

■ Ukuqina kwamandla e-RMS ngaphansi komthelela wezinga lokushisa eliphezulu neliphansi

Ukuzinza kwesiteshi sokuqala endaweni ngayinye yezinga lokushisa ekuhlolweni kwezinga lokushisa eliphansi kakhulu kukalwa.Ukuzinza kwamandla we-RMS yamahora angu-2 ezingeni lokushisa elikhawulelwe elingu-0℃ no-50℃ bekungcono kuno-0.2%

Ukuqina kwamandla wesiteshi sesibili nakho kungcono kuno-0.2% (iphuzu lokushisa elilodwa, i-RMS)

Imbewu inesixhumi esibonakalayo esigodliwe sokushanela, futhi i-780nm laser frequency sweep range icishe ibe ngu-3.2GHz.

Ukukhetha iphoyinti elifanelekile lokukhiya imvamisa nokulawula umehluko ofanele wokuvama kanye nokushintshwa kwemvamisa phakathi kwamashaneli amabili, ishaneli ekabili engu-780 nm laser ekhiqizwe i-PreciLasers inganikeza wonke ama-lasers adingekayo ukuze kuhlolwe i-rubidium atomic gravimeter.Umkhiqizo unokuvumelana nezimo okuhle kwemvelo futhi uyisinqumo esihle kakhulu somthombo we-laser we-atomic gravimeter ephathekayo.
