Kuchinja tsika dzechinyakareModulator yeLiNbO3
Munguva pfupi yapfuura, chikwata chevaongorori muChina chakaburitsa patent yekugadzira tekinoroji yekukiya mafrequency elaser ichishandisa LiNbO3 modulator. Chinhu chikuru chepatent iyi isystem itsva yePDH (Pound Driver Hall) yekukiya mafrequency elaser iyo inoshandura nzira dzechinyakare.
1. Matambudziko ehunyanzvi hwechinyakare:
Masisitimu echinyakare ePDH frequency locking anowanzo shandisa lithium niobate (LiNbO3)modulator yemagetsi-optickugadzira mabhendi ekunze anodiwa. Nzira iyi ine matambudziko matatu makuru: kudhura kwakanyanya uye chimiro chakaoma (chinoda macircuits akaomarara eRF driver), kunzwa nharaunda (kuchinja kwetembiricha nekushushikana kunogona kutungamira nyore nyore kukushanda kusina kugadzikana), uye mhedzisiro ye residual amplitude modulation (RAM), iyo inogona kukonzera kusvetuka kwechiratidzo chekukiya uye kukanganisa zvakanyanya kugadzikana kwenguva refu kwesystem.
2. Mhinduro itsva:
Mapoka ekutsvagisa ekuChina akasiya zvachose modulator yechinyakare ye electro-optic. Chinhu chikuru chiri mukugadzirwa kwe "semiconductor optical amplifier (SOA amplifier) pamwe chete ne dual channel acousto-optic frequency shifter (AOM modulator)". Nheyo chaiyo ndeiyi: mushure mekupatsanura mbeu ye laser beam, mavirimodulator yeAOMZvinoshandiswa pakuchinjisa mafrequency nemazvo, uye ipapo mwenje miviri iyi inopinzwa muSOA amplifier kana yasvika pakuzara. Gadzira zvinobudirira chiratidzo che multi sideband chinodiwa pakukiya mafrequency ePDH nekushandisa nonlinear effects dzakadai se four wave mixing (FWM) mukatiSOA amplifier.
3. Zvakanakira mashandiro zvinounzwa ne:
Kugadzikana kwakanyanya: Midziyo yeSOA (yakadai sekurongedza mabhururu) yakabatanidzwa nekudzora tembiricha uye hainzwisisi kukanganiswa kwezvakatipoteredza, zvichibvisa zvinobudirira RAM kubva muchimiro chemuviri uye zvichiita kuti ikwanise kuvharika kwenguva refu nekuchenjera (zviri nani pane 5 × 10 ⁻¹¹/zuva).
Chiyero chepamusoro chesignal-to-noise: Nekudzora wega frequency shift ye dual AOM modulator, zvinokwanisika kuwana kuenderana kwakarurama pakati pe sideband frequency ne free spectral range (FSR) ye reference cavity, nokudaro zvichivandudza zvikuru signal-to-noise ratio ye error signal.
Kuderedza mitengo uye kuita kuti michina ive midiki: SOA amplifier inobvisa mamodulators emagetsi anodhura uye macircuit akaomarara, zvichingoda kutyaira kwemagetsi kuri nyore. Izvi zvinoita kuti sisitimu ive diki uye isingadhuri, izvo zvinobatsira kuti michina ive midiki uye inoshanda.
4. Mashandisirwo ekushandisa uye kudiwa kwemusika:
Tekinoroji iyi inonyatso sangana nekudiwa kukuru kwemasosi elaser akagadzikana zvakanyanya mukuvandudza tekinoroji yequantum, uye ine mikana yakawanda yekushandisa, kusanganisira:
Wachi yemwenje yakaiswa muchadenga nemotokari (inofanira kuramba kudedera kwakanyanya).
Quantum gravimeter uye cold atomu interferometer (inoshandiswa pakuongorora geology uye kufamba pasi pemvura).
Kunzwa kwe fiber optic kwepamusoro uye LiDAR.
Mumusika uripo iye zvino, kunyanya muminda yekutsvagisa kwesainzi, indasitiri yemauto, uye yendege dzekutengeserana, kune kuwedzera kukuru kwekudiwa kwemamodule e laser anodzorwa ega, asingadhuri, uye akasimba kubva kumakambani. Iyi tekinoroji ine patent inonyatso ratidza maitiro aya emusika.
