I-Electro-Optical Modulator (Xothi) Ilawula amandla, isigaba kanye ne-polarization yogongolo lwe-laser ngokulawula ngogesi.
Okulula kakhuluI-Electro-Optic ModulatoraIsilinganiselo sesigabaequkethe ibhokisi elilodwa le-pockels kuphela, lapho insimu kagesi (isetshenziswa ku-crystal nge-electrode) ishintsha ukubambezeleka kwesigaba sogongolo lwe-laser ngemuva kokungena kwikristalu. Isimo sombala sokwehla kwesigameko kwesinye isikhathi sidinga ukufana nesinye sezimbatho zekristalu zekristalu ukuze isimo se-polarization sogongolo singashintshi.
Kwezinye izimo kuphela isigaba esincane sesigaba (ngezikhathi ezithile noma i-aperoidic) siyadingeka. Isibonelo, i-Eom ivame ukusetshenziselwa ukulawula futhi iqinise imvamisa emibi yalabo abadambisayo bokubona. Ama-mod modwonars ahlukahlukene ajwayele ukusetshenziswa ezimweni lapho kudingeka khona ukuguqulwa kwezikhathi ezithile, futhi ukujula okukhulu kokuphonswa kungatholwa ngogesi olinganiselayo wokushayela. Kwesinye isikhathi ukujula kokumodula kukhulu kakhulu, futhi i-sidelobe eminingi (i-generator ekhanyayo, i-light comp) ikhiqizwa ku-spectrum.
Modulator polarization
Ngokuya ngohlobo nokuqondisa kwe-crystal engajwayelekile, kanye nokuqondiswa kwenkambu yangempela kagesi, ukubambezeleka kwesigaba kuhlobene nokuqondisa kwe-polarization. Ngakho-ke, ibhokisi lePockels lingabona amapuleti alawulwa ama-wave alawulwa ama-wave amaningi, futhi futhi libuye lisetshenziselwe ukuguqula izizwe ze-polarization. Ukukhanya okufakwayo okucacile okusobala (imvamisa endaweni engama-45 ° kusuka ku-axis yekristalu), ukubambana kombala wokukhipha kuvame ukujikeleza ukukhanya okuvela kokukhanya okusobala okuqondile.
Modulator amplitude
Lapho kuhlanganiswa nezinye izinto ezibonakalayo, ikakhulukazi ngama-polarizers, amabhokisi wePockels angasetshenziselwa ezinye izinhlobo zokushintshashintsha. I-Modulator ye-Amplide in Umdwebo 2 isebenzisa ibhokisi le-pockels ukushintsha isimo se-polarization, bese isebenzisa i-polarizer ukuguqula ushintsho engozini enkulu yokushintshwa kanye nokukhanya okudlulisiwe.
Ezinye izinhlelo zokusebenza ezijwayelekile zama-electro-optic modulars zifaka:
Ukuguqula amandla ka-laser ugongolo, ngokwesibonelo, ekuphrintiwe kwe-laser, ukuqoshwa kwedatha yedijithali ephezulu, noma ukucophelela okuphezulu kwejubane;
Isetshenziswa ezindaweni zokuqina ze-laser imvamisa yokuqina, ngokwesibonelo, kusetshenziswa indlela ye-pound-DRELER-HALL;
Q ukushintshwa kwama-lasers aqinile wombuso (lapho kusetshenziswa khona i-EOM ukuvala i-laser resonator ngaphambi kwemisebe edonswayo);
Imodi esebenzayo-Lock-Lognation elahlekayo yokulahleka kwe-cavity noma esigabeni sokukhanya kohambo lokuzungeza, njll.);
Ukushintsha ama-pulses ku-Pulse Picters, ama-amplifiers amahle ama-amplifiers kanye nama-lasers wokulinganisa.
