Kugabanya ubugari bw'umurongo wa laser

Kugabanya ubushobozi bwaUbugari bw'umurongo wa laser

Ubugari bw'umurongo wa laser bufitanye isano itaziguye n'ubwoko bwa laser. Ubugari bw'umurongo wa laser bushobora kugabanywa binyuze mu kunoza imiterere ya laser no kugabanya ingaruka z'urusaku rwo hanze uko bishoboka kose. Intambwe ya mbere ni ukumenya urusaku runini, urusaku rwa quantum cyangwa urusaku rwa kera, kuko bizagira ingaruka ku bipimo bikurikira.

Iyo imbaraga zo mu kanwa zirenze urugero, igihombo cya resonator kiba gito kandi igihe cyo gusubira no kugaruka cya resonator kikaba kirekire, urusaku rwa quantum rwalaser(cyane cyane urusaku rw'ibyuka bisohoka mu buryo bwihuse) rugira ingaruka nto cyane. Urusaku rwa kera rushobora guterwa no gukurura ibintu mu buryo bw'ikoranabuhanga. Guhindagurika kw'ibintu bishobora kugabanywa hakoreshejwe resonator ngufi ya laser, ariko rimwe na rimwe muri resonator ngufi, guhindagurika k'uburebure bishobora gutanga ingaruka zikomeye. Igishushanyo mbonera cy'ikoranabuhanga gishobora kugabanya imikoranire hagati ya resonator ya laser n'imirasire yo hanze, ndetse no kugabanya ingaruka z'ubushyuhe. Hariho kandi guhindagurika k'ubushyuhe mu buryo bw'ingufu, biterwa n'ihindagurika ry'ingufu za pompe.

Kugira ngo urusaku rurusheho gukora neza, hagomba gukoreshwa ibindi bikoresho bihamye, ariko ni byiza kubanza gukoresha uburyo bufatika bwo kudakoresha imbaraga. Ubugari bw'umurongo wa laser ifite frequency imwe nalaser ya fibreni kilohertz nyinshi, ndetse rimwe na rimwe na munsi ya 1KHz. Ukoresheje uburyo bwo gushimangira imikorere, ubugari bw'umurongo buri munsi ya 1KHz bushobora kuboneka. Ubugari bw'umurongo bwa diode za laser busanzwe buri mu rwego rwa MHZ kandi bushobora no kugabanywa kuri KHz, nko muri laser za diode zo hanze, cyane cyane kuri diode zitanga ibitekerezo by'urumuri zifite umwobo wo hejuru.

Ni ngombwa kumenya ko mu bihe bimwe na bimwe,isoko y'urumuri rwa laserntabwo bikenewe kugira ngo habeho ubugari bw'urumuri ruto cyane:

1. Iyo uburebure bw'ubuhuza ari burebure, ingaruka z'ubuhuza (kubera kugaragara nabi kw'ibimera) zizabangamira imiterere y'urumuri. Mu kwerekana imiterere ya laser, ingaruka z'amabara zishobora kubangamira ubwiza bw'ubuso bugaruka.

2. Iyo urumuri rwoherejwe mu migozi y'urumuri ikora cyangwa idakora, ubugari bw'umurongo muto butera ibibazo bimwe na bimwe bitewe no gukwirakwira kwa Brillouin. Muri iki gihe, ubugari bw'umurongo bugomba kongerwa, urugero, hakoreshejwe guhindura diode ya laser hamwe n'umuyoboro w'amashanyarazi cyangwa hakoreshejwe modulator y'urumuri kugira ngo ihindure vuba umuvuduko w'urumuri. Ubugari bw'umurongo bukoreshwa mu bindi bihe. Ubugari bw'umurongo bukoreshwa kandi mu gusobanura ubugari bw'igabanuka ry'urumuri
