Ikoreshwa rya tekinoroji ya laser

Nikimoderiikoranabuhanga

Umucyo ni ubwoko bwa electromagnetic wave hamwe numurongo mwinshi. Ifite ubwuzuzanye buhebuje bityo, nkumurongo wa elegitoroniki ya elegitoroniki (nka radiyo na tereviziyo), urashobora gukoreshwa nkuwitwara mugutanga amakuru. Amakuru "yatwawe" na lazeri (harimo ururimi, inyandiko, amashusho, ibimenyetso, nibindi) byoherezwa kubakira binyuze mumiyoboro imwe yohereza (ikirere, fibre optique, nibindi), hanyuma ikamenyekana kandi igasubizwa kumakuru yumwimerere nuwakira optique. Inzira yo gupakira amakuru kuri laser yitwa modulation, kandi igikoresho gisohoza iki gikorwa cyitwa modulator. Muri byo, laser yitwa umuyaga utwara; Amakuru make-yamakuru afite uruhare rwo kugenzura yitwa ikimenyetso cyahinduwe.

Moderi ya moderi irashobora kugabanywa muburyo bwimbere no guhinduranya hanze.

Guhindura imbere: Byerekeza ku gupakira ibimenyetso byahinduwe mugihe cya lazeri ihindagurika, ni ukuvuga, gukoresha ibimenyetso byahinduwe kugirango uhindure ibipimo bya oscillation ya lazeri, bityo uhindure ibiranga lazeri kugirango ugere kubihinduka. Uburyo bwo guhinduranya imbere harimo: 1. Kugenzura mu buryo butaziguye amashanyarazi ya pompe kugirango ugere ku mbaraga zahinduwe na laser. Imbaraga no kuboneka ibisohoka byose bigenzurwa namashanyarazi. Niba ikimenyetso cyoherezwa gikoreshwa mugucunga amashanyarazi ya laser, guhindura impinduka zubu binyuze muri laser igenzurwa nikimenyetso, noneho lazeri yasohotse nayo izagenzurwa nikimenyetso. 2. Ibyiza byo guhinduranya imbere ni imikorere yacyo yo hejuru. Ingaruka ni uko kuva modulator yashyizwe imbere mu cyuho, bihwanye no kongera igihombo imbere mu cyuho, kugabanya ingufu zisohoka, kandi umurongo wa modulator ugarukira ku murongo wa passant ya resonant cavity.

Guhinduranya hanze: Bivuga gushyira modulator kumuhanda wa optique hanze ya lazeri nyuma ya lazeri imaze gukorwa, kandi ibimenyetso biranga modulator bihindurwa nikimenyetso cyo guhindura. Iyo lazeri inyuze muri modulator, ikintu runaka cyumucyo uzahinduka. Ibyiza byo guhinduranya hanze ni uko bidahindura imbaraga zisohoka za laser kandi umurongo wa generator ntugarukira kuri passband ya resonant cavity. Ingaruka nuburyo buke bwo guhindura imikorere.

Ihindurwa rya Laser rishobora gushyirwa muburyo bwo guhinduranya amplitude, guhinduranya inshuro, guhinduranya icyiciro no guhinduranya imbaraga, nibindi ukurikije imiterere yabyo. Guhuza modulator isanzwe irimoicyiciro, modulator, nibindi.moderi, nka transversamashanyarazi ya electro-optique, moderi ya electro-optique yingendo, moderi ya Kerr electro-optique, moderi ya acousto-optique, modulatori ya magneto-optique, modulatrice yivanga hamwe na moderi yumucyo uri ahantu, nibindi.
