Ikoreshwa rya tekinoroji yaamashanyarazi ya optique

Umuyoboro wa Electro-optique （Moderi ya EOM） Ni ikimenyetso cyo kugenzura ibimenyetso bikoresha ingufu za electro-optique kugirango uhindure urumuri. Ihame ryakazi ryarwo muri rusange rigerwaho binyuze mubikorwa bya Pockels (Ingaruka ya Pockels, aribyo Pockels effect), ikoresha inyungu yibintu byerekana ko indangantego yo kwangirika yibikoresho bya optique bidafite umurongo bihinduka mubikorwa byumuriro wamashanyarazi.

Imiterere yibanze ya moderi ya electro-optique isanzwe ikubiyemo kristu (Pockels kristal) ifite ingufu za electro-optique, kandi ibintu bisanzwe ni lithium niobate (LiNbO₃). Umuvuduko usabwa kugirango uhindure icyiciro cyitwa Half-wave voltage. Kuri kristu ya Pockels, amagana cyangwa ibihumbi bya volt mubisanzwe birasabwa, bityo hakenerwa ingufu za voltage nyinshi. Inzira ya elegitoroniki ikwiye irashobora guhindura voltage ndende muri nanosekondi nkeya, bigatuma EOM ikoreshwa nka optique yihuta; Bitewe na capacitif ya kristu ya Pockels, aba bashoferi bakeneye gutanga umubare utari muto wubu (mugihe cyo guhinduranya byihuse cyangwa guhinduka, ubushobozi bugomba kugabanuka kugirango igabanye ingufu). Mubindi bihe, nkigihe bisabwa gusa amplitude cyangwa icyiciro cya modulasiyo isabwa, gusa voltage ntoya irakenewe kugirango modulasiyo. Ibindi bikoresho bidafite umurongo wa kirisiti ikoreshwa muri electro-optique modulator (Moderi ya EOM) ushizemo potasiyumu titanate (KTP), beta-barium borate (BBO, ikwiranye nimbaraga zisanzwe zingana na / cyangwa inshuro nyinshi zo guhinduranya), lithium tantalate (LiTaO3), na fosifati ya amonium (NH4H2PO4, ADP, hamwe na electro-optique).

Abayobora amashanyarazi optModeri ya EO） Kwerekana imbaraga zingenzi zishobora gukoreshwa mubice byinshi byubuhanga buhanitse:

1.Moderi ya EOByakoreshejwe muguhindura ibimenyetso bya optique, kwemeza amakuru neza kandi yizewe yoherejwe kure. Mugucunga neza icyiciro cyangwa amplitude yumucyo, umuvuduko mwinshi hamwe nubushobozi bunini bwo kohereza amakuru birashobora kugerwaho.

2. Precision spectroscopy: Moderi ya electro-optique ihindura isoko yumucyo muri spekrometero kugirango irusheho gupima neza. Muguhindura byihuse inshuro cyangwa icyiciro cyibimenyetso bya optique, gusesengura no kumenya ibice bigize imiti bigoye birashobora gushyigikirwa, kandi gukemura no kumva neza ibipimo byerekana bishobora kunozwa.

3. Gutunganya amakuru meza cyane yo gutunganya amakuru: moderi ya electro-optique muri optique yo kubara no gutunganya amakuru, binyuze mugihe nyacyo cyo guhindura ibimenyetso bya optique kugirango tunoze amakuru yihuse kandi byoroshye. Hamwe nigisubizo cyihuse kiranga EOM, umuvuduko mwinshi hamwe nubukererwe buke optique yo gutunganya no kohereza birashobora kugerwaho.

4. Muguhindura neza ibipimo byumurongo wa laser, gutunganya ubuziranenge bwa laser birashobora kugerwaho.
