Ihame rya tuning ya semiconductor laser (Tunable laser)

Guhuza ihame ryaUmuyoboro wa semiconductor laser(Lazeri ihindagurika)

Umuyoboro wa semiconductor laser ni ubwoko bwa lazeri ishobora guhora ihindura uburebure bwumurongo wa laser isohoka murwego runaka. Ihinduramiterere ya semiconductor laser ikoresha uburyo bwo guhuza ubushyuhe, guhuza amashanyarazi no guhuza imashini kugirango uhindure uburebure bwurwobo, urusobekerane rwerekana ibintu, icyiciro nizindi mpinduka kugirango ugere kumurongo wizuba. Ubu bwoko bwa lazeri bufite uburyo bwinshi bwo gukoresha mu itumanaho rya optique, spekitroscopi, sensing, ubuvuzi nizindi nzego. Igishushanyo 1 kirerekana ibice shingiro bya alaser, harimo urumuri rwunguka urumuri, FP cavity igizwe nindorerwamo zimbere ninyuma, hamwe nuburyo bwo guhitamo uburyo bwo guhitamo. Hanyuma, muguhindura uburebure bwikigaragaza, optique yuburyo bwa filteri irashobora kugera kumurongo wo guhitamo.

Uburyo bwo guhuza no kubikomokaho

Ihame ryo guhuza nezaicyuma gikoreshaahanini biterwa no guhindura ibipimo bifatika bya laser resonator kugirango ugere kumahinduka ahoraho cyangwa yihariye mubisohoka laser wavelength. Ibipimo birimo, ariko ntibigarukira gusa, indangantege, uburebure bwa cavity, nuburyo bwo guhitamo. Ibikurikira birambuye uburyo bwinshi bwo guhuza hamwe namahame yabo:

1. Gutera inshinge

Gutwara inshinge zitwara abagenzi ni uguhindura indangagaciro yo kugabanya ibintu uhindura umuyaga winjiye mukarere gakora ka lazeri ya semiconductor, kugirango ugere kumurongo wizuba. Iyo ikigezweho cyiyongereye, ubwikorezi bwabatwara mukarere gakora bwiyongera, bikavamo ihinduka ryibipimo byangirika, ari nako bigira ingaruka kumuraba wa laser.

. Imihindagurikire yubushyuhe igira ingaruka ku bipimo byangirika nubunini bwibintu.

3. Guhuza imashini Gukora imashini ni ukugera kumurongo woguhindura uhindura umwanya cyangwa Inguni yibintu byo hanze bya optique ya laser. Uburyo bukoreshwa muburyo bwa tekinike burimo guhindura Inguni ya diffraction grating no kwimura umwanya windorerwamo.

4 Guhuza amashanyarazi-optique Guhuza amashanyarazi bigerwaho mugukoresha umurima wamashanyarazi kubikoresho bya semiconductor kugirango uhindure indangagaciro zivunagura ryibikoresho, bityo ugere kumurongo wizuba. Ubu buryo bukoreshwa muriamashanyarazi ya optique (EOM) na electro-optique yatunganijwe.

Muncamake, ihame rya tuning ya semiconductor laser irashobora kumenya cyane cyane uburebure bwumurongo uhindura ibipimo bifatika bya resonator. Ibipimo birimo indangagaciro zivunika, uburebure bwa cavity, nuburyo bwo guhitamo. Uburyo bwihariye bwo gutunganya harimo gutera inshinge zitwara abagenzi, guhuza ubushyuhe, guhuza imashini no guhuza amashanyarazi. Buri buryo bugira uburyo bwihariye bwumubiri nuburyo bukomoka ku mibare, kandi guhitamo uburyo bukwiye bwo guhuza bigomba gukenera gusuzumwa ukurikije ibisabwa byihariye bisabwa, nko guhuza intera, guhuza umuvuduko, gukemura no gutuza.
