Ka'idar daidaitawaLaser semiconductor mai iya daidaitawa(Lasisar da za a iya gyarawa)

Laser mai daidaitawa na semiconductor wani nau'in laser ne wanda zai iya ci gaba da canza tsawon fitowar laser a cikin wani takamaiman kewayon. Laser mai daidaitawa na semiconductor yana amfani da daidaitawar zafi, daidaitawar lantarki da daidaitawar injiniya don daidaita tsawon ramin, bakan nuni na grating, lokaci da sauran masu canji don cimma daidaitawar tsawon tsayi. Wannan nau'in laser yana da aikace-aikace iri-iri a cikin sadarwa ta gani, spectroscopy, sensing, likita da sauran fannoni. Hoto na 1 yana nuna ainihin abun da ke ciki nalaser mai iya canzawa, gami da na'urar samun haske, ramin FP wanda ya ƙunshi madubai na gaba da na baya, da kuma na'urar zaɓin yanayin gani. A ƙarshe, ta hanyar daidaita tsawon ramin gani, matattarar yanayin gani na iya kaiwa ga fitowar zaɓin tsawon tsayi.

Ka'idar gyarawa ta mai gyarawaLasers na semiconductorgalibi ya dogara ne akan canza sigogin zahiri na resonator na laser don cimma canje-canje masu ci gaba ko na daban a cikin tsawon laser na fitarwa. Waɗannan sigogin sun haɗa da, amma ba'a iyakance ga ba, ma'aunin haske, tsawon rami, da zaɓin yanayi. Ga wasu cikakkun bayanai game da hanyoyin daidaitawa da yawa da ƙa'idodin su:

1. Daidaita allurar jigilar kaya

Daidaita allurar ɗaukar kaya shine don canza ma'aunin refractive na kayan ta hanyar canza wutar da aka saka zuwa yankin aiki na laser semiconductor, don cimma daidaiton tsawon rai. Lokacin da wutar ta ƙaru, yawan mai ɗaukar kaya a yankin aiki yana ƙaruwa, wanda ke haifar da canji a ma'aunin refractive, wanda hakan ke shafar tsawon laser.

2. Daidaitawar Zafi Daidaitawar Zafi shine canza ma'aunin haske da tsawon ramin kayan ta hanyar canza zafin aiki na laser, don cimma daidaiton tsayin tsayi. Canje-canje a zafin jiki yana shafar ma'aunin haske da girman kayan.

3. Gyaran Inji Gyaran inji shine don cimma daidaitawar tsawon tsayi ta hanyar canza matsayi ko kusurwar abubuwan gani na waje na laser. Hanyoyin gyara injina na yau da kullun sun haɗa da canza kusurwar grating ɗin diffraction da motsa matsayin madubi.

4 Gyaran Electro-optical Ana samun daidaitawar Electro-optical ta hanyar amfani da filin lantarki a kan kayan semiconductor don canza ma'aunin haske na kayan, ta haka ne ake cimma daidaitawar tsawon rai. Wannan hanyar ana amfani da ita sosai a cikinmasu daidaita wutar lantarki (EOM) da kuma na'urorin laser masu daidaita hasken lantarki.

A taƙaice, ƙa'idar gyarawa ta laser semiconductor mai iya gyarawa galibi tana gano daidaita tsawon tsayi ta hanyar canza sigogin zahiri na resonator. Waɗannan sigogi sun haɗa da ma'aunin refractive, tsawon rami, da zaɓin yanayi. Takamaiman hanyoyin gyarawa sun haɗa da daidaita allurar ɗaukar kaya, daidaita zafi, daidaita injina da daidaita electro-optical. Kowace hanya tana da nata takamaiman tsarin jiki da kuma samowar lissafi, kuma zaɓin hanyar daidaitawar da ta dace yana buƙatar la'akari da takamaiman buƙatun aikace-aikacen, kamar kewayon daidaitawa, saurin daidaitawa, ƙuduri da kwanciyar hankali.
