Umgomo we-Semiconductor Laser (I-Annoble Laser)

Umthetho wokushintsha weI-Tenoble semiconductor laser(I-ANONble Laser)

I-Tenoble semiconductor Laser uhlobo lwe-laser olungashintsha ngokuqhubekayo i-wavelength yokukhipha ama-laser ebangeni elithile. I-Temuble Semiconductor Laser yamukela ukuguqulwa kwe-Thermal, ukuhlela kagesi kanye nokuhleleka kwemishini ukulungisa ubude be-cavity, i-grating reffection spectrum, isigaba kanye nezinye izinto eziguquguqukayo ukufeza ukuguquguquka kwe-wavengeth. Lolu hlobo lwe-laser lunezinhlobonhlobo zezicelo ekuxhumaneni okubonakalayo, i-spectroscopy, ukuzwela, ezokwelapha kanye nezinye izinkambu. Umdwebo 1 ukhombisa ukwakheka okuyisisekelo kweI-Laser ye-Tunble, kufaka phakathi iyunithi yokuthola inzuzo yokukhanya, i-fp cavity eyakhiwe ngezibuko ezingaphambili nezingemuva, kanye neyunithi yokukhetha imodi yokukhetha iModi. Ekugcineni, ngokulungisa ubude be-cavity ekhanyayo, isihlungi semodi yokubona singafinyelela okukhipha ikhefu.

Indlela yokuguqula nokususwa kwayo

Umgomo wokuhleka we-tunAma-Semiconductor LasersKakhulu kuncike ekushintsheni kwamapharamitha angokomzimba we-laser resonator ukufezekisa izinguquko eziqhubekayo noma ezi-discrete endaweni yokuphuma ye-laser wavelth. Lezi zinhlaka zifaka, kepha azikhawulwanga, inkomba eyeqa kabusha, ubude be-cavity, kanye nokukhethwa kwemodi. Imininingwane elandelayo izindlela ezivamile zokuhlelwa kwezimpawu nemigomo yazo:

1. Ukuhleleka komjovo wenethiwekhi

Ukuhlelwa komjovo we-Carriers ukushintsha inkomba evulekayo yokwenziwa ngokushintsha okufakwayo kwamanje esifundeni esisebenzayo se-semiconductor laser, ukuze kufinyelelwe ebukhosini be-wavewthth. Lapho ukwenyuka kwamanje, ukugxila kwenkampani yenethiwekhi esifundeni esisebenzayo kukhuphuka, okuholela ekushintsheni kwenkomba eyesiko, nakho okuthinta i-laser wavelength.

2 Izinguquko zokushisa zithinta inkomba eyevusayo nosayizi womzimba wezinto ezibonakalayo.

I-3 Izindlela ezijwayelekile zokuhlelwa kwemishini zifaka ukuguqula i-angle yokwehlukahlukana nokuhambisa isikhundla sesibuko.

I-Electro-Optimity Tuning Electro-Optimical ifinyelelwa ngokusebenzisa inkambu kagesi kwizinto ezisetshenziswayo ze-semiconductor ukushintsha inkomba yokuphinda yalokho, ngaleyo ndlela kufinyelelwe i-wavengeth tuning. Le ndlela ivame ukusetshenziswaI-Electro-Optical Modulators (Xothi) kanye ne-electro-special tuned lasers.

Ngamafuphi, umgomo wokuhlwitha we-semiconductor laser usebenzisa i-wavelength eshintsha ngokushintsha amapharamitha angokomzimba we-resonator. Lawa mapharamitha afaka inkomba eyeqanayo, ubude be-cavity, kanye nokukhethwa kwemodi. Izindlela ezithile zokuhlenga zifaka phakathi ukufakwa komjovo wenethiwekhi, ukuhleleka okushisayo, ukuhleleka kwemishini nokuhleleka kwe-electro-optical. Indlela ngayinye inendlela yayo ekhethekile yomzimba kanye nokususwa kwezibalo, kanye nokukhethwa kwendlela efanele yokuhlekisa kudinga ukubhekwa ngokuya ngezidingo ezithile zesicelo, ijubane lokuhlekisa, ukulungiswa nokuqina.
