LPT-11 Gwajin Serial akan Semiconductor Laser

Bayani

Ta hanyar auna ƙarfi, ƙarfin lantarki da halin yanzu na laser semiconductor, ɗalibai za su iya fahimtar halayen aikin laser lasifika ƙarƙashin ci gaba da fitarwa. Ana amfani da mai nazari na multichannel mai amfani don lura da fitowar hasken silsilar laser lokacin da allurar yanzu ba ta kai ƙimar bakin kofa da canjin layin layi na oscillation na laser ba yayin da na yanzu ya fi ƙarfin ƙofar yanzu.

Gabaɗaya Laser ya ƙunshi sassa uku
(1) Laser aiki matsakaici
Dole ne ƙarni na laser ya zaɓi matsakaicin aikin da ya dace, wanda zai iya zama gas, ruwa, mai ƙarfi ko semiconductor. A cikin irin wannan matsakaiciyar, za a iya samun canjin adadin barbashi, wanda shine yanayin da ake buƙata don samun laser. A bayyane yake, wanzuwar matakin ƙarfin makamashi mai fa'ida yana da matukar fa'ida ga fahimtar juyawar lamba. A halin yanzu, akwai kusan nau'ikan kafofin watsa labarai 1000 masu aiki, waɗanda zasu iya samar da kewayon ƙarfin laser daga VUV zuwa infrared mai nisa.
(2) Tushen ihisani
Don yin jujjuyawar adadin barbashi ya bayyana a cikin matsakaicin aiki, ya zama dole ayi amfani da wasu hanyoyi don farantawa tsarin kwayar zarra don kara yawan kwayar a matakin na sama. Gabaɗaya, za a iya amfani da fitowar gas don motsa ƙwayoyin dielectric ta hanyar electrons tare da kuzarin kuzari, wanda ake kira da motsawar lantarki; Hakanan za'a iya amfani da tushen hasken bugun jini don sanya hasken matsakaici mai aiki, wanda ake kira da motsawar gani; motsawar zafin jiki, motsawar sinadarai, da sauransu. Ana amfani da hanyoyi daban-daban na motsa jiki kamar famfo ko famfo. Don samun fitowar laser gaba ɗaya, ya zama dole a yi famfo akai-akai don kiyaye adadin barbashi a cikin matakin sama sama da na ƙananan matakin.
(3) rami mai amsa kuwwa
Tare da kayan aiki masu dacewa da tushen motsa rai, za a iya fahimtar jujjuyawar lambar barbashi, amma zafin raunin da aka kara yana da rauni sosai, saboda haka ba za a iya amfani da shi a aikace ba. Don haka mutane suna tunanin amfani da na'urar hangen nesa don fadadawa. Abinda ake kira resonator resonator shine ainihin madubin gilashi biyu tare da babban kwalliyar da aka sanya fuska don fuska a ƙarshen ƙarshen laser. Isayan kusan kusan tunani ne, ɗayan galibi ana nunawa da ɗan kaɗan, don haka ana iya fitar da laser ta cikin madubi. Hasken da yake nunawa ga matsakaiciyar mai aiki yana ci gaba da haifar da sabon iska mai motsawa, kuma hasken yana ƙaruwa. Sabili da haka, hasken yana jujjuyawa da baya a cikin resonator, yana haifar da sarkar abu, wanda aka kara shi kamar dusar ƙanƙara, yana samar da ƙarfin laser mai ƙarfi daga ƙarshen ƙarshen madubin juzu'in juzu'i.
