Uvavanyo lwe-LPT-11 Uthotho lweLaser Semiconductor

Inkcazo

Ngokulinganisa amandla, ombane kunye nelaser ye-semiconductor laser, abafundi banokuqonda ukusebenza kwe-semiconductor laser phantsi kwemveliso eqhubekayo. I-Optical multichannel analyzer isetyenziselwa ukugcina ukukhutshwa kwe-semiconductor laser xa i-injection yangoku ingaphantsi kwexabiso lomqobo kunye nokuguqulwa komgca we-laser oscillation xa okwangoku kukhulu kunomqobo wangoku.

I-Laser ngokubanzi inamalungu amathathu
(1) Laser yokusebenza eliphakathi
Ukuveliswa kwelaser kufuneka kukhethe indawo efanelekileyo yokusebenza, enokuba yirhasi, ulwelo, iqinile okanye isemiconductor. Ngolu hlobo oluphakathi, ukuguqulwa kwenani lamasuntswana kunokufezekiswa, yimeko efanelekileyo yokufumana i-laser. Ngokucacileyo, ubukho benqanaba lamandla aguqukayo liluncedo kakhulu ekuqondeni inani lokuguqula inamba. Okwangoku, kukho phantse i-1000 leendidi zemithombo yeendaba ezisebenzayo, ezinokuvelisa uluhlu olubanzi lwee-wavevel ze-laser ukusuka kwi-VUV ukuya kwi-infrared kude.
(2) Umthombo wenkuthazo
Ukwenza ukuguqulwa kwenani lamasuntswana kubonakale kwindawo yokusebenza, kufanelekile ukusebenzisa iindlela ezithile ukonwabisa inkqubo yeatom ukwandisa inani lamasuntswana kwinqanaba eliphezulu. Ngokubanzi, ukukhutshwa kwerhasi kunokusetyenziselwa ukuvuyisa ii-atom zedielectri zii-elektroni ezinamandla e-kinetic, ebizwa ngokuba kukuzihlaziya kombane; umthombo wokukhanya kokubetha ungasetyenziselwa ukwenza i-irradiate medium medium, ebizwa ngokuba yi-optical excitation; uchulumanco thermal, excitation imichiza, njl iindlela ezahlukeneyo excitation zibonwa njenge impompo okanye impompo. Ukuze ufumane imveliso laser ngokuqhubekekayo, kuyimfuneko ukuba ukumpompa ngokuqhubekayo ukugcina inani amasuntswana kwinqanaba eliphezulu ngaphezu kokuba kwinqanaba elisezantsi.
(3) kwisisu Resonant
Ngokusebenza ngokufanelekileyo kunye nezinto ezikhuthazayo, ukuguqululwa kwenani lamasuntswana kunokufezekiswa, kodwa amandla emitha ekhuthazayo abuthathaka kakhulu, ngenxa yoko ayinakusetyenziswa xa kusenziwa. Ke abantu bacinga ngokusebenzisa i-resonator ebonakalayo ukukhulisa. I-resonator ebizwa ngokuba yi-optical resonator eneneni ziipili ezimbini ezinombonakalo ophezulu ofakelwe ubuso ngobuso kwiziphelo zombini zelaser. Inye iphantse ibonakalise iyonke, enye ibonakalisiwe kwaye ihanjiswa kancinci, ukuze i-laser ikhutshwe esipilini. Ukukhanya kubonakalise ukubuyela kumbindi osebenzayo kuyaqhubeka ukukhuthaza imitha entsha evuselelweyo, kwaye ukukhanya kuyandiswa. Ke ngoko, ukukhanya kuyashukuma uye ngapha nangapha kwi-resonator, kubangela ukusabela kwetyathanga, okwandisiweyo njenge-avalanche, ukuvelisa ukuphuma kwelaser okuqinileyo ukusuka esiphelweni sesipili.
