I-LPT-11 Uthotho lwamaMfuniselo kwi-Semiconductor Laser oFanelekileyo loMfanekiso

LPT-11 Uthotho lweMfuniselo kwiSemiconductor Laser

Inkcazelo emfutshane:

Ngokulinganisa amandla, i-voltage kunye ne-laser ye-semiconductor yangoku, abafundi banokuqonda iimpawu zokusebenza ze-laser semiconductor phantsi kwemveliso eqhubekayo.I-Optical multichannel analyzer isetyenziselwa ukujonga ukukhutshwa kwe-fluorescence ye-laser ye-semiconductor xa i-injection yangoku ingaphantsi kwexabiso le-threshold kunye nokuguqulwa komgca we-spectral we-laser oscillation xa ikhoyo inkulu kunomda wangoku.

Inkcazo

I-Laser ngokubanzi inamacandelo amathathu
(1) Isixhobo sokusebenza seLaser
Ukuveliswa kwe-laser kufuneka kukhethe i-medium efanelekileyo yokusebenza, enokuba yigesi, ulwelo, eqinile okanye i-semiconductor.Kulo hlobo oluphakathi, ukuguqulwa kwenani leengqungquthela kunokufezekiswa, okuyimeko efunekayo yokufumana i-laser.Ngokucacileyo, ubukho benqanaba lamandla e-metastable luncedo kakhulu ekuphunyezweni kwenani lokuguqulwa.Okwangoku, kukho malunga ne-1000 yeentlobo zemidiya esebenzayo, enokuvelisa uluhlu olubanzi lwamaza e-laser ukusuka kwi-VUV ukuya kwi-infrared ekude.
(2) Umthombo wenkuthazo
Ukuze wenze ukuguqulwa kwenani leengqungquthela kubonakale kwindawo yokusebenza, kuyimfuneko ukusebenzisa iindlela ezithile zokuvuselela inkqubo ye-athomu ukunyusa inani leengqungquthela kwinqanaba eliphezulu.Ngokuqhelekileyo, ukukhutshwa kwegesi kungasetyenziselwa ukuvuyisa ii-athomu ze-dielectric ngama-electron anamandla e-kinetic, okubizwa ngokuba yi-excitation yombane;umthombo wokukhanya we-pulse unokusetyenziswa kwakhona kwi-irradiate medium medium, ebizwa ngokuba yi-optical excitation;ukuvuselela i-thermal, ukuvuselela iikhemikhali, njl. Iindlela ezahlukeneyo zokuvuselela zibonwa njengempompo okanye impompo.Ukuze ufumane i-laser output ngokuqhubekayo, kuyimfuneko ukupompa ngokuqhubekayo ukugcina inani leengqungquthela kwinqanaba eliphezulu ngaphezu kwelo lisezantsi.
(3) Umngxuma ophumayo
Ngezinto zokusebenza ezifanelekileyo kunye nomthombo wokuvuselela, ukuguqulwa kwenombolo ye-particle inokuphunyezwa, kodwa ubuninzi be-radiation evuselelweyo bubuthathaka kakhulu, ngoko ayikwazi ukusetyenziswa ekusebenzeni.Ke abantu bacinga ukusebenzisa i-optical resonator ukukhulisa.Into ebizwa ngokuba yi-optical resonator eneneni zizipili ezibini ezinokukhanya okuphezulu okufakwe ubuso ngobuso kuzo zombini iziphelo zelaser.Enye iphantse ibonakaliswe ngokupheleleyo, enye ibonakaliswe kakhulu kwaye idluliselwe kancinci, ukuze i-laser ikhutshwe ngesipili.Ukukhanya okubonakaliswe ngasemva kwindlela yokusebenza kuyaqhubeka ukuphembelela imitha emitsha evuselelweyo, kwaye ukukhanya kuyandiswa.Ke ngoko, ukukhanya kujikeleza ngasemva naphambili kwi-resonator, kubangele ukusabela kwekhonkco, okukhuliswe njenge-avalanche, ukuvelisa imveliso yelaser eyomeleleyo ukusuka kwelinye icala lesibuko sokubonisa.
