Iimvavanyo ze-LPT-11 ezilandelelanayo kwi-Laser ye-Semiconductor

Inkcazo

I-laser ngokubanzi inamacandelo amathathu
(1) Indlela yokusebenza nge-laser
Ukuveliswa kwelaser kufuneka kukhethe indlela yokusebenza efanelekileyo, enokuba yigesi, ulwelo, into eqinileyo okanye i-semiconductor. Kolu hlobo lwendlela yokusebenza, ukuguqulwa kwenani lamasuntswana kunokufezekiswa, nto leyo eyimfuneko ukuze kufunyanwe ilaser. Ngokucacileyo, ukubakho kwenqanaba lamandla azinzileyo kuluncedo kakhulu ekufezekisweni kokuguqulwa kwenani. Okwangoku, kukho phantse iintlobo ezili-1000 zemidiya yokusebenza, ezinokuvelisa uluhlu olubanzi lwee-wavelengths zelaser ukusuka kwi-VUV ukuya kwi-infrared ekude.
(2) Umthombo wenkuthazo
Ukuze kwenzeke ukuba kuvele ukuguquka kwenani lamasuntswana kwindawo yokusebenza, kuyimfuneko ukusebenzisa iindlela ezithile zokuvusa inkqubo yeathomu ukuze kwandiswe inani lamasuntswana kwinqanaba eliphezulu. Ngokubanzi, ukukhutshwa kwegesi kungasetyenziselwa ukuvusa ii-athomu ze-dielectric ngee-electron ezine-kinetic energy, ebizwa ngokuba yi-electrical excitation; umthombo wokukhanya kwe-pulse ungasetyenziselwa nokukhanyisa indawo yokusebenza, ebizwa ngokuba yi-optical excitation; i-thermal excitation, i-chemical excitation, njl. Iindlela ezahlukeneyo zokuvusa zibonwa njengepompo okanye ipompo. Ukuze kufumaneke i-laser output rhoqo, kuyimfuneko ukupompa rhoqo ukugcina inani lamasuntswana kwinqanaba eliphezulu lingaphezulu kunelo kwinqanaba elisezantsi.
(3) Umgodi ocacileyo
Ngezixhobo zokusebenza ezifanelekileyo kunye nomthombo wokuvuselela, ukuguqulwa kwenani leenxalenye kunokubonwa, kodwa amandla emitha evuselelweyo abuthathaka kakhulu, ngoko ke ayinakusetyenziswa ekusebenzeni. Ngoko ke abantu bacinga ngokusebenzisa i-optical resonator ukukhulisa. I-optical resonator eneneni zizipili ezimbini ezine-reflectivity ephezulu ezifakwe ubuso ngobuso kuzo zombini iziphelo ze-laser. Esinye siphantse sibe yi-reflection epheleleyo, esinye sibonakaliswa kakhulu kwaye sidluliselwa kancinci, ukuze i-laser ikhutshwe ngesipili. Ukukhanya okubuyiswe ngasemva kwindawo yokusebenza kuyaqhubeka nokukhuthaza imitha emitsha evuselelweyo, kwaye ukukhanya kuyandiswa. Ke ngoko, ukukhanya kuyajikajika ngasemva nangaphambili kwi-resonator, okubangela ukusabela kwetyathanga, okwandiswa njenge-avalanche, okuvelisa i-laser enamandla evela kwelinye icala lesipili esibukiweyo esingaphelelanga.
