Ukuhlolwa Okulandelanayo kwe-LPT-11 ku-Laser ye-Semiconductor

Incazelo

I-Laser ngokuvamile inezingxenye ezintathu
(1) Indawo yokusebenza nge-laser
Ukukhiqizwa kwe-laser kumele kukhethe indawo yokusebenza efanele, okungaba yigesi, uketshezi, okuqinile noma i-semiconductor. Kulolu hlobo lwendawo, ukuguqulwa kwenani lezinhlayiya kungabonakala, okuyisimo esidingekayo ukuze kutholakale i-laser. Ngokusobala, ukuba khona kwezinga lamandla azinzile kuzuzisa kakhulu ekuqalisweni kokuguqulwa kwenani. Njengamanje, kunezinhlobo ezingaba ngu-1000 zemidiya yokusebenza, ezingakhiqiza ububanzi obukhulu bamaza e-laser kusukela ku-VUV kuya ku-infrared ekude.
(2) Umthombo wesikhuthazo
Ukuze kuvele ukuguqulwa kwenani lezinhlayiya endaweni yokusebenza, kuyadingeka ukusebenzisa izindlela ezithile zokuvusa uhlelo lwe-athomu ukuze kwandiswe inani lezinhlayiya ezingeni eliphezulu. Ngokuvamile, ukukhishwa kwegesi kungasetshenziswa ukuvusa ama-athomu e-dielectric ngama-electron anamandla e-kinetic, okubizwa ngokuthi ukuvusa ngogesi; umthombo wokukhanya kwe-pulse ungasetshenziswa futhi ukukhanyisela indawo yokusebenza, okubizwa ngokuthi ukuvusa ngokukhanya; ukuvusa ngokushisa, ukuvusa ngamakhemikhali, njll. Izindlela ezahlukene zokuvusa zibonakala njengephampu noma iphampu. Ukuze kutholakale umphumela we-laser ngokuqhubekayo, kuyadingeka ukupompa ngokuqhubekayo ukuze kugcinwe inani lezinhlayiya ezingeni eliphezulu ngaphezu kwalelo ezingeni eliphansi.
(3) Umgodi ocwebezelayo
Ngezinto zokusebenza ezifanele kanye nomthombo wokuvuselela, ukuguqulwa kwenombolo yezinhlayiya kungabonakala, kodwa amandla emisebe evuselelwe abuthakathaka kakhulu, ngakho-ke ayinakusetshenziswa ekusebenzeni. Ngakho-ke abantu bacabanga ukusebenzisa i-optical resonator ukuze ikhulise. Okubizwa ngokuthi i-optical resonator empeleni yizibuko ezimbili ezinokukhanya okuphezulu okufakwe ubuso nobuso kuzo zombili izinhlangothi ze-laser. Esinye cishe siwukukhanya okuphelele, esinye sibonakala kakhulu futhi sidluliselwa kancane, ukuze i-laser ikhishwe ngesibuko. Ukukhanya okubonakala emuva endaweni yokusebenza kuyaqhubeka nokudala imisebe emisha evuselelwe, futhi ukukhanya kuyakhuliswa. Ngakho-ke, ukukhanya kuyashintshashintsha emuva naphambili ku-resonator, okubangela ukusabela kweketanga, okukhuliswa njenge-avalanche, okukhiqiza umphumela we-laser onamandla kusuka komunye umkhawulo wesibuko sokubonakalisa okuyingxenye.

Ukuhlolwa

1. Ukucaciswa kwamandla okukhipha kwe-laser ye-semiconductor

2. Ukulinganiswa kwe-engeli ehlukene kwe-laser ye-semiconductor

3. Izinga lokulinganisa i-polarization ye-laser ye-semiconductor

4. Ukucaciswa kwe-Spectral kwe-semiconductor laser
