I-LPT-11 I-Serial Experiments ku-Semiconductor Laser

Incazelo

I-laser ngokuvamile iqukethe izingxenye ezintathu
(1) I-Laser yokusebenza medium
Ukukhiqizwa kwe-laser kufanele kukhethe indlela yokusebenza efanele, okungaba igesi, uketshezi, okuqinile noma i-semiconductor.Kulolu hlobo lwe-medium, ukuguqulwa kwenani lezinhlayiya kungenziwa, okuyisimo esidingekayo sokuthola i-laser.Ngokusobala, ukuba khona kwezinga le-metastable energy kunenzuzo enkulu ekugcwalisekeni kokuguqulwa kwenombolo.Njengamanje, cishe kunezinhlobo eziyi-1000 zemidiya esebenzayo, engakhiqiza ububanzi obuhlukahlukene be-laser wavelengths ukusuka ku-VUV kuye kude kude ne-infrared.
(2) Umthombo wokukhuthaza
Ukuze wenze ukuguqulwa kwenani lezinhlayiya kuvele endaweni yokusebenza, kuyadingeka ukusebenzisa izindlela ezithile ukuze ujabule uhlelo lwe-athomu ukwandisa inani lezinhlayiya ezingeni eliphezulu.Ngokuvamile, ukukhishwa kwegesi kungasetshenziswa ukujabulisa ama-athomu e-dielectric ngama-electron anamandla e-kinetic, okubizwa ngokuthi i-excitation kagesi;umthombo wokukhanya we-pulse ungasetshenziswa futhi ukukhanyisela i-work medium, ebizwa ngokuthi i-optical excitation;i-thermal excitation, i-chemical excitation, njll. Izindlela ezihlukahlukene zokuvusa zibonwa njengepompo noma ipompo.Ukuze uthole ukukhishwa kwe-laser ngokuqhubekayo, kuyadingeka ukupompa ngokuqhubekayo ukugcina inani lezinhlayiya ezingeni eliphezulu ngaphezu kwalelo elisezingeni eliphansi.
(3) Isikhala esinomsindo
Ngomthombo osebenzayo osebenzayo kanye nomthombo wokuvusa, ukuguqulwa kwenombolo yezinhlayiyana kungenziwa, kodwa ukuqina kwemisebe evuselelwe kubuthakathaka kakhulu, ngakho-ke ngeke kusetshenziswe ekusebenzeni.Ngakho-ke abantu bacabanga ukusebenzisa i-optical resonator ukuze bakhulise.I-resonator ebizwa ngokuthi i-optical resonator empeleni iyizibuko ezimbili ezinokubonakala okuphezulu okufakwe ubuso nobuso kuzo zombili iziphetho ze-laser.Enye cishe iwukubonakaliswa okuphelele, enye ibonakala kakhulu futhi idluliswa kancane, ukuze i-laser ikhishwe ngesibuko.Ukukhanya okubonakala emuva endaweni yokusebenza kuyaqhubeka nokuheha imisebe emisha evuselelwe, nokukhanya kuyakhuliswa.Ngakho-ke, ukukhanya kuzungeza emuva naphambili ku-resonator, kubangele ukusabela kweketango, okukhuliswa njenge-avalanche, okukhiqiza ukuphuma kwe-laser okuqinile kusukela ekugcineni kwesibuko esibukweni esiyingxenye.
