Ukuhlolwa kwe-LPT-11 Serial ku-Semiconductor Laser

Incazelo

Ngokulinganisa amandla, i-voltage namandla wamanje we-semiconductor laser, abafundi bangaqonda ukusebenza kwezimpawu zelaser semiconductor ngaphansi kokukhipha okuqhubekayo. I-Optical multichannel analyzer isetshenziselwa ukubona ukuphuma kwe-fluorescence ye-semiconductor laser lapho i-injection yamanje ingaphansi kwenani lomkhawulo kanye nokuguqulwa komugqa we-spectral we-laser oscillation lapho i-current inkulu kune-threshold yamanje.

I-Laser ngokuvamile iqukethe izingxenye ezintathu
(1) Laser ukusebenza naphakathi
Isizukulwane se-laser kufanele sikhethe indawo yokusebenza efanelekile, okungaba yigesi, uketshezi, okuqinile noma i-semiconductor. Kulolu hlobo lwendawo, ukuguqulwa kwenombolo yezinhlayiya kungabonakala, okuyisimo esidingekayo sokuthola i-laser. Ngokusobala, ukuba khona kwezinga lamandla eliguqukayo kuzuzisa kakhulu ekufezekisweni kwenombolo yokuguqulwa. Njengamanje, kunezinhlobo ezicishe zibe yi-1000 zemidiya esebenzayo, engakhiqiza anhlobonhlobo ama-wavelengths e-laser kusuka ku-VUV kuya kwi-infrared ekude.
(2) Umthombo wokukhuthaza
Ukuze kwenziwe ukuguqulwa kwenombolo yezinhlayiya endaweni yokusebenza, kuyadingeka ukusebenzisa izindlela ezithile ukujabulisa uhlelo lwe-athomu ukukhulisa inani lezinhlayiya ezingeni eliphezulu. Ngokuvamile, ukukhishwa kwegesi kungasetshenziselwa ukujabulisa ama-athomu we-dielectric ngama-electron ane-kinetic energy, okubizwa ngokuthi yi-excitation kagesi; Umthombo wokukhanya kwe-pulse ungasetshenziselwa ukukhanyisa indawo yokusebenza esebenzayo, ebizwa nge-excitation optical; ukukhuthazeka okushisayo, ukukhuthazeka kwamakhemikhali, njll. Izindlela ezahlukahlukene zokuthakazelisa zibonakala njengepompo noma ipompo. Ukuze uthole ukukhishwa kwe-laser ngokuqhubekayo, kuyadingeka ukuthi upompe ngokuqhubekayo ukugcina inani lezinhlayiya ezingeni eliphezulu ngaphezu kwalelo elisezingeni eliphansi.
(3) umgodi Resonant
Ngomthombo osebenzayo ofanele nomthombo wokuthakazelisa, ukuguqulwa kwenombolo yezinhlayiyana kungabonakala, kepha amandla emisebe evuselelwe abuthakathaka kakhulu, ngakho-ke ngeke isetshenziswe lapho kwenziwa. Ngakho-ke abantu bacabanga ukusebenzisa i-resonator ebonakalayo ukukhulisa. Okubizwa nge-optical resonator empeleni kuyizibuko ezimbili ezine-reflectivity ephezulu efakwe ubuso nobuso emaphethelweni womabili e-laser. Okunye kucishe kubonakaliswe ngokuphelele, okunye kubonakala kakhulu futhi kudluliswa kancane, ukuze i-laser ikwazi ukukhishwa esibukweni. Ukukhanya kubonakalise emuva ekusebenzeni okuqhubekayo kuyaqhubeka nokukhipha imisebe emisha evuselelwe, futhi ukukhanya kukhulisiwe. Ngakho-ke, ukukhanya kuyazulazula ngapha nangapha ku-resonator, kubangele ukusabela kwamaketanga, okukhuliswa njenge-avalanche, kukhiqize ukukhishwa okuqinile kwe-laser kusuka kolunye uhlangothi lwesibuko esikhanyayo.
