"Inhliziyo" ye-laser: gainmedium
In ubuchwepheshe be-laser, ii-laser gainmedium(eyaziwa nangokuthi i-active medium noma i-laser working substance) iyisakhi esiyinhloko salei-laser. Ifinyelela ukuguqulwa kwenombolo yezinhlayiya ngokupompa, inikeza ikhono lokukhulisa ukukhanya, ikhokhela ukulahlekelwa emgodini we-resonant, futhi ngaleyo ndlela ikhiqize umphumela we-laser oqondile. Ngaphandle kwe-gain medium efanelekile, bekungeke kube khona i-laser esebenza kahle.
1. Umqondo oyisisekelo kanye nesimiso sokusebenza semidiya yokuthola inzuzo.
Umsebenzi we-gain media ukukhulisa amandla okukhanya ngokukhipha umoya okushukumisayo. Ngokuvamile, ukupompa kwangaphandle (ukupompa okukhanya noma ukupompa kagesi) kuyadingeka ukuze kutholakale amandla okuguqula amandla ezinhlayiya ezisezingeni eliphezulu.
2. Izidingo zemidiya yokuzuza okuhle kakhulu:
Akuzona zonke izinto ezingasetshenziswa njengemidiya yokuthola amandla. Izidingo Eziyinhloko: Ushintsho lwe-Laser: Kukhona i-cross-section enamandla yokukhipha (o_em) ebangeni le-wavelength eliqondiwe. Ukukhanya okuphezulu: Izinto zomsingathi zibonakala kuma-wavelength e-laser kanye ne-pump. Ukumuncwa kwephampu okusebenzayo: Ukuqondanisa umthombo wephampu otholakalayo (njengokumpompa kwe-LD okungu-808 nm Nd:YAG) kufanelekile empilweni yezinga eliphezulu (T): Isikhathi eside sizuzisa ekushintsheni kwe-Q, isikhathi esifushane sizuzisa ekushintsheni amandla. Ukusebenza kahle kwe-quantum ephezulu: Ukucima okuphansi, ukumuncwa kwesimo esiphansi esijabulisayo. Umkhiqizo we-o·T ophezulu: Ukufinyelela inzuzo ephezulu kanye nomkhawulo ophansi. I-wide gain bandwidth: Izuzisa ekulungiseni ubude be-wavelength kanye nama-pulse amafushane kakhulu. Izakhiwo zokushisa nezomshini: Ukuqhuba okuphezulu kokushisa, i-thermo-optic coefficient ephansi, umkhawulo womonakalo ophezulu. Ezinye: Ukuzinza kwamakhemikhali, ukungabikho kwe-hygroscopicity, umkhawulo womonakalo ophezulu. Lezi zidingo zivame ukungqubuzana. Isibonelo, i-wideband ebanzi ivame ukusho i-cross-section ephansi, futhi lokhu kudinga ukuhwebelana ezimweni zohlelo lokusebenza.
I-gain medium iyisici esibalulekile se-ukusebenza kwe-laserKusukela ku-Nd:YAG yakudala kuya ku-fiber optical enamandla amakhulu yesimanje, intuthuko ezintweni zokwakha iye yandisa ukusetshenziswa kwama-laser ngokuqhubekayo. Ekwakhiweni okusebenzayo, ukulingisa ngezinombolo kuvame ukudingeka ukuze kuthuthukiswe amazinga okusebenzisa izidakamizwa, izinhlelo zokupompa, njll.
