Mwachidule za Mphamvu YambiriSemiconductor lasergawo la chitukuko chimodzi

Monga mphamvu ndi mphamvu zikupitilirabe bwino,Ma daodior a laser) Idzapitilizabe kusintha matekinoloje achikhalidwe, pomangosoka momwe zinthu zimapangidwira ndi kukulitsa chitukuko cha zinthu zatsopano. Kumvetsetsa za kusintha kwakukulu kwa ma semicoctor a semicoctork kwambiri kulinso. Kutembenuka kwa ma elekitoni ku Lasers kudzera ku Semiconductors koyamba kunkachitika mu 1962, ndipo zikomo kwambiri zakwaniritsa zomwe zachitika potembenukira kwa ma elekitironi. Kupita patsogolo kumeneku kwathandiza mapulogalamu ofunikira kuchokera ku mawonedwe osungirako macheza okoma ku malo opangira mafakitale.

Kuwunikanso kwa izi ndi kupita patsogolo kwawoku kumawunikira zomwe zingatheke kwamphamvu kwambiri komanso kwakukulu m'malo ambiri achuma. M'malo mwake, posintha mosalekeza kwa ma semiconductor apamwamba kwambiri, gawo lake la ntchito litha kufulumira, ndipo zimakhudza kwambiri kukula kwachuma.

Akuluakulu okwera kwambiri a semiconduct a semiconducy a seraonducy abweretsanso chitukuko cha ukadaulo wapansi wa laser, pomwe semicondoctor a sesers amagwiritsidwa ntchito kukhwima (pampu) yolumikizidwa (pampu) yolimba-boma yolimba).

Ngakhale seractuctor Lasers amapereka mphamvu yokwanira, yaying'ono, komanso yotsika mtengo yotsika mtengo, amakhalanso ndi malire awiri ofunikira: sasunga mphamvu ndipo kuwala kwake ndi kochepa. Kwenikweni, ntchito zambiri zimafunikira ma lasers awiri othandiza; Imodzi imagwiritsidwa ntchito kusintha magetsi kukhala cholakwika cha laser, ndipo enawo amagwiritsidwa ntchito polimbikitsa kunyezimira kwakuti.

Ma Lasers Okhazikika-State.
Chakumapeto kwa zaka za m'ma 1980, kugwiritsa ntchito ma semicoctor a Senictor Lasers kuti apatuke malalanje olimba-State-Stato adayamba kupeza chidwi chachikulu pamalonda. DIODOD-PRORE PRADER-Staters (DPSL) amachepetsa kwambiri kukula ndi zovuta zamagetsi (makamaka ozungulira) ndikupeza ma morople, zomwe zidagwiritsa ntchito nyali za arc kuti ziziponda ma kristor.

Chifuwa cha semiconduct laser amasankhidwa potengera kuchuluka kwa mayamwidwe omwe ali ndi vuto lokhala ndi matebulo okhazikika poyerekeza ndi mawonekedwe a dziko lonse la nyali ya Arc. Poganizira za kutchuka kwa ma Lasers-a Ninsmium-dovers omwe akukwera 1064nm Fulllength, 808nm semiconducy laser wakhala chinthu chothandiza kwambiri mu semiconductor la nthawi yopitilira 20.

Kupukuta kwa DIOD Makhalidwe owoneka ofooka komanso opepuka pafupifupi 880nm ayambitsa chidwi kwambiri pakukhazikika pampu owoneka bwino. Ma Lasers apamwamba kwambiri awa amapangitsa kuti utsi wa nedymemium utole wa laser ya 4f3 / 2, kuchepetsa kuchepa kwamphamvu ndipo potero kukayamwa ma ampato otenthetsera.

Pofika zaka makumi angapo zapitazi za zana lino, tinali kuchitira umboni zowonjezereka zamagetsi zam'madzi za 1064nm, komanso ma laser a laseri omwe amagwira ntchito mobwerezabwereza m'manda a ultraviolet. Popeza nthawi yayitali yamphamvu ya ND: Yag ndi ND: Yvo4, Yvo4, iyi, imapangitsa kuti akhale abwino popanga makopedwe opatsa chidwi.
