Mhedziso yesimba repamusorosemiconductor laserdevelopment part two
Fiber laser.
Fiber lasers inopa inodhura-inoshanda nzira yekushandura kupenya kweakakwira simba semiconductor lasers.Kunyangwe wavelength multiplexing optics inogona kushandura yakaderera-kupenya semiconductor lasers kuita inopenya, izvi zvinouya nemubhadharo wekuwedzera spectral upamhi uye photomechanical kuoma.Fiber lasers yakaratidza kuve inoshanda zvakanyanya mukushandurwa kupenya.
Mafiibha maviri-akapfeka akaunzwa muma1990s, achishandisa imwe-mode core yakakomberedzwa nemultimode cladding, inogona kunyatso kuunza yakakwirira-simba, yakaderera-inodhura multimode semiconductor pombi lasers mufayibha, ichigadzira imwe nzira inodhura yekushandura yakakwirira-simba semiconductor lasers. munzvimbo dzakajeka dzechiedza.Kune ytterbium-doped (Yb) fibers, pombi inonakidza bhendi rekunyudza rakafara iri pakati pe915nm, kana bhendi rakatetepa rekunyudza riri pedyo ne976nm.Sezvo iyo yekupomba wavelength inoswedera kune lasing wavelength yefiber laser, iyo inonzi quantum deficit inoderedzwa, kuwedzera kushanda uye kuderedza kuwanda kwemarara kupisa kunoda kubviswa.
Fiber lasersuye diode-pumped solid-state lasers zvese zvinoenderana nekuwedzera kwekupenya kweiyodiode laser.Kazhinji, sezvo kupenya kwema diode lasers kuri kuramba kuchiwedzera, simba rema lasers avanopomba rinowedzerawo.Iko kunatsiridza kupenya kwema semiconductor lasers kunowanzo kusimudzira kupenya kwakajeka kutendeuka.
Sezvatinotarisira, kupenya kwenzvimbo uye kupenya kuchave kuri madikanwa kune ramangwana masisitimu ayo anozogonesa yakaderera quantum kushomeka kupomba kune yakatetepa yekunyura maficha mune yakasimba-nyika lasers, pamwe neyakaomesesa wavelength reuse zvirongwa zveyakananga semiconductor laser application.
Mufananidzo 2: Kuwedzera kupenya kwepamusoro-simbasemiconductor lasersinobvumira kuti mapurogiramu awedzere
Musika uye kushandisa
Kufambira mberi mune yakakwirira-simba semiconductor lasers kwaita akawanda akakosha maapplication agoneke.Sezvo mutengo wekupenya kwewatt yeakakwira-simba semiconductor lasers wakaderedzwa zvakanyanya, aya lasers ese ari maviri anotsiva ekare matekinoroji uye anogonesa mitsva yechigadzirwa.
Nekudhura uye kuita zviri nani kudarika gumi-peta makore gumi ega ega, epamusoro-simba semiconductor lasers akakanganisa musika nenzira dzisingatarisirwe.Kunyange zvazvo zvakaoma kufanotaura mashandisirwo eramangwana nemazvo, zvinodzidzisawo kutarisa kumashure kwemakumi matatu emakore adarika kufungidzira zvingaitika zvemakore gumi anotevera (ona Mufananidzo 2).
Hall paakaratidza semiconductor lasers anopfuura makore makumi mashanu apfuura, akatanga shanduko yehunyanzvi.Kufanana neMutemo waMoore, hapana munhu angadai akafanotaura kubudirira kwakanakisa kwepamusoro-simba semiconductor lasers yakatevera neakasiyana siyana akasiyana.
Remangwana re semiconductor lasers
Iko hakuna mitemo yakakosha yefizikisi inodzora kuvandudzwa uku, asi kuenderera mberi kwetekinoroji kungango tsigira uku kwekukura mukubwinya.Semiconductor lasers icharamba ichitsiva echinyakare matekinoroji uye ichawedzera kushandura magadzirirwo ezvinhu.Zvinotonyanya kukosha pakukura kwehupfumi, yakakwirira-simba semiconductor lasers inoshandurawo zvinogona kugadzirwa.
