Pfupiso yesimba gurulaser ye semiconductorbudiriro chikamu chechipiri
Laser yefaibha.
Malaser efiber anopa nzira isingadhuri yekushandura kupenya kwemalaser e semiconductor ane simba guru. Kunyangwe mawavelength multiplexing optics achigona kushandura malaser e semiconductor ane kupenya kwakaderera kuita akajeka, izvi zvinokonzerwa nekuwedzera kwehupamhi hwespectral uye kuomarara kwe photomechanical. Malaser efiber aratidza kuti anoshanda zvakanyanya mukushandura kupenya.
Mafiber ane double-clad akaunzwa muma1990, achishandisa single-mode core yakakomberedzwa ne multimode cladding, anogona kupinza zvinobudirira multimode semiconductor pump lasers ine simba rakakwirira, inodhura zvishoma mu fiber, zvichigadzira nzira inodhura zvishoma yekushandura high-power semiconductor lasers kuita manyuko echiedza akajeka. Kune ytterbium-doped (Yb) fibers, pombi iyi inokurudzira bhendi reabsorption rakafara riri pa 915nm, kana bhendi reabsorption rakamanikana riri pedyo ne 976nm. Sezvo wavelength yekupomba ichisvika pawavelength ye lasing ye fiber laser, inonzi quantum deficit inodzikira, zvichiita kuti kushanda zvakanaka kuwedzere uye kuderedza huwandu hwekupisa kwemarara hunofanira kubviswa.
Malaser efaibhauye ma-diode-pumped solid-state lasers ese anovimba nekuwedzera kwekupenya kwelaser ye diodeKazhinji, sezvo kupenya kwema diode lasers kuchiramba kuchikwira, simba rema lasers avanopomba rinowedzerawo. Kuvandudzwa kwekupenya kwema semiconductor lasers kunowanzo kurudzira kushandurwa kwekupenya kunoshanda zvakanyanya.
Sezvatinotarisira, kupenya kwenzvimbo uye kwespectral kuchave kwakakosha kune masisitimu emangwana ayo achagonesa kupomba kwe quantum deficit yakaderera kuti zvinhu zvinyatso shandiswa mu solid-state lasers, pamwe nezvirongwa zvekushandisazve dense wavelength zvakare pakushandisa zvakananga semiconductor laser.

Musika uye mashandisirwo
Kufambira mberi muma laser e semiconductor ane simba guru kwakaita kuti zvikwanisike kushandisa zvinhu zvakawanda zvakakosha. Sezvo mutengo we watt yekupenya kwe ma laser e semiconductor ane simba guru wadzikira zvakanyanya, ma laser aya anotsiva matekinoroji ekare uye anogonesa mhando itsva dzezvigadzirwa.
Nekuvandudzika kwemitengo uye mashandiro emagetsi kanopfuura kagumi mumakore gumi ega ega, ma laser e semiconductor ane simba guru akakanganisa musika nenzira dzisingatarisirwi. Kunyange zvazvo zvakaoma kufanotaura mashandisirwo emangwana nemazvo, zvinodzidzisawo kutarisa kumashure mumakore makumi matatu apfuura kuti ufungidzire mikana yemakore gumi anotevera (ona Mufananidzo 2).
Hall paakaratidza ma semiconductor lasers makore anopfuura makumi mashanu apfuura, akatanga shanduko yetekinoroji. Kufanana naMoore's Law, hapana aigona kufanotaura kubudirira kukuru kwema semiconductor lasers ane simba guru kwakazotevera nekuvandudzwa kwakasiyana-siyana.
Remangwana rema semiconductor lasers
Hakuna mitemo mikuru yefizikisi inodzora kuvandudzwa uku, asi kufambira mberi kwetekinoroji kunogona kuramba kuripo mukubudirira uku kukuru. Malaser eSemiconductor acharamba achitsiva matekinoroji echinyakare uye achachinja zvakanyanya magadzirirwo ezvinhu. Chinonyanya kukosha pakukura kwehupfumi, malaser e semiconductor ane simba guru achachinjawo zvinogona kugadzirwa.
