Mhedziso yesimba repamusorosemiconductor laserdevelopment part one
Sezvo kushanda nesimba uye simba zvichiramba zvichivandudza, laser diodes (Laser diodes mutyairi) icharamba ichitsiva matekinoroji echinyakare, nekudaro ichichinja magadzirirwo ezvinhu uye kugonesa kuvandudzwa kwezvinhu zvitsva.Kunzwisisa kwekuvandudzwa kwakakosha mu-high-simba semiconductor lasers zvakare kushoma.Shanduko yemaerekitironi kuita lasers kuburikidza nesemiconductors yakatanga kuratidzwa muna 1962, uye kwakasiyana-siyana kufambirana mberi kwakatevera uko kwave kufambisira mberi budiriro huru mukushandurwa kwemaerekitironi kuita ma lasers ane hunyanzvi.Kufambira mberi uku kwakatsigira maapplication akakosha kubva kukuchengetedza optical kune optical networking kune dzakasiyana siyana dzemaindasitiri minda.
Ongororo yekufambira mberi uku uye kufambira mberi kwadzo kunoratidza mukana wekuwedzera uye kupararira kwakanyanya munzvimbo zhinji dzehupfumi.Muchokwadi, nekuvandudzwa kunoramba kuripo kweakakwira-simba semiconductor lasers, nzvimbo yayo yekushandisa inomhanyisa kuwedzera, uye ichave nekukanganisa kukuru mukukura kwehupfumi.
Mufananidzo 1: Kuenzanisa kwekupenya uye mutemo waMoore wepamusoro simba semiconductor lasers.
Diode-pumped solid-state lasers uyefiber lasers
Kufambira mberi kwepamusoro-simba semiconductor lasers kwakonzerawo kukudziridzwa kwelaser tekinoroji, uko semiconductor lasers inowanzoshandiswa kufadza (pombi) doped crystals (diode-pumped solid-state lasers) kana doped fibers (fiber lasers).
Kunyangwe semiconductor lasers inopa inoshanda, diki, uye yakaderera-inodhura laser simba, ivo vanewo maviri akakosha maganhuriro: iwo haachengete simba uye kupenya kwawo kudiki.Chaizvoizvo, akawanda maapplication anoda maviri anobatsira lasers;Imwe inoshandiswa kushandura magetsi kuita laser emission, uye imwe inoshandiswa kuwedzera kupenya kwekubuda ikoko.
Diode-pumped solid-state lasers.
Mukupera kwema1980, kushandiswa kwema semiconductor lasers kupomba solid-state lasers kwakatanga kuwana kukosha kwekutengeserana.Diode-pumped solid-state lasers (DPSSL) inoderedza zvakanyanya saizi uye kuoma kwemasisitimu ekutonga kwemafuta (kunyanya kutenderera inotonhorera) uye kuwana mamodule, ayo akamboshandisa mwenje wearc kupomba solid-state laser makristasi.
Iyo wavelength ye semiconductor laser inosarudzwa zvichienderana nekupindirana kwe spectral absorption hunhu nekuwana yepakati yeiyo solid-state laser, iyo inogona kudzikisa zvakanyanya kupisa kwemafuta kana ichienzaniswa neyakakura emission spectrum yerambi rearc.Tichifunga nezve mukurumbira we neodymium-doped lasers emitting 1064nm wavelength, iyo 808nm semiconductor laser yave yakanyanya kugadzira chigadzirwa mu semiconductor laser kugadzirwa kweanopfuura makore makumi maviri.
Iyo yakagadziridzwa diode yekupomba inobudirira yechizvarwa chechipiri yakagoneswa nekuwedzera kupenya kwema-multi-mode semiconductor lasers uye kugona kudzikamisa yakamanikana emission linewidths uchishandisa yakawanda Bragg gratings (VBGS) pakati pe2000s.Iwo asina kusimba uye akamanikana spectral absorption maitiro akapoteredza 880nm akamutsa kufarira kukuru mune inotaridzika yakagadzikana yakakwirira kupenya kwepombi diode.Aya ma lasers epamusoro anoita kuti zvikwanisike kupomba neodymium yakananga padanho repamusoro relaser ye4F3/2, ichidzikisa kushomeka kwehuwandu uye nekudaro kuvandudza maitiro ekubvisa paavhareji simba repamusoro, iro raizoganhurwa nemalenzi ekupisa.
Pakazosvika makore gumi echipiri ezana rino remakore, takanga tichipupurira kuwedzera kukuru kwesimba mune imwechete-transverse mode 1064nm lasers, pamwe neadzo frequency conversion lasers anoshanda mune inooneka uye ultraviolet wavelengths.Tichifunga nezvehurefu hwesimba repamusoro rehupenyu hweNd: YAG uye Nd: YVO4, aya DPSSL Q-akachinjika mashandiro anopa yakakwira pulse simba uye peak simba, zvichiita kuti ive yakanakira ablative zvinhu kugadzirisa uye yakakwirira-chaiyo micromachining application.
