Kuti tinzwisise zvakadzama zvinodiwa nemanyuko epombi emafiber lasers nema solid-state lasers, zvakakosha kuti tinyatsoongorora mashandiro anoita ma lasers aya uye basa remapump sources mukushanda kwawo. Pano, tichawedzera ruzivo rwekutanga kuti tifunge nezvezvinhu zvakaoma zvemapombi, mhando dzemapump sources anoshandiswa, uye kukanganisa kwazvinoita pamashandiro elaser. Kusarudzwa uye kurongeka kwemapump sources kunokanganisa zvakananga kushanda kwelaser, simba rekubuda, uye mhando yemwaranzi. Kubatana kwakanaka, kufananidza wavelength, uye kutonga kwekupisa kwakakosha pakuvandudza mashandiro uye kuwedzera hupenyu hwelaser. Kufambira mberi mu tekinoroji yelaser diode kuri kuramba kuchivandudza mashandiro uye kuvimbika kwemafiber lasers ese ari maviri nesolid-state, zvichiita kuti ave anoshanda zvakasiyana-siyana uye asingadhuri kune akasiyana mashandisirwo.
- Zvinodiwa paManyuko ePombi yeFiber Lasers
MaDiodhi eLaserseManyuko ePombi:Mafiber laser anonyanya kushandisa ma laser diode senzvimbo yepombi yavo nekuda kwekushanda kwavo zvakanaka, saizi yavo iri pakati, uye kugona kwavo kugadzira wavelength yechiedza inoenderana ne absorption spectrum ye doped fiber. Sarudzo ye laser diode wavelength yakakosha; semuenzaniso, dopant inowanikwa muma fiber lasers iYtterbium (Yb), ine optimal absorption peak inosvika 976 nm. Saka, ma laser diode anoburitsa pa wavelength iyi kana pedyo neiyi anonyanya kufarirwa pakupomba ma Yb-doped fiber lasers.
Dhizaini yeFiber Yakaputirwa Kaviri:Kuti vawedzere kushanda zvakanaka kwekupinza chiedza kubva mumapombi elaser diodes, mafiber laser anowanzo shandisa dhizaini yefiber ine jira rakapfeka kaviri. Pakati pepakati pane active laser medium (semuenzaniso, Yb), nepo cladding layer yekunze yakakura ichitungamira mwenje wepombi. Pakati pepakati panobata mwenje wepombi uye panogadzira laser action, nepo cladding ichibvumira huwandu hwakawanda hwemwenje wepombi kuti ushande nepakati, zvichiwedzera kushanda zvakanaka.
Kufananidza kweWavelength uye Kushanda Pakubatanidza: Kupomba zvinobudirira hakudi kungosarudza ma diode elaser ane urefu hwakakodzera hwewavelength chete asiwo kugadzirisa kushanda zvakanaka kwekubatanidza pakati pe ma diode nefaibha. Izvi zvinosanganisira kurongeka kwakanyatsogadzirwa uye kushandiswa kwezvinhu zvakaita sema lenses nema couplers kuona kuti chiedza chepombi chakanyanya kupinzwa mu fiber core kana cladding.
-MaLaser Emamiriro AkasimbaZvinodiwa Pakunobva Pombi
Kupomba Kwemaziso:Kunze kwema laser diodes, ma solid-state lasers (kusanganisira ma bulk lasers akadai seNd:YAG) anogona kupombwa nechiedza nemwenje inopenya kana mwenje ye arc. Marambi aya anoburitsa chiedza chakasiyana-siyana, icho chikamu chacho chinoenderana nemabhendi ekunyudza e laser medium. Kunyange zvazvo isingashande zvakanaka se laser diode pumping, nzira iyi inogona kupa simba re pulse rakawanda, zvichiita kuti ive yakakodzera kushandiswa kunoda simba repamusoro.
Kugadziriswa kwePombi:Kugadziriswa kwepombi inobva muma lasers akasimba kunogona kukanganisa mashandiro ayo zvakanyanya. Kupomba kwekupedzisira uye kupomba kwepadivi zvinhu zvakajairika. Kupomba kwekupedzisira, uko chiedza chepombi chinotungamirirwa pamwe chete ne optical axis ye laser medium, kunoita kuti pave nekupindirana kuri nani pakati pechiedza chepombi ne laser mode, zvichiita kuti pave nekushanda kwakasimba. Kupomba kwepadivi, kunyange zvazvo kungasashanda zvakanaka, kuri nyore uye kunogona kupa simba rakawanda rema rods kana slabs ane dhayamita yakakura.
Kutarisira Kupisa:Malaser efiber nesolid-state anoda kutarisirwa kwekupisa kwakanaka kuti agadzirise kupisa kunobva papombi. Mumalaser efiber, nzvimbo yakareba yefiber inobatsira mukupisa. Mumalaser e-solid-state, masisitimu ekutonhodza (akadai sekutonhodza mvura) anodiwa kuti arambe achishanda zvakanaka uye kudzivirira kupisa kana kukuvara kwelaser medium.
