Malaser efiber mumunda wekutaurirana kwefiber ye optical
IyoLaser yeFaibhazvinoreva laser inoshandisa fibers dzegirazi dzisina kujeka pasi senzira yekuwana simba. Fiber lasers dzinogona kugadzirwa zvichibva pa fiber amplifiers, uye musimboti wadzo wekushanda ndewekuti: tora fiber laser inopombwa kwenguva refu semuenzaniso. Chikamu chefiber chakafukidzwa ne rare earth metal ions chinoiswa pakati pemagirazi maviri ane reflectivity yakasarudzwa. Mwenje wepombi unobatanidza ne fiber kubva mugirazi rekuruboshwe. Girazi rekuruboshwe rinotumira chiedza chepombi yese uye rinoratidza laser zvizere, kuitira kuti rishandise chiedza chepombi zvinobudirira uye kudzivirira chiedza chepombi kuti chisaite ruzha uye kukonzera chiedza chinobuda chisina kugadzikana. Endoscope yekurudyi inobvumira chikamu che laser kuti chipfuure nepakati kuitira kuti chigadzire mhinduro yemwaranzi we laser uye kuwana laser output. Maphoton ari pawavelength yepombi anotorwa ne medium, zvichiita ion number inversion, uye pakupedzisira anogadzira stimulated emission mu doped fiber medium kuenda ku output laser.
Hunhu hwemafiber lasers: Kushanda zvakanaka kwekubatanidza nekuti laser medium pachayo ndiyo nzira yekutungamira mafungu. Kushanda zvakanaka kwekushandura, muganhu wakaderera uye mhedzisiro yakanaka yekupisa; Ine huwandu hwakakura hwekubatana, kupararira kwakanaka uye kugadzikana. Mafiber lasers anogonawo kunzwisiswa senzira yekushandura mafungu inoshanda, kureva kuti, kushandura wavelength yechiedza chepombi kuita wavelength inononoka yemaion earth rare doped. Iyi wavelength inononoka ndiyo chaiyo wavelength yechiedza chinobuda chefiber laser. Haidzorwi newavelength yepombi uye inongoonekwa chete nezvinhu zve rare earth doping zviri muchinhu chacho. Naizvozvo, ma semiconductor lasers ema wavelengths mapfupi akasiyana uye simba rakawanda rinoenderana ne absorption spectra yemaion earth rare anogona kushandiswa semapombi sources kuti awane laser outputs yema wavelengths akasiyana.
Kupatsanurwa kwefiber laser: Kune mhando dzakasiyana dzefiber lasers. Zvichienderana ne gain medium, dzinogona kupatsanurwa se: rare earth doped fiber lasers, nonlinear effect fiber lasers, single crystal fiber lasers, uye plastic fiber lasers. Zvichienderana nechimiro chefiber, dzinogona kupatsanurwa se: single-clad fiber lasers uye double-clad fiber lasers. Zvichienderana nezvinhu zvakapatsanurwa, dzinogona kupatsanurwa mumhando dzinopfuura gumi dzakadai se erbium, neodymium, praseodymium, nezvimwewo. Zvichienderana nenzira yekupomba, inogona kupatsanurwa se: optical fiber end face pumping, micro prism side optical coupling pumping, ring pumping, nezvimwewo. Zvichienderana nechimiro che resonant cavity, dzinogona kupatsanurwa se: FP cavity fiber lasers, annular cavity fiber lasers, "8″ shaped cavity lasers, nezvimwewo. Zvichienderana ne working mode, dzinogona kupatsanurwa se: pulsed optical fiber uye continuous laser, nezvimwewo. Kuvandudzwa kwefiber lasers kuri kukurumidza. Pari zvino, zvakasiyana-siyanama laser ane simba guru, ma laser ekurova kwemoyo mapfupiuyemalaser anogadziriswa ane upamhi hwakatetepavari kubuda imwe mushure meimwe. Tevere, fiber lasers icharamba ichikura munzira dzine simba guru rekuburitsa, kunaka kwemwaranzi kuri nani, uye kukwirira kwepulse peaks.
