Fiber lasers mumunda we optical fiber kutaurirana

TheFiber Laserinoreva laser inoshandisa isingawanzo pasi-doped girazi fibers senzira yekuwana. Fiber lasers inogona kuvandudzwa yakavakirwa pafiber amplifiers, uye misimboti yavo yekushanda ndeiyi: tora kureba yakapomba fiber laser semuenzaniso. Chikamu chefiber doped ine isingawanzo pasi simbi ions inoiswa pakati pemagirazi maviri ane reflectivity yakasarudzwa. Chiedza chepombi chinobatanidza mufiibha kubva pagirazi rekuruboshwe. Girazi rekuruboshwe rinoendesa mwenje wese wepombi uye rinoratidza laser zvachose, kuitira kuti ishandise nemazvo mwenje wepombi uye kudzivirira mwenje wepombi kuti usadzoke uye uchikonzeresa kusagadzikana kubuda kwemwenje. Iyo yekurudyi endoscope inobvumira iyo laser chikamu kuti ipfuure kuitira kuti igadzire mhinduro yeiyo laser beam uye kuwana iyo laser kubuda. Mafotoni papombi wavelength anotorwa nepakati, achigadzira ion nhamba inversion, uye pakupedzisira anoburitsa inosimudzira kubuda mune doped fiber yepakati kusvika pakubuda laser.

Hunhu hwefiber lasers: Yakakwira coupling inoshanda nekuti iyo laser yepakati pachayo ndiyo waveguide yepakati. Kunyanya kutendeuka kushanda zvakanaka, kuderera kwechikumbaridzo uye kunaka kwekupisa kupisa; Iine hupamhi hwekubatanidza huwandu, kupararira kwakanaka uye kugadzikana. Fiber lasers inogona zvakare kunzwisiswa seanoshanda wavelength inoshandura, ndiko kuti, kushandura wavelength yechiedza chepombi kuita lasing wavelength yeiyo doped isingawanzo ion pasi. Iyi lasing wavelength ndiyo chaiyo inobuda mwenje wavelength yefiber laser. Iyo haina kudzorwa nepombi wavelength uye inotarirwa chete neasingawanzo pasi doping zvinhu muzvinhu. Naizvozvo, semiconductor lasers eakasiyana mapfupi marefu marefu uye simba rakakwirira rinoenderana neabsorption spectra yeasingawanzo pasi ion anogona kushandiswa sepombi masosi kuwana laser kubuda kweakasiyana wavelengths.

Fiber laser classification: Kune akawanda marudzi efiber lasers. Zvinoenderana nepakati pekuwana, vanogona kuverengerwa se: isingawanzo pasi doped fiber lasers, nonlinear effect fiber lasers, single crystal fiber lasers, uye epurasitiki fiber lasers. Zvinoenderana nefiber chimiro, vanogona kuiswa mu: single-clad fiber lasers uye kaviri-clad fiber lasers. Maererano nedoped elements, zvinogona kuiswa mumhando dzinopfuura gumi dzakadai se erbium, neodymium, praseodymium, etc. Maererano nenzira yekupomba, inogona kugoverwa se: optical fiber end face pumping, micro prism side optical coupling kupomba, ring pumping, etc. Maererano nekugadzirwa kwefiber cavity resonant, FP resonant fibre cavity, FP resonant fibre cavity: lasers, "8" yakaumbwa mhango lasers, etc. Zvinoenderana nekushanda modhi, anogona kuverengerwa se: pulsed optical fiber uye inoenderera mberi laser, nezvimwewo. Kugadzirwa kwefiber lasers kuri kukurumidza.high-simba lasers, ultrashort pulse lasers,uyenhete-linewidth tunable lasersvari kubuda mumwe pashure pomumwe. Tevere, mafiber lasers acharamba achikura munzira dzekubuda kwesimba repamusoro, mhando yedanda iri nani, uye yakakwirira pulse peaks.
