Fiber laser yekucheka uye Medical
Fiber laser yekucheka uye mushonga, fiber laser yekucheka muchina inoiswa doped fiber pachayo sechinhu chinoshanda, uye iyo fiber laser yekucheka muchina pachayo, asi zvakare tamba basa rekutungamira wave solid-state laser.Resonator, ine chinhu chinoshanda, pombi sosi zvikamu zvitatu zvakakosha.Mumakore achangopfuura, faibha lasers mumaindasitiri minda mukuwedzera kune akasiyana siyana mashandisirwo, uye kuwedzera kukurumbira mundima yekurapa.
Fiber Technology Center, University of Sydney, Australia (OFT C) yeStuart Jackson yakati: "fiber laser yekucheka muchina wekushandiswa kwekuvhiya, zvakakosha kubatanidza lasers, kushomeka kwekugadzirisa, kushanda kwakanyanya kwepamusoro uye kunaka kwekupisa kwefiber laser.kuvaita kuti vanyatsokodzera kuvhiyiwa maapplication nekuti vari kushandisa diode-pumped, saka iri compact kwazvo.Fiber chimiro kupfuura solid-state laser material yakakwira nekuti yakarerutsa kudiwa kwekuwedzera kufambisa fiber, nekudaro ichidzikisa mutengo uye nekuderedza iyo system's Complexity.
Fiber laser yekucheka muchina muna 1963 naElias Spritzer kugadzirwa.Usati wapedzisira wapinda mukushandiswa kwekutengeserana, mushure meanenge makore maviri enguva yekusimudzira.Pakutanga, kushandiswa kwe-single-mode diode laser pumped, chete nemwaranzi makumi emamililita.Asi ine vashandisi vazhinji vachiri kukwezva nekuda kwekuwana kwavo kwakakwira, inogona kuita yakawanda-modhi inoenderera mberi kushanda kweasingawanzo pasi ion, iri crystal laser haigone kuwanikwa.1990, fiber lasers kuti iwane kusvetuka-watt yekubuda nhanho, saka, yakashuma erbium-doped fiber laser inobuda simba kumusoro 4 W, iyi budiriro nhasi tinoona simba re10 W uye yakakwirira single-modhi fiber lasers hwaro.
Mune fiber laser yekucheka muchina, iyo fiber pachayo inoita senge resonant mhango.Midziyo iyi inowanzo sanganisira erbium doped single-mode core ytterbium (kana misanganiswa yacho), kana chinhu chisingawanikwe pasi.Simba rinobva kune rakasimba mwenje sosi, rinosanganiswa nekuvharwa kwefayibha, uyezve mukati mepakati, pombi inoita maatomu.Mundima yezvekurapa, iyo wavelength inonyanya kudiwa ndeiyi: 1.3μm bhendi rekufungidzira, 1.5μm (peak yekunyudza mvura) -4μm bhendi rekuvhiya, rinobva musimba remamililita kusvika kune anopfuura 100 W.
Jackson akati: "Kushandiswa kweCW lasers, biomedical application, kunyanya chero yakakwira-simba CW lasers, inogona kubatsirwa kubva kune fiber laser yekucheka muchina nemuchina wefiber laser wekucheka unopa kunyatsoshanda, kureba tuning siyana, uye zvese zvinobuda.simba remhando ine mukana weiyo nani danda mhando, kunyanya yakakurumbira;kuitira kuti fiber lasers ienderane mune zvekurapa zvikumbiro zvinoramba zvichiwedzera.“
