fiber laser inoshanda sei? -Lisa anobva kuRuijie fiber laser yekucheka fekitori
Iyo fiber inoshandiswa senge yepakati svikiro relaser yako ichave yakadonhedzwa mune isingawanzo-yepasi zvinhu, uye iwe kazhinji unozoona kuti iyi iErbium.Chikonzero nei izvi zvichiitwa imhaka yekuti mazinga eatomu yezvinhu izvi zvepasi ane akanyanya kushanda simba mazinga, ayo anobvumira yakachipa diode laser pombi sosi kuti ishandiswe, asi izvo zvicharamba zvichipa yakakwira kubuda kwesimba.
Semuenzaniso, nedoping fiber muErbium, chiyero chesimba chinogona kutora mafotoni ane wavelength ye980nm inoora kuita meta-yakagadzikana yakaenzana ne1550nm.Zvinoreva izvi ndezvekuti iwe unogona kushandisa laser pombi sosi pa980nm, asi uchiri kuwana yemhando yepamusoro, yakakwira simba uye yakakwira simba laser beam ye1550nm.
Maatomu eErbium anoita senge laser medium mune doped fiber, uye mafotoni anoburitswa anoramba ari mukati meiyo fiber core.Kugadzira mhango umo mafotoni anoramba akabatwa, chimwe chinhu chinozivikanwa seFiber Bragg Grating chinowedzerwa.
A Bragg Grating ingori chikamu chegirazi chine mitsetse mukati - uko ndiko kwakashandurwa index refractive.Chero nguva iyo mwenje ichipfuura muganhu pakati peimwe refractive index uye inotevera, diki diki rechiedza rinodzoserwa kumashure.Chaizvoizvo, iyo Bragg Grating inoita kuti fiber laser iite segirazi.
Iyo pombi yelaser inotariswa mukuvhara iyo inogara yakatenderedza fiber musimboti, sezvo iyo fiber core pachayo idiki kwazvo kuti ive yakaderera-mhando diode laser yakatarisana mairi.Nekupomba iyo laser muvharo yakatenderedza musimboti, iyo laser inorovererwa mukati, uye pese painopfuura musimboti, yakawanda uye yakawanda yepombi mwenje inotorwa nepakati.
