Laser sosi tekinoroji yeye Optical fiber inonzwa chikamu chechipiri

2.2 Single Wavelength kutsvairaLaser Source

Kunyatsoziva kweLaser single wave wavelaserCavity (kazhinji iyo Center Wavelength yeBandwidth Bandwidth), kuitira kuti uwane iyo yekudzora uye kusarudzwa kweiyo Oscillating Mode muCavity, kuitira kuti uwane chinangwa chekutora mavambo ekunze. Zvichienderana neiyi nheyo, kutanga kwa1980, kuzadzikiswa kwechidimbu fiber laser Muna 2011, zhu et al. Inoshandiswa mahara mafirita kuti uwane imwe chete-wavelength tunable laver inobuda neyakatetepa mutsara. Muna 2016, Raylights Letswidth Commenism Spection yakaiswa kune Dual-Wavel Compression, kureva kuti, kushungurudzika kwakaitwa Dual-wavelength yakagadzikana kubuda nemutsara wehupamhi hwenguva dzinenge 700 hz. Muna 2017, zhu et al. Yakashandiswa Griphene uye Micro-Nano Fiber Bragg Grater kuti iite Wese-Firithiin Laser Leverwitth Servers Sezvinoratidzwa muhuwandu 5

2.3 White Laser Chiedza Tsime

Iko kuvandudzwa kwesosi chena kwechiedza kwakawana matanho akasiyana siyana akadai saHalogen tungsten Lamm, Deerium Lamp,semiconductor laseruye Supercontinuum mwenje sosi. Kunyanya, iyo Supercontinuum Light Source, pasi pekunakidzwa kweiyo femtosecond kana pombi yemirairo yakasiyana-siyana muzvinyorwa zvevasimba Mukuwedzera, nekugadzirisa iyo kupararira uye isiri yeiyo inokosha fiber, iyo spectrum yayo inogona kutowedzerwa kune iyo yepakati-infrared bhendi. Rudzi urwu rwe laser sosi rwakashandiswa kwazvo muminda yakawanda, yakadai seyekunyaniswa kakawanda tomography, gasi kuwanikwa, biology kufungidzira uye zvichingofungidzira uye zvichingodaro. Nekuda kwekukanganiswa kwechiedza sosi uye nonlinear svutugadzike, iyo yekutanga superinuum spectrum yakanyanya kugadzirwa neiyo yakasimba-nyika laser pumping girazi rekugadzira supercontinuum spectrum spectrum in. Kubva ipapo, optical fiber zvishoma nezvishoma ive yepakati yepamusoro yekugadzira huwandu hwehuremu hwekuita supercontinuum nekuda kweiyo hombe isingamapuritiri uye diki transcation mode. Iyo main nonlinear mhedzisiro inosanganisira mana-mafungu-kusanganisa, kusanganisa kwekuzvimiririra, ruzha rwekuparadzira, solitonion-famba Kazhinji, iye zvino supercontinuum mwenje sosi inonyanya kuenderana nekuvandudza iyo laser simba uye kuwedzera huwandu hwekupindira, uye teerera kune hwayo kudzora.

Iri pepa rinopfupisa uye rinoongorora laser masosi anoshandiswa kutsigira fiber sensing tekinoroji, kusanganisira mutsara wakamanikana laser Izvo zvinodiwa zvekushandisa uye chinzvimbo chekuvandudza chevanodonha mumunda weFiber kunzwa kwakaunzwa zvakadzama. Nekuongorora zvavanoda uye zvinopiswa mamiriro, zvinogumiswa kuti iyo yakakodzera laser sosi yekunzwa fiber inogona kuwana Ultra-yakatetepa uye Ultra-yakagadzikana laser kune chero bhendi uye chero nguva. Naizvozvo, isu tinotanga nemutsara wakamanikana Laser, tunable yakatetepa mutsara waibhururuka uye chena lever gofu bandwidth bandwidth
