Ma fiber lasers amachulukitsa kuchuluka kwa ma laser a mafakitale chaka ndi chaka chifukwa cha kapangidwe kake kosavuta, mtengo wotsika, kutembenuka kwamagetsi kwamagetsi, komanso zotsatira zabwino. Malinga ndi ziwerengero, ma fiber lasers adapanga 52.7% ya msika wa laser mafakitale mu 2020.
Kutengera mawonekedwe a mtengo wotulutsa, fiber lasers imatha kugawidwa m'magulu awiri:laser mosalekezandilaser pulse. Kodi pali kusiyana kotani paukadaulo pakati pa ziwirizi, ndipo ndi mawonekedwe otani omwe ali oyenera? Zotsatirazi ndi kuyerekezera kosavuta kwa ntchito muzochitika zambiri.
Monga momwe dzinalo likusonyezera, kutulutsa kwa laser ndi laser fiber kosalekeza kumapitilira, ndipo mphamvuyo imasungidwa pamlingo wokhazikika. Mphamvu iyi ndi mphamvu yovotera ya laser.Ubwino wa ma lasers osalekeza ndikugwira ntchito kwanthawi yayitali.
Laser ya pulse laser ndi "intermittent". Zachidziwikire, nthawi yapakatikati iyi nthawi zambiri imakhala yayifupi kwambiri, nthawi zambiri imayesedwa mu ma milliseconds, ma microseconds, kapena ngakhale nanoseconds ndi picoseconds. Poyerekeza ndi laser yosalekeza, mphamvu ya laser pulse imasintha nthawi zonse, kotero pali malingaliro a "crest" ndi "through".
Kupyolera mu kusinthasintha kwa pulse, laser pulsed imatha kumasulidwa mwamsanga ndikufika mphamvu yaikulu pamalo apamwamba, koma chifukwa cha kukhalapo kwa ufa, mphamvu zambiri zimakhala zochepa.Ndi zotheka kuti ngati mphamvu pafupifupi ali yemweyo, nsonga ya mphamvu ya kugunda laser akhoza kukhala wamkulu kuposa wa laser mosalekeza, kukwaniritsa mphamvu kachulukidwe kwambiri kuposa laser mosalekeza, amene akuwonetseredwa mu lalikulu malowedwe luso lolowera mu processing zitsulo. Panthawi imodzimodziyo, imakhalanso Yoyenera kwa zipangizo zowononga kutentha zomwe sizingathe kupirira kutentha kwakukulu, komanso zipangizo zina zowonetsera kwambiri.
Kupyolera mu mphamvu linanena bungwe makhalidwe awiri, tikhoza kusanthula ntchito kusiyana.
CW fiber lasers nthawi zambiri ndi yoyenera:
1. Kukonza zida zazikulu, monga makina agalimoto ndi sitima, kudula ndi kukonza mbale zazikulu zachitsulo, ndi zochitika zina zopangira zomwe sizimakhudzidwa ndi kutentha koma zimakhudzidwa kwambiri ndi mtengo.
2. Amagwiritsidwa ntchito podula opaleshoni ndi coagulation m'chipatala, monga hemostasis pambuyo pa opaleshoni, ndi zina zotero.
3. Amagwiritsidwa ntchito kwambiri pamakina olankhulirana opangidwa ndi fiber optical potumiza ma siginecha ndi kukulitsa, mokhazikika komanso phokoso lotsika.
4. Amagwiritsidwa ntchito ngati kusanthula kowoneka bwino, kuyesa kwa atomic physics ndi lidar pankhani ya kafukufuku wasayansi, kupereka mphamvu yayikulu komanso kutulutsa kwa laser kwapamwamba kwambiri.
Ma pulsed fiber lasers nthawi zambiri amakhala oyenera:
1. Kukonza mwatsatanetsatane zinthu zomwe sizingathe kupirira kutenthedwa kwamphamvu kapena zinthu zosasunthika, monga kukonza tchipisi tamagetsi, magalasi a ceramic, ndi zida zamankhwala.
2. Zinthuzo zimakhala ndi chiwonetsero chachikulu ndipo zimatha kuwononga mosavuta mutu wa laser wokha chifukwa cha kusinkhasinkha. Mwachitsanzo, kukonza zinthu zamkuwa ndi aluminiyamu
3. Kusamalira pamwamba kapena kuyeretsa kunja kwa magawo owonongeka mosavuta
4. Kukonza zinthu zomwe zimafuna mphamvu zazifupi zazifupi komanso kulowa mwakuya, monga kudula mbale, kubowola zitsulo, etc.
5. Mikhalidwe yomwe ma pulse amafunika kugwiritsidwa ntchito ngati mawonekedwe azizindikiro. Monga optical CHIKWANGWANI kulankhulana ndi kuwala CHIKWANGWANI masensa, etc.
6. Amagwiritsidwa ntchito m'munda wa biomedical pakuchita opaleshoni yamaso, kuchiza khungu ndi kudula minofu, ndi zina zotero, ndi khalidwe lapamwamba lamtengo wapatali komanso kusinthasintha
7. Pakusindikiza kwa 3D, zigawo zachitsulo zopanga zolondola kwambiri komanso zovuta zimatha kukwaniritsidwa
8. Zida zamakono za laser, etc.
Pali kusiyana pakati pa pulsed CHIKWANGWANI lasers ndi mosalekeza CHIKWANGWANI lasers malingana ndi mfundo, makhalidwe luso ndi ntchito, ndipo aliyense ndi oyenera nthawi zosiyanasiyana. Ma lasers a pulsed fiber ndi oyenera kugwiritsa ntchito zomwe zimafuna mphamvu yayikulu kwambiri komanso kusinthasintha kwa magwiridwe antchito, monga kukonza zinthu ndi biomedicine, pomwe ma laser opitilira muyeso ndi oyenera kugwiritsa ntchito zomwe zimafunikira kukhazikika kwapamwamba komanso mtengo wapamwamba, monga kulumikizana ndi kafukufuku wasayansi. Kusankha mtundu woyenera wa fiber laser kutengera zosowa zapadera kumathandizira kuwongolera magwiridwe antchito komanso kugwiritsa ntchito bwino.
