1, tsarin famfo hasken sarari

Farkon fiber Laser mafi yawa amfani da Tantancewar famfo fitarwa,Laserfitarwa, ƙarfin fitar da shi yana da ƙasa, don haɓaka ƙarfin fitarwa na fiber Laser cikin ɗan gajeren lokaci akwai wahala mafi girma. A 1999, da fitarwa ikon fiber Laser bincike da ci gaban filin karya 10,000 watts a karon farko, da tsarin na fiber Laser ne yafi amfani da Tantancewar bidirectional famfo, forming wani resonator, tare da bincike na gangara yadda ya dace na fiber. Laser ya kai 58.3%.
Duk da haka, ko da yake amfani da fiber famfo haske da Laser hada biyu fasaha don bunkasa fiber Laser iya yadda ya kamata inganta fitarwa ikon fiber Laser, amma a lokaci guda akwai rikitarwa, wanda ba shi da kyau ga na gani ruwan tabarau gina Tantancewar hanya. da zarar Laser bukatar da za a motsa a cikin aiwatar da gina Tantancewar hanya, sa'an nan da Tantancewar hanya kuma bukatar a sake gyara, wanda iyakance fadi da aikace-aikace na Tantancewar famfo tsarin fiber Laser.

2, tsarin oscillator kai tsaye da tsarin MOPA

Tare da ci gaban fiber Laser, cladding ikon strippers sun sannu a hankali maye gurbin ruwan tabarau kayayyakin, sauƙaƙa ci gaban matakai na fiber Laser da kuma kai tsaye inganta tabbatarwa ingancin fiber Laser. Wannan yanayin ci gaba yana nuna alamar amfani a hankali na laser fiber. Tsarin oscillator kai tsaye da tsarin MOPA sune mafi yawan tsarin yau da kullun na Laser fiber akan kasuwa. Tsarin oscillator kai tsaye shine cewa grating yana zaɓar tsayin tsayin daka a cikin aiwatar da oscillation, sannan ya fitar da tsayin da aka zaɓa, yayin da MOPA ke amfani da tsayin tsayin da aka zaɓa ta grating azaman hasken iri, kuma hasken iri yana ƙaruwa ƙarƙashin aikin na farko. -level amplifier, don haka ikon fitarwa na fiber Laser kuma za a inganta zuwa wani iyaka. Na dogon lokaci, ana amfani da Laser fiber tare da tsarin MPOA azaman tsarin da aka fi so don laser fiber mai ƙarfi. Duk da haka, binciken da ya biyo baya ya gano cewa babban ƙarfin wutar lantarki a cikin wannan tsari yana da sauƙi don haifar da rashin daidaituwa na rarraba sararin samaniya a cikin fiber Laser, kuma za a yi tasiri ga hasken laser na fitarwa zuwa wani matsayi, wanda kuma yana da tasiri kai tsaye. akan tasirin fitarwa mai ƙarfi.

Tare da haɓaka fasahar yin famfo

Tsayin famfo na farkon ytterbium-doped fiber Laser yawanci shine 915nm ko 975nm, amma waɗannan tsayin igiyoyin famfo guda biyu sune kololuwar ɗaukar ytterbium ions, don haka ana kiranta famfo kai tsaye, yin famfo kai tsaye ba a yi amfani da shi sosai ba saboda asarar adadi. In-band fasaha fasaha ce mai tsawo na fasahar yin famfo kai tsaye, wanda tsawon zangon da ke tsakanin tsawon famfo da na'ura mai watsawa ya yi kama da haka, kuma yawan asarar da ake yi na yin famfo a cikin band ɗin ya yi ƙasa da na yin famfo kai tsaye.

High ikon fiber Lasermatsalar ci gaban fasaha

Ko da yake fiber Laser da high aikace-aikace darajar a soja, likita da sauran masana'antu, kasar Sin ta inganta da fadi da aikace-aikace na fiber Laser ta hanyar kusan shekaru 30 na fasaha bincike da kuma ci gaba, amma idan kana so ka yi fiber Laser iya fitar da mafi girma iko, har yanzu akwai sauran. matsaloli da yawa a cikin fasahar data kasance. Misali, ko ikon fitarwa na Laser fiber na iya kaiwa yanayin yanayin fiber guda ɗaya 36.6KW; Tasirin ikon yin famfo akan fiber Laser fitarwa ikon; Tasirin tasirin ruwan tabarau na thermal akan ikon fitarwa na Laser fiber.

Bugu da kari, bincike na mafi girma ikon fitarwa fasahar na fiber Laser ya kamata kuma la'akari da kwanciyar hankali na transverse yanayin da photon darkening sakamako. Ta hanyar bincike, a bayyane yake cewa tasirin tasirin yanayin rashin kwanciyar hankali shine dumama fiber, kuma tasirin duhu na photon galibi yana nufin cewa lokacin da fiber Laser ya ci gaba da fitar da daruruwan watts ko kilowatts na iko da yawa, ikon fitarwa zai nuna saurin raguwar yanayin, kuma akwai ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙarfi akan ci gaba da fitar da wutar lantarki mai ƙarfi na Laser fiber.

Ko da yake ba a fayyace takamaiman abubuwan da ke haifar da tasirin duhun photon ba a halin yanzu, yawancin mutane sun yi imanin cewa cibiyar tabarbarewar iskar oxygen da ɗaukar nauyin canja wurin na iya haifar da faruwar tasirin duhun photon. A kan waɗannan abubuwa biyu, ana ba da shawarar hanyoyi masu zuwa don hana tasirin duhun photon. Kamar su aluminum, phosphorus, da dai sauransu, don kauce wa cajin canja wurin sha, sa'an nan kuma inganta aikin fiber da aka gwada da kuma amfani, takamaiman misali shi ne kula da 3KW ikon na da yawa hours da kuma kula da 1KW ikon barga fitarwa na 100 hours.
