Tsarin hanyar gani na murabba'i mai kusurwa huɗuna'urorin laser masu bugun jini
Bayani game da ƙirar hanyar gani
Na'urar laser mai amfani da hasken rana mai motsi biyu mai kama da na soliton resonant thulium-doped fiber laser wadda aka yi bisa tsarin madubin zare mara layi.
2. Bayanin hanyar gani
Na'urar soliton mai juyi mai juyi mai juyi mai juyi mai juyi mai juyi mai juyi biyuLaser ɗin fiberya ɗauki tsarin rami mai siffar "8″" (Hoto na 1).
Bangaren hagu shine babban madauri mai layi ɗaya, yayin da ɓangaren dama shine madubin madubi mai layi ɗaya mara layi ɗaya. Madauri mai layi ɗaya na hagu ya haɗa da mai rabawa, zare mai layi ɗaya mai tsawon thulium 2.7m (SM-TDF-10P130-HE), da kuma mai haɗin fiber mai layi ɗaya mai tsawon μm 2 tare da haɗin haɗin 90:10. Mai rabawa ɗaya mai dogaro da polarization (PDI), Mai kula da polarization guda biyu (Masu kula da polarization: PC), Zare mai kulawa da polarization 0.41m (PMF). Tsarin madubin zoben fiber mai layi ɗaya mara layi ɗaya yana samuwa ta hanyar haɗa haske daga madauri ɗaya na hagu zuwa madubin zoben fiber mai layi ɗaya a dama ta hanyar haɗin optical na tsarin 2×2 tare da ma'auni na 90:10. Tsarin madubin zoben fiber mai layi ɗaya mara layi ɗaya a dama ya haɗa da zaren optical na tsawon mita 75 (SMF-28e) da mai kula da polarization. Ana amfani da zaren optical na tsawon mita ɗaya mai tsawon mita 75 don haɓaka tasirin mara layi ɗaya. A nan, ana amfani da na'urar haɗa zare mai amfani da haske mai girman 90:10 don ƙara bambancin matakin da ba na layi ba tsakanin yaɗuwar agogo da akasin agogo. Jimlar tsawon wannan tsarin zango mai tsawon zango biyu shine mita 89.5. A cikin wannan saitin gwaji, hasken famfo da farko yana ratsawa ta cikin na'urar haɗa katako don isa ga zaren gani mai matsakaicin gani na thulium. Bayan zaren gani mai girman thulium, an haɗa na'urar haɗa 90:10 don zagayawa kashi 90% na kuzarin da ke cikin ramin kuma ya aika kashi 10% na kuzarin daga ramin. A lokaci guda, matattarar Lyot mai birefringent ta ƙunshi zaren gani mai kula da polarization wanda ke tsakanin masu sarrafa polarization guda biyu da polarizer, wanda ke taka rawa wajen tace tsawon spectral.

A halin yanzu, akwai hanyoyi guda biyu na asali don ƙara ƙarfin bugun jini na lasers masu bugun jini. Hanya ɗaya ita ce rage tasirin da ba na layi ba kai tsaye, gami da rage ƙarfin bugun jini ta hanyoyi daban-daban, kamar amfani da sarrafa watsawa don bugun jini mai shimfiɗa, manyan oscillators masu girgiza, da lasers masu raba haske, da sauransu. Wata hanyar kuma ita ce neman sabbin hanyoyin da za su iya jure ƙarin tarin matakan da ba na layi ba, kamar kamanni da bugun jini mai kusurwa huɗu. Hanyar da aka ambata a sama za ta iya haɓaka ƙarfin bugun jini na cikin nasara.laser mai bugun jinizuwa ga dubban nanojoules. Rarraba soliton resonance (Rarraba soliton resonance: DSR) wata hanya ce ta samar da motsin motsi mai kusurwa huɗu da N. Akhmediev da abokan aikinsa suka fara gabatar a shekarar 2008. Halayyar bugun motsin motsi na soliton resonance shine, yayin da yake kiyaye daidaiton amplitude, faɗin bugun da kuzarin bugun motsi mai kusurwa huɗu mara rabewa yana ƙaruwa cikin sauƙi tare da ƙaruwar ƙarfin famfo. Wannan, zuwa wani mataki, yana karya iyakancewar ka'idar soliton ta gargajiya akan kuzarin bugun jini ɗaya. Rarraba soliton resonance ana iya cimma shi ta hanyar gina cikakkar sha da kuma juyawar shaƙa mai cikawa, kamar tasirin juyawar polarization mara layi (NPR) da tasirin madubin zare mara layi (NOLM). Yawancin rahotanni kan samar da bugun motsin motsi na soliton resonance na rabewa sun dogara ne akan waɗannan hanyoyin kulle yanayi guda biyu.
