Kupita patsogolo kwaposachedwa mu laser m'badwo wa laser ndi kafukufuku watsopano wa laser

Kupita patsogolo kwaposachedwa mu Nyanja ya Laser ndi ChatsopanoKafukufuku wa Laser
Posachedwa, katswiri wofufuza za Pulofesa Zhang Huaijin ndi Pulofesa Yu Haohai a Loandong University of Shandong University of Nanjong Yorks and Stunest Labount of Nanon-jonon yothandiza kupompa, ndipo adatenga Zachikhalidwe ND: Yvo4 laser laser ngati chinthu chofufuzira. Kutulutsa kwapamwamba kwambiri kwa superfluorescence kumapezeka podutsa malire a electron, komanso kulumikizana pakati pa bwalo la laser Kafukufukuyu adasindikizidwa mu chikhalidwe cha chilengedwe (Doi: 10,1038 / S41466333395959-9) pansi pa loser ". Yu Fu ndi Fei Liang, Wophunzira wa Phd wazaka 2020, yunivesite ya Shandong, ndi olemba achiwiri, ndi huang, ndi huang olemba.
Popeza Einstein anafunsa chiphunzitso chakumaso kwa kuwala kwa zaka zana zapitazi, njira yamalo a laser yayamba, ndipo mu 1960, a Maima adapanga yoyamba yokhazikika. Nthawi ya laser laser, kupumula kwamafuta ndi chinthu chofunikira kwambiri pa m'badwo wa lacernon, womwe umakhudzanso magwiridwe antchito a laser komanso mphamvu ya laser. Kupumula kwa mafuta ndi mphamvu kwa nthawi zonse kumaonedwa ngati magawo ofunika kwambiri omwe ali mu laser, omwe amayenera kuchepetsedwa ndi kusamutsidwa kosiyanasiyana kutentha ndi firiji. Chifukwa chake, mbiri ya kukula kwa laser imawerengedwa kuti ndi mbiri ya nkhondo yotentha.

Chiphunzitso cham'mbuyo cha Phonon-phonon Commegel Laser

Gulu lofufuzira lakhala likugwira ntchito yanthawi yayitali la laser komanso zinthu zaposachedwa kafukufuku, ndipo m'zaka zaposachedwa, njira yopuma imamveka bwino kuchokera ku malingaliro a State State. Kutengera ndi lingaliro loti kutentha (kutentha) kumangiriridwa mu ma phonosmic microsons, kumawerengedwa kuti kupumula kwa magetsi ndi njira ya magetsi, omwe angapeze njira zatsopano zamagetsi kuti apangidwelaser. Kutengera lingaliro ili, mfundo yatsopano ya ma elekitiron-phonon othandizira kuponya a Eleser, ndipo kulumikizana kwa ECton Nthawi yomweyo, njira yolumikizira ya Photon-phonon-phonon imapangidwa, yomwe imagwiritsa ntchito ukadaulo wa laseji wa Donwede. Laser ndi rare fullleth 1168nm ndi 1176nm adapangidwa. Pa maziko ake, kutengera mfundo yofunika kwambiri ya mbadwo wakunja wa laser, imapezeka kuti mankhwala a laser ndiokhazikika, omwe ali ofanana ndi lamulo la maginito mu njira yosinthira gawo.

Kuzindikira kwa Photon-phononKuponda laser

Ntchitoyi imapereka malingaliro atsopano pofufuza kafukufuku wa m'badwo wa laser,asitikali a laser, ndi laser yamphamvu, imalongosola gawo latsopano la laser]ma cinectic, mankhwala a laser, kuwonetsa laser ndi magawo ena okhudzana ndi ntchito.
