Iterambere rya vuba muburyo bwa laser generation hamwe nubushakashatsi bushya bwa laser

Iterambere rya vuba muburyo bwo kubyara laser kandi bushyaubushakashatsi bwa laser
Vuba aha, itsinda ry’ubushakashatsi bwa Porofeseri Zhang Huaijin na Porofeseri Yu Haohai wo muri Laboratwari ya Leta y’ibanze ya Crystal Materials yo muri kaminuza ya Shandong na Porofeseri Chen Yanfeng na Porofeseri He Cheng wo muri Laboratwari ya Leta ya Laboratwari ya Solid Microstructure Physics yo muri kaminuza ya Nanjing bakoranye kugira ngo bakemure icyo kibazo maze basaba ko hashyirwaho uburyo bwa lazeri bwa phoon-phonon bufatanya kuvoma. Imikorere ihanitse ya laser isohoka muri superfluorescence iboneka mugucamo urugero rwingufu za electron, kandi umubano wumubiri uri hagati yumubyigano wa laser nubushyuhe (numero ya fonone ufitanye isano rya hafi) urashyirwa ahagaragara, kandi imiterere yimvugo ni itegeko rya Curie. Ubushakashatsi bwasohotse mu itumanaho ry’ibidukikije (doi: 10.1038 / S41467-023-433959-9) ku izina rya “Photon-fonon ifatanije na laser”. Yu Fu na Fei Liang, umunyeshuri wa PhD wo mu cyiciro cya 2020, Laboratoire ya Leta y’ibikoresho bya Crystal, kaminuza ya Shandong, ni abanditsi ba mbere, Cheng He, Laboratoire ya Leta y’ibanze ya Solid Microstructure Physics, Kaminuza ya Nanjing, ni umwanditsi wa kabiri, naho abarimu ba Yu Haohai na Huaijin Zhang, kaminuza ya Shandong, na Yanfeng Chen, abanditsi ba kaminuza ya Nanjing.
Kuva Einstein yatangaga igitekerezo cyo gukwirakwiza imirasire yumucyo mu kinyejana gishize, uburyo bwa lazeri bwatejwe imbere, kandi mu 1960, Maiman yahimbye lazeri ya mbere ivomye neza. Mugihe cyibisekuru bya laser, kuruhuka kwubushyuhe nibintu byingenzi bifatika biherekeza ibisekuru bya laser, bigira ingaruka zikomeye kumikorere ya laser hamwe nimbaraga za laser. Kuruhuka kwubushyuhe ningaruka zubushyuhe burigihe byafashwe nkibintu byingenzi byangiza umubiri mubikorwa bya laser, bigomba kugabanywa nuburyo butandukanye bwo guhererekanya ubushyuhe hamwe nubuhanga bukonjesha. Kubwibyo, amateka yiterambere rya laser afatwa nkamateka yurugamba nubushyuhe bwimyanda.

Incamake yibyerekeranye na koperative ivoma laser

Itsinda ry’ubushakashatsi rimaze igihe kinini rikora ubushakashatsi bwa laser na nonlinear optique, kandi mumyaka yashize, uburyo bwo kuruhuka bwumuriro bwarasobanutse cyane duhereye kuri fiziki ikomeye ya leta. Hashingiwe ku gitekerezo cyibanze kivuga ko ubushyuhe (ubushyuhe) bugaragarira muri fonone ya microcosmic, hafatwa ko kuruhuka kwubushyuhe ubwabyo ari kwant inzira yo guhuza electron-fonon, ishobora gutahura kwaduka kwingero zingufu za elegitoronike ikoresheje igishushanyo mbonera gikwiye, kandi ikabona imiyoboro mishya yinzibacyuho kugirango itange uburebure bushya bwumurongo.laser. Hashingiwe kuri iki gitekerezo, hashyizweho ihame rishya rya koperative electron-fonon ivoma laser generation, kandi itegeko ryinzibacyuho ya electron muguhuza electron-fonon ikomoka mugufata Nd: YVO4, kirisiti yibanze ya lazeri, nkikintu gihagarariye. Muri icyo gihe, hubatswe koperative ya pompe ya foton-fonon idakonjeshejwe, ikoresha tekinoroji ya pompe ya laser diode. Laser ifite uburebure budasanzwe 1168nm na 1176nm yarateguwe. Hashingiwe kuri ibyo, hashingiwe ku ihame shingiro ry’ibisekuru bya laser hamwe no guhuza electron-fonon, usanga ko ibicuruzwa biva mu kirere hamwe n’ubushyuhe bihoraho, ibyo bikaba ari kimwe no kwerekana amategeko ya Curie muri magnetisme, kandi ikanagaragaza amategeko y’ibanze mu nzira y’inzibacyuho idahwitse.

Kumenyekanisha kugerageza koperative ya foton-fononkuvoma laser

Aka kazi gatanga icyerekezo gishya cyubushakashatsi bugezweho kubijyanye na laser generation,Ububiko bwa laser, hamwe ningufu nyinshi za laser, yerekana igipimo gishya cyubushakashatsi bwa tekinoroji yo kwagura laser hamwe nubushakashatsi bwa laser, kandi birashobora kuzana ibitekerezo bishya byubushakashatsi mugutezimberekwant optique, imiti ya laser, kwerekana laser hamwe nibindi bijyanye bijyanye.
