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 Microstructure Physics ya kaminuza ya Nanjing bakoranye kugira ngo bakemure igisubizo. ikibazo kandi cyasabye uburyo bwo kubyara lazeri ya phoon-fonon ikorana pompe, hanyuma ifata Nd: YVO4 laser kristal nkikintu gihagarariye ubushakashatsi. 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 ya Laboratwari ya Solid Microstructure Physics, kaminuza ya Nanjing, ni umwanditsi wa kabiri, na Profeseri Yu Haohai na Huaijin Zhang, kaminuza ya Shandong, na Yanfeng Chen, kaminuza ya Nanjing, ni abanditsi bahuje.
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) bugaragara muri fonone ya microcosmic, hafatwa ko kuruhuka kwubushyuhe ubwabyo ari inzira ya kwant yo guhuza electron-fonon, ishobora kumenya kwaduka kwaduka yingufu za elegitoronike ikoresheje igishushanyo mbonera gikwiye, kandi ikabona imiyoboro mishya ya electron kugirango itange umurongo mushyalaser. 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 ryo kubyara lazeri no guhuza electron-fonon, usanga ibicuruzwa biva mu mbuto ya laser hamwe nubushyuhe bihoraho, ibyo bikaba ari kimwe no kwerekana amategeko ya Curie muri magnetisme, kandi ikanagaragaza amategeko shingiro yumubiri mubikorwa byinzibacyuho 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.
