Iterambere riherutse mu buryo bwo gukora laser n'ubushakashatsi bushya bwa laser

Iterambere riherutse mu buryo bwo gukora laser n'ibishyaubushakashatsi kuri laser
Vuba aha, itsinda ry’ubushakashatsi rya Porofeseri Zhang Huaijin na Porofeseri Yu Haohai bo muri Laboratwari y’ingenzi ya Leta y’ibikoresho bya Crystal yo muri Kaminuza ya Shandong na Porofeseri Chen Yanfeng na Porofeseri He Cheng bo muri Laboratwari y’ingenzi ya State y’imiterere y’ubutabire ya Microstructure ya Kaminuza ya Nanjing bakoranye kugira ngo bakemure ikibazo banatanga igitekerezo cy’uburyo bwo gukora laser bwo gukora phoon-phonon hamwe na crystal ya laser ya Nd: YVO4 nk’ikintu cy’ingenzi mu bushakashatsi. Umusaruro wa laser uhagije wa superfluorescence uboneka binyuze mu kurenga umupaka w’ingufu za electron, kandi isano iri hagati y’umupaka wo gukora laser n’ubushyuhe (umubare wa phonon ufitanye isano ya hafi) iragaragazwa, kandi imiterere y’imvugo ni imwe n’itegeko rya Curie. Ubushakashatsi bwasohotse mu kinyamakuru Nature Communications (doi:10.1038/ S41467-023-433959-9) ku izina rya “Photon-phonon hamwe na crystal ya laser”. Yu Fu na Fei Liang, umunyeshuri wa PhD mu mwaka wa 2020, Laboratwari y’ingenzi ya Leta y’ibikoresho bya Crystal, Kaminuza ya Shandong, ni abanditsi ba mbere, Cheng He, Laboratwari y’ingenzi ya Leta y’ubumenyi bw’imiterere y’ibintu bifatika, Kaminuza ya Nanjing, ni umwanditsi wa kabiri, naho Porofeseri Yu Haohai na Huaijin Zhang bo muri Kaminuza ya Shandong, na Yanfeng Chen, wo muri Kaminuza ya Nanjing, ni abanditsi bahuje.
Kuva Einstein yatanga igitekerezo cy’imirasire y’urumuri mu kinyejana gishize, uburyo bwa laser bwakozwe neza, kandi mu 1960, Maiman yavumbuye laser ya mbere ikoreshwa mu buryo bw’ikoranabuhanga. Mu gihe cyo gukora laser, kuruhuka kw’ubushyuhe ni ikintu cy’ingenzi gikoreshwa mu buryo bw’umubiri giherekeza gukora laser, bigira ingaruka zikomeye ku mikorere ya laser n’imbaraga za laser ziboneka. Kuruhuka kw’ubushyuhe n’ingaruka z’ubushyuhe byagiye bifatwa nk’ibintu by’ingenzi byangiza imiterere ya laser, bigomba kugabanywa n’ikoranabuhanga ritandukanye ryo kohereza ubushyuhe no gukonjesha. Kubwibyo, amateka y’iterambere rya laser afatwa nk’amateka yo guhangana n’ubushyuhe bwangiritse.

Incamake y'inyigisho za laser ya photon-phonon cooperative pumping

Itsinda ry’ubushakashatsi rimaze igihe kinini rikora ubushakashatsi ku bikoresho bya lazeri n’ibitari umurongo, kandi mu myaka ya vuba aha, inzira yo kuruhuka ubushyuhe yasobanuwe cyane ukurikije imiterere ya fiziki ya solid state. Hashingiwe ku gitekerezo cy’ibanze cy’uko ubushyuhe (ubushyuhe) bugaragara muri phononi ntoya z’isi, bifatwa ko kuruhuka ubushyuhe ubwabwo ari inzira ya quantum yo guhuza electron na phononi, ishobora gutuma quantum ihindura ingano y’ingufu za electron binyuze mu gushushanya lazeri ikwiye, no kubona imiyoboro mishya ya electron transition kugira ngo itange uburebure bushya bw’umurambararo.laser. Hashingiwe kuri iki gitekerezo, hatanzwe ihame rishya ryo gukora laser ya electron-phonon cooperative pumping, kandi itegeko ryo guhindura electron munsi yo guhuza electron-phonon rikomoka ku gufata Nd: YVO4, kristu y'ibanze ya laser, nk'ikintu gihagarariye. Muri icyo gihe, hakozwe laser ya foton-phonon cooperative pumping idafite ubukonje, ikoresha ikoranabuhanga rya gakondo rya laser diode pumping. Laser ifite uburebure budasanzwe bwa 1168nm na 1176nm. Kuri iyi ngingo, hashingiwe ku ihame ry'ibanze ryo gukora laser no guhuza electron-phonon, byagaragaye ko umusaruro w'ingano n'ubushyuhe bya laser ari ibintu bidahinduka, kimwe n'imvugo y'itegeko rya Curie muri magnetism, kandi igaragaza kandi itegeko ry'ibanze rya fiziki mu nzira y'impinduka y'icyiciro kitameze neza.

Gushyira mu bikorwa igerageza rya koperative ya photon-phononpompa laser

Uyu murimo utanga icyerekezo gishya cy’ubushakashatsi bugezweho ku buryo bwo gukora laser,fiziki ya laser, na laser ifite ingufu nyinshi, igaragaza urwego rushya rw'igishushanyo mbonera cy'ikoranabuhanga ryo kwagura ubunini bwa laser n'ubushakashatsi bwa kristu ya laser, kandi bishobora kuzana ibitekerezo bishya by'ubushakashatsi mu iterambere ryaoptike ya quantum, ubuvuzi bwa laser, ecran ya laser n'izindi nzego zijyanye n'iyo porogaramu.
