Iterambere ryakozwe mubushakashatsi bwuzuye bwuzuye bwa laser laser

Itsinda rya Electron Laser ryubusa ryishuri ryubumenyi ryubushinwa ryateye imbere mubushakashatsi bwibikoresho bya elegitoroniki byubusa.Hashingiwe kuri Shanghai Soft X-ray Yubusa ya Electron Laser Facilité, uburyo bushya bwa echo harmonic cascade yubusa ya elegitoroniki ya elegitoroniki yatanzwe nubushinwa bwaragenzuwe neza, kandi imirasire yoroheje ya X-ray hamwe n’imikorere myiza yabonetse.Vuba aha, Ibisubizo byasohotse muri Optica ku mutwe wa Coherent na ultra-bigufi byoroshye X-ray pulses biva muri echo-ishoboye guhuza cascade ya elegitoroniki yubusa.

Lazeri ya X-ray yubusa ni imwe mumasoko yateye imbere kwisi.Kugeza ubu, ibyinshi mu byuma mpuzamahanga bya X-ray byubusa bishingiye kuri elegitoronike yisanzuye yifashisha uburyo bwo kwangiza ibyuka byangiza (SASE), SASE ifite umucyo mwinshi cyane kandi urwego rwa femto ultra-short pulse ubugari nibindi bikorwa byiza, ariko SASE vibration n'urusaku, guhuza no gutuza kw'imishwarara yayo ntabwo ari hejuru, ntabwo itsinda rya X-ray “laser”.Bumwe mu buryo bwingenzi bwiterambere mubyerekeranye niterambere rya elegitoroniki yubuntu mpuzamahanga ni ugutanga imirasire ya X-ray yuzuye hamwe nubwiza busanzwe bwa lazeri, kandi inzira yingenzi ni ugukoresha imbuto ziva hanze ya elegitoronike ikora.Imirasire yimbuto yo hanze ya elegitoroniki yubusa iragwa ibiranga imbuto ya laser, kandi ifite ibintu byiza cyane nko guhuza byuzuye, kugenzura ibyiciro no guhuza neza na pompe yo hanze.Nyamara, kubera kugabanuka kwuburebure bwumurambararo nubugari bwimbuto ya lazeri yimbuto, ubwinshi bwumurambararo hamwe nuburebure bwimisemburo yo guhinduranya imbuto yo hanze ya elegitoroniki yubusa.Kugirango turusheho kwagura uburebure buke bwikwirakwizwa ryimbuto zo hanze ya elegitoroniki yubusa, uburyo bushya bwa elegitoronike yubusa nka echo harmonic generation iratera imbere cyane kwisi mumyaka yashize.

Imbuto yo hanze yubusa ya elegitoronike ni imwe mu nzira zingenzi za tekiniki zo guteza imbere inyungu za elegitoroniki yubusa mu Bushinwa.Kugeza ubu, ibikoresho byose uko ari bine byunguka ibikoresho bya elegitoroniki ya laser mu Bushinwa byakoresheje uburyo bwo gukora imbuto zo hanze.Hashingiwe kuri Shanghai Deep Ultraviolet Free Electron Laser Facility hamwe na Shanghai Soft X-ray Yubusa ya Electron Laser, abahanga mu bya siyansi bagiye bagera ku ntera mpuzamahanga ya mbere ya echo yubuntu ya elegitoroniki ya laser yamashanyarazi ndetse nubwambere bwa ultraviolet echo yubwoko bwa elegitoronike yuzuye.Mu rwego rwo kurushaho guteza imbere imbuto ya elegitoroniki yubusa ku burebure buke, itsinda ry’ubushakashatsi ryigenga ryigenga ryashyizeho uburyo bushya bwa lazeri yubusa ya elegitoronike yubusa hamwe na echo garmonic caskade, yemejwe na Shanghai Soft X-ray Free electron Laser as gahunda shingiro, kandi yarangije inzira yose kuva kugenzura kugenzura kugeza kumurabyo urumuri rworoshye X-ray band.Ibisubizo byubushakashatsi byerekana ko ugereranije nuburyo busanzwe bwo gukoresha imbuto zo hanze, ubu buryo bufite ibintu byiza cyane byerekana, binyuze mu kwemeza abashakashatsi mu iterambere ryigenga ry’ikoranabuhanga ryisuzumisha rya ultrafast X-ray (https://doi.org/10.1016 /j.fmre.Ibisubizo byubushakashatsi bireba bitanga inzira ya tekiniki ishoboka yo kubyara amashanyarazi yuzuye ya elegitoronike yubusa mu itsinda rya subnanometero, kandi izatanga igikoresho cyiza cyubushakashatsi kubijyanye na X-ray idafite umurongo wa optique na chimie yumubiri.

Echo harmonic cascade yubusa ya elegitoroniki ya laser ifite imikorere itangaje: ishusho yibumoso nuburyo busanzwe bwa caskade, kandi ishusho iburyo nuburyo bwa echo ihuza casque

X-ray pulse uburebure buringaniye hamwe na ultrafast pulse kubyara birashobora kugerwaho na echo harmonic cascade
