Ithimba lamahhala le-elektrost lase-Electron of the Chinese Academy of Sciences selithuthukile ocwaningweni lwama-leser e-elektroni ahambisanayo agcwele. Kususelwa ku-Shanghai ethambile ye-X-ray free Electron laser Facility, indlela entsha ye-Echo Harmonic Casconic Casconic Cascade Free Electron laser ehlongozwe yi-China iqinisekiswe ngempumelelo, futhi imisebe ethambile ye-X-ray enemisebe enhle itholiwe. Muva nje, imiphumela yashicilelwa e-Optica ngaphansi kwesihloko esihambisana ne-X-ray pulses kusuka kuma-harmonic enikwe amandla i-harmonic lasers yama-elektroni.
I-Electron laser ye-X-ray yamahhala ingenye yemithombo efudumele kakhulu emhlabeni. Njengamanje, iningi lama-elektroni we-Electron lase-Electron asuselwa ku-Self-arving Mechanism (I-SASE), i-SASE) i-Pull Pulth ephakeme kakhulu kanye nokwenza umsebenzi omuhle kakhulu, kodwa ukuqina komkhumbi, akuyona i-X-ray band "Laser". Enye yezinkomba ezibaluleke kakhulu zentuthuko emkhakheni we-elektroni yamahhala ye-elektroni zikhiqiza imisebe ehambisanayo ye-X-ray enekhwalithi ye-laser ejwayelekile, futhi indlela ebalulekile ukusebenzisa imbewu yangaphandle ye-laser yokusebenza ye-elektroni. Imisebe yembewu yembewu ye-elektroni yamahhala ye-elektroni izuza izici ze-laser yembewu, futhi inezimpawu ezinhle kakhulu njengokuhlangana okugcwele, ukulawulwa kwesigaba nokuvumelanisa okuqondile ne-laser yepompo yangaphandle. Kodwa-ke, ngenxa yomkhawulo we-wavelthth kanye ne-pulse yobubanzi be-laser yembewu, ukumbozwa okufushane kwe-wavelth kanye nobubanzi bokulungiswa kwembewu yembewu yembewu yangaphandle ye-elektroni ilinganiselwe. Ukuze uphinde uthuthukise ukumbozwa okufushane kwe-wavelthth ye-leeven laser yamahhala ye-elektroni, izindlela ezintsha zokusebenza ze-elektroni ezifana nezizukulwane ze-echo harmonic zithuthukiswa ngamandla emhlabeni eminyakeni yamuva.
Imbewu ye-Electron laser yamahhala ye-Electron ingenye yezindlela zobuchwepheshe eziphambili ukuthuthukisa i-High Thola i-Laser lase-Electron laseChina. Njengamanje, wonke amadivaysi amane aphezulu we-elektroni laser eChina amukele imodi yokusebenza kwembewu yangaphandle. Kususelwa eShanghai sertraviolet indawo ye-elektroniolet yamahhala ye-elektroniolet yamahhala ye-Electron lase-Electron Cacility, ososayensi bazuze ngempumelelo yohlobo lwe-Echo lwe-International Laser Typery lokuqala lwe-Electron Light Amplification kanye nohlobo lokuqala lwe-Ultraviolet Echo Saturication Free. Ukuze uqhubekele phambili ukukhuthaza i-seltron laser yamahhala ye-elektroni eya e-wavelth emfushane, iqembu labacwaningi lihlongoze ngokuzimela indlela entsha yama-elektroni laserr nge-echo harmonic cascade, futhi aqedele yonke inqubo yokuqinisekiswa kwe-econon Xanonic, futhi aqedele yonke inqubo ngokuqinisekiswa kweqembu le-x-ray. Imiphumela yocwaningo ikhombisa lokho kuqhathaniswa nendlela yokusebenza yembewu yendabuko yangaphandle, lo mshini unezici ezinhle kakhulu zokuthuthukiswa kwe-Ultrafast X-ray Pulse Gullosis Protection kanye ne-Ultrafast Pulse Gullosis, Imiphumela yokucwaninga efanele ihlinzeka ngomzila wezobuchwepheshe onokwenzeka ukuze isizukulwane sama-leser we-elektroni ahambisana ngokuphelele neqembu le-subnanometer, futhi azohlinzeka ngethuluzi elifanelekile lokucwaninga lezinkambu ze-x-ray.
I-Echo Harmonic Cascade Free Electron laser isebenza kahle kakhulu ekusebenzeni kahle: isithombe sesobunxele yimodi ye-Cascade ye-Cascade, kanti isithombe esifanele yimodi ye-echo harmonic cascade
Ukulungiswa kobude be-X-ray Pulse kanye ne-Ultrafast Pulse Genusse kungabonakala nge-Echo Harmonic Cascade
