Chikwata cheMahara erekitironi Laser cheChinese Academy yeSainzi chafambira mberi mukutsvagisa kwemarekitironi emahara emahara lasers.Zvichienderana neShanghai Soft X-ray Yemahara Electron Laser Facility, iyo nyowani nyowani echo harmonic cascade yemahara erekitironi laser yakatsanangurwa neChina yakasimbiswa zvakabudirira, uye yakapfava X-ray inobatana mwaranzi ine mashandiro akanaka yawanikwa.Munguva pfupi yapfuura, Mhedzisiro yakaburitswa muOptica pasi pezita rekuti Coherent uye Ultra-pfupi yakapfava X-ray pulses kubva echo-enabled harmonic cascade yemahara maelectron lasers.
Iyo X-ray yemahara erekitironi laser ndiyo imwe yemhando yepamusoro mwenje masosi munyika.Parizvino, mazhinji epasi rose eX-ray emahara erekitironi lasers akavakirwa pane inozvisimudzira inongoerekana yaburitsa mashandiro (SASE), SASE ine yakanyanya kupenya kupenya uye femto level yekupedzisira-pfupi pulse upamhi uye kumwe kuita kwakanakisa, asi SASE vibration. neruzha, kuwirirana uye kugadzikana kweiyo radiation pulse haisi yakakwirira, haisi X-ray band "laser".Imwe yeanonyanya kukosha nzira dzekusimudzira mumunda wepasi rose emahara erekitironi laser kugadzira yakanyatsoenderana X-ray mwaranzi neyakajairwa laser mhando, uye yakakosha nzira ndeye kushandisa yekunze mbeu yemahara erekitironi laser inoshanda mashandiro.Mwaranzi yemhodzi yekunze yemahara erekitironi laser inogara nhaka hunhu hwembeu laser, uye ine hunhu hwakanakisa sekubatana kwakazara, kudzora kwechikamu uye kunyatso wiriranisa neyekunze pombi laser.Nekudaro, nekuda kwekuganhurwa kwewavelength uye pulse upamhi hwembeu laser, iyo pfupi wavelength kufukidzwa uye pulse kureba kugadziridzwa kweyekunze yembeu yemahara erekitironi laser inogumira.Kuti uwedzere kuwedzera kupfupika kwewavelength yekunze kwembeu yemahara erekitironi laser, mitsva yemahara erekitironi laser inoshanda modhi senge echo harmonic chizvarwa chiri kuvandudzwa pasirese mumakore achangopfuura.
Mbeu dzekunze dzemahara erekitironi laser ndiyo imwe yenzira huru dzehunyanzvi yekuvandudza kuwana yakakwira yemahara erekitironi laser muChina.Parizvino, ese mana akakwira anowana emahara erekitironi laser zvishandiso muChina atora ekunze mbeu yekushanda maitiro.Zvichienderana neShanghai Deep Ultraviolet Yemahara erekitironi Laser Facility uye Shanghai Soft X-ray Yemahara Electron Laser Facility, masayendisiti akawana zvakatevedzana ekutanga echo mhando yemahara erekitironi laser mwenje weamplification uye yekutanga yakanyanyisa ultraviolet echo mhando yemahara erekitironi laser saturation amplification.Kuti tienderere mberi nekusimudzira iyo yekunze mbeu yemahara erekitironi laser kune ipfupi wavelength, timu yekutsvagisa yakazvimiririra nzira nyowani yemahara emahara erekitironi laser ine echo harmonic cascade, iyo yakatorwa neShanghai Soft X-ray Yemahara elekitironi Laser mudziyo se. iyo yakakosha chirongwa, uye yakapedza iyo yese maitiro kubva pamusimboti verification kusvika pakureruka kukwidziridzwa munyoro X-ray bhendi.Mhedzisiro dzetsvagiridzo dzinoratidza kuti zvichienzaniswa neyekare ekunze mbeu yemhando yekumhanyisa michina, iyi nzira ine yakanakisa spectral hunhu, kuburikidza nekutorwa kwevatsvagiri veyakazvimiririra budiriro ye Ultrafast X-ray pulse diagnostic tekinoroji (https://doi.org/10.1016 /j.fmre.2022.01.027), Kushanda kwepamusoro kweiyi nzira itsva mukudzora kureba kwepulse uye ultrafast pulse generation inosimbiswa zvakare.Mhedzisiro yakafanira yekutsvagisa inopa inogoneka tekinoroji nzira yekugadzira yakanyatsoenderana emahara erekitironi lasers mu subnanometer bhendi, uye ichapa yakanakira yekutsvagisa chishandiso kuminda yeX-ray nonlinear optics uye Ultrafast yemuviri chemistry.
Iyo echo harmonic cascade yemahara erekitironi laser ine yakanakisa spectral performance: iyo yekuruboshwe ndiyo yakajairika cascade modhi, uye iyo yekurudyi ndiyo echo harmonic cascade mode.
X-ray pulse kureba kugadziridzwa uye ultrafast pulse chizvarwa inogona kuitika ne echo harmonic cascade.
