Laser inotyaira inosarudza muganho wepamusoro weattosecond laser light source

Laser inotyaira inosarudza muganho wepamusoro welaser yeattosecondchiedza chinobva.
Parizvino,lasers dzeattosecond pulseZvinonyanya kugadzirwa kuburikidza nekugadzirwa kwemhando yepamusoro kwesimba (HHG) inotungamirwa neminda yakasimba. Hunhu hwekugadzirwa kwavo hunogona kunzwisiswa semaerekitironi ari kusanganiswa, kukwidziridzwa, uye kubatanidzwazve kuti abudise simba, nokudaro achiburitsa attosecond XUV pulses.
Saka, kubuda kweattosecond pulses kunonyanya kunzwisiswa nehupamhi hwepulse, simba, urefu hwewavelength, uye kudzokorora kwelaser inotyaira: upamhi hwepulse hupfupi hunobatsira kuparadzanisa attosecond pulses, simba rakawanda rinovandudza ionization uye kushanda zvakanaka, urefu hwewavelength hunowedzera simba re cutoff asi hunoderedza zvakanyanya kushanda kwekushandura, uye kudzokorora kwakakwirira kunovandudza chiyero chesignal-to-noise asi chinogumira nesimba re single-pulse.
Mashandisirwo akasiyana anotarisa pane zviratidzo zvakasiyana-siyana zveattosecond lasers, nokudaro zvinoenderana nesarudzo dzemagadzirirwo emhando dzakasiyana dzekutyaira.masosi elaser.
Pamashandisirwo akadai se ultrafast dynamics research uye electron microscopy, stable isolation ye attosecond pulses (IAP) inowanzoda short-pulse driving pulses uye good carrier envelope phase (CEP) control kuti iwane nguva inoshanda uye waveform controlled;
Pakuyedza kwakadai se pump-probe spectroscopy uye multi-photon ionization, high-energy kana high-flux attosecond radiation inobatsira kuvandudza efcitation/absorption efficiency, iyo inowanzo kuwanikwa pasi pesimba rekutyaira rakawanda uye avhareji yesimba rakawanda kuburikidza neHHG, uye inoda kuchengetedza phase matching inogamuchirika uye beam quality pasi pemamiriro e ionization akakwira;
Kuti pave nemwaranzi yeattosecond muhwindo reX-ray (inobatsira zvikuru pakuona mifananidzo pamwe chete uye X-ray absorption spectroscopy yakagadziriswa nenguva), mid-infrared long-wavelength driving inowanzo shandiswa kuwedzera harmonic cutoff energy uye kuwana photon energy coverage yakakwira;
Muzviyero zvinonyatsoenderana nekururama kwenhamba, zvakaita sekuverenga uye photoelectron spectroscopy, mafrequency akakwira ekudzokorora anogona kuvandudza zvakanyanya chiyero chesignal-to-noise uye kugona kwekuwana data, nepo kuderera kwe single-pulse charge/energy kunobatsira kuderedza kuganhurirwa kwemhedzisiro yespatial charge pa energy spectrum resolution.
Kuenderana pakati pemaparamita elaser yekutyaira, hunhu hwelaser yeattosecond pulse, uye zvinodiwa pakushandisa kunoratidzwa muMufananidzo 1. Kazhinji, zvinodiwa zvemaapplication zvinoramba zvichikurudzira kuvandudzwa kweparamita dzelaser yeattosecond pulse, uye nekudaro zvichitungamira kuvandudzwa kuri kuramba kuchienderera mberi kwezvivakwa uye matekinoroji akakosha elaser inokurumidza zvikurumasisitimu.
