Nguva pfupi yadarika, iyo Institute of Yashandiswa Fizikisi yeStages yeScidenic yeExientic Center yekunyanyisa Kudzidza (XCELS), chirongwa chekutsvagisa chezvivakwa zvesainzi zvakanyanyisaSimba Rakakwirira Lasers. Iyo purojekiti inosanganisira kuvakwa kweiyosimba rakakwirira laserKubva pane Optical parametric chirped pulse tekinoroji mune hombe potasatium Dideuti Iri basa rinopa zvakakosha ruzivo uye nekutsvagisa pamusoro peiyo xcels chirongwa uye yayo laser masisitimu, ichitsanangura zvikumbiro uye zvinogona kukanganisa zvine chekuita neltra-yakasimba yechiedza chekudyidzana.
Iyo XCELS chirongwa chakakurudzirwa muna 2011 nechinangwa chekutanga chekuzadzisa simba repamusorolaserPurse kubuda kwe200 pw, iyo yave kusunungurwa kune mazana matanhatu em. Itslaser systeminovimba ne matatu kiyi tekinoroji:

Ultra-onedband phase inoenderana inowanikwa zvakanyanya mune akawanda makristuru uye anoshandiswa muOpcpa femtosecond lasers lasers lasers lasers. DKDP makristasi anoshandiswa nekuti ndizvo chete zvinyorwa zvinowanikwa mune zvekuita izvo zvinogona kukura kusvika makumi emasendi ehurongwa hwekutsigira hunhu hwekutsigira kukwidziridzwa kwehuwandu hwemugutalasers. Izvo zvinowanikwa kuti apo DKDP Crystal nePamhepo frequency Chiedza cheNi Lasse pulse ndeye 910 nm
Mufananidzo 1 inzvimbo yechiSchematic yeiyo xcels laser system. Mhedzisiro yekumberi yakagadzirwa nechikki chikadzi Magumo ekumberi anozivisa zvakare kuwiriraniswa kweaya mapuranga pamwe neanodiwa simba uye spatiotemporal parameter. Iyo yepakati opcpa inoshanda pane yakakwira kudzokorora chiyero (1 hz) inokwirisa iyo chiredzo provse kune makumi majee (2 mumufananidzo 1). Iyo pulse inowedzera kukwidziridzwa neiyo booster opcpa mune imwechete kilojuule danda uye yakakamurwa kuita gumi nemaviri zvidiki-matanda (4 mumufananidzo 1). Mune yekupedzisira 12 OPCPA, yega yega yegumi nembiri inokonzereswa mishonga inokwirisa kune iyo kilojoule level (5 mumufananidzo 1) uye yakazomanikidzwa ne11 compresming gratings (GC ye6 mumufananidzo 1). Iyo Acousto-Optic yakarongedzwa kurongedza firita inoshandiswa mumugumo wekumberi kuenda kuPreetly Control Boka Vhewsonion uye nekukwira zvakanyanya kuparadzaniswa, kuitira kuti uwane zvidiki zvidiki zvinokatyamadza. Iyo pulse spectrum ine chimiro chevana gumi nemaviri-kurongedza Supergauss, uye iyo spectral bandwidth supergauss Kufunga nezve kusakwana kwekupararira uye kuomerwa kweisipfupi phase phase muripo mu paramende amplifiers, iyo inotarisirwa purse upfu hwakakura ndeye makumi maviri emadhora.
Iyo xcels laser ichashandisa maviri 8-Channel ufl-2m neodymium girazi laser freepency kuyambuka Module ( Iyo yasara matatu nzira ichashandiswa seyakazvimirira nanosecond kilojoule yakadhonzwalaser zvinyorwakune zvimwe kuedza. Limited neye Option Breakdown Chikumbaridzo cheDKDP makristasi, iyo Irradiation Kuwanda kweiyo pumped pulse yakaiswa ku 1.5 GW / CM2 yezve imwe neimwe nzira uye nguva ndeye 3.5 NS.
Imwe neimwe nzira yeiyo xcels laser inoburitsa mapuranga ane simba re50 pw. Nhamba yegumi nemaviri inopa simba rakazara rekubuda kwe600 pw. Mukamuri huru yekutarisira, iyo yakanyanya kutarisisa chikamu chega chega chega chega chega mamiriro ega ari 0.44 Kana iyo pulse yeega yega ichimanikidzwa ku2,6 FS neToPT-compresming Techne Simba richawedzera kusvika 230 PW, inoenderana neyakajeka kuwanda kwe2,0
Kuti uwane zvakakura zvishoma, pa600 PW kubuda muzvikamu gumi nembiri zvichange zvakatarisa mugero weGeometry Kana chikamu chimwe nechimwe chechidhirowa chakavharirwa uye chakawiriraniswa, iyo yakabatana mhedzisiro yechiedza ichawedzerwa kusvika 3.2 × 1026 w / cm2. Kuwedzera kune iyo huru target kamuri, iyo XCELS chirongwa chinosanganisira kusvika gumi mushandisi Laboratories, imwe neimwe inogamuchira imwe kana kupfuura matanda ekuedza. Uchishandisa iyi yakasimba kwazvo yechiedza munda, iyo xcels purojekiti inoronga kuita zvekuedza mumapoka mana: Quantum Electrodynamics matanho eakadzika minda yakasimba laser; Kugadzirwa uye kukurumidza kwezvikamu; Chizvarwa chechipiri electromagnetic radiation; Laboratory nyeredzi
Fig. 2 Kutarisa Geometry mukamuri huru tarisiro. Kujekesa, girazi remugiramu redanda 6 rakagadzirirwa pachena, uye iyo yekuisa uye inobuda matanda anoratidza chete nzira mbiri 1 ne7
Mufananidzo 3 unoratidza spatial dhizaini yenzvimbo yega yega inoshanda yeiyo xcels laser system mune yekuedza kuvaka. Magetsi, vacuum pumps, kurapwa kwemvura, kucheneswa uye mamiriro emhepo ari mukamuri repasi. Nzvimbo yekuvaka yakazara inopfuura makumi maviri nemana m2. Iko kuzere kwesimba kwekushandisa kwave kuita anenge 7.5 mw. Chivakwa chekuedza chinovimbisa chine chimiro chemukati chemuviri uye chikamu chekunze, chimwe nechimwe chakavakwa pane maviri akashongedzwa nheyo. Vacuum uye kumwe kusiririsa-kudzidzira masisitimu kwakaiswa pane vibrate-isina kujairika nheyo, zvekuti iyo yekuvhiringidzwa, rutsigiro rwakaderedzwa kusvika pane isingasviki 10-10 G2 / HZ mune yehuwandu hwe1-200 hz. Uye zvakare, network yejasi reGeodesic rekesi yakaiswa muLaser Hall yekugadzirisa zvakarongeka kuongorora kwevhu nemidziyo.
Iyo xcels chirongwa ichi chinangwa chekugadzira nzvimbo yakakura yesainzi yekutsvaga yakavakirwa pane yakanyanya yepamusoro peak Simba Lasers Lasers. Chimwe chiteshi cheXcels Laser system inogona kupa yakatarisana neyakawedzera kuwanda kakawanda kupfuura 1024 w / cm2, iyo inogona kuenderera mberi ne1025 w / cm2 ine tekinoroji yekutumira. NeDipole-kutarisisa Pulses kubva pagumi nemaviri muLaser System, kushamwaridzana padyo ne1026 w / cm2 inogona kuwanikwa kunyange pasina post-compression uye phose kuvhara. Kana iyo chikamu chekunyorwa pakati nepakati kuti zvitarwe zvakakiiwa, chiedza chechiedza chichava kakawanda kumusoro. Kushandisa idzi rekodhi-kutyora pulse zvakadzama uye matsvina marara Izvi zvinotora chikamu chakasiyana mumunda wesimba-yakasimba electromagnetic munda wekuedza fizikisi.
