Urupapuro rufunze Mode Laser, Ingufu Zisumbuye Ultrafafari Laser

Imbaraga ndende femtosecondlaserifite agaciro gakomeye mubikorwa byubushakashatsi bwa siyansi ninganda zinganda nka terahertz igisekuru cya Terahertz, attosecond igisekuru cyiki gisekuru cya optique.Amavuta yo gufunga modebishingiye ku bitangazamakuru gakondo-bigarukira ku ngaruka z'imitima yubushyuhe ku bubasha bwo hejuru, kandi kuri ubu imbaraga ntarengwa zisohoka zigera kuri 20 W.

Urupapuro ruto rwa laser rukoresha imiterere ya pompe nyinshi kugirango tugaragazeUmucyokurupapuro rwiboneye hamwe nubunini bwa microns 100 kugirango binjire neza. Ubwumvikane bunini bunini bunini hamwe nikoranabuhanga ryinyuma rigabanya cyane ingaruka zingaruka zubushyuhe hamwe ningaruka zidasanzwe, kandi zishobora kugera kububasha burenze urugero PAMTOSECond Pulmos.
Ibishishwa bya Wafef byahujwe na Kerr Lens-Gufunga Technology nuburyo bukomeye bwo kubona ubugari buhebuje bwa laser bisohoka hamwe nubugari bwa femtosekond muburyo bwa femtosekond.

Igishushanyo 1 (a) 72 Optique Igishushanyo cya Optique na (b) Igishushanyo cyumubiri cya pompe module

Itsinda ry'abashakashatsi bo mu ishuri ry'ubumenyi ry'Abashinwa ryateguwe kandi ryubaka urupapuro rwa Kerr Lens rushingiye ku modoka 72. Urupapuro rufunze
Ukurikije ihame rya kerr lens Mode-Gufunga hamwe no kubara ABCD Matrix, ikipe yo gufunga imiyoboro ya Diaser, kandi yemeje ko imikorere yo gufunga 1% nyuma yo gufunga mode-gufunga.

Nyuma, iyobowe nihame ryo gushushanya, itsinda ryubushakashatsi ryateguwe kandi ryubaka renator ya Kerr (FIG. 2 Ubugari bwibisohoka pulse hamwe no gutandukana muburyo bwiza bujyanye no kumvikana neza nibisubizo byo kwigana.

Igishushanyo 2 Igishushanyo cya Schematic cyubwonko bwuzuye bwa kerr lens-yafunze yb: Yag Wafer Laser yakoresheje mubushakashatsi

Mu rwego rwo kunoza imbaraga zisohoka za laser, itsinda ry'abashakashatsi ryongereye imishinga yo kugabanuka kw'indorerwamo yibanze, kandi ihuza neza na kerr z'ubugari na kabiri. Igihe imbaraga za pompe zashyirwaga kuri 94 W, impuzandengo y'ibisohoka yiyongereye kugera kuri 22.33 W, kandi ubugari bwa Pulse bwari 394 kandi ingufu imwe y'ihungabana yari 0.28 μj.

Kugira ngo urusheho kongera umusaruro usohotse, itsinda ry'abashakashatsi rizakomeza kongera indwara yo kugabanuka kw'indorerwamo y'indorerwamo ya Concave, mu gihe ishyira revonator ahantu hafunze hafunzwe ibidukikije kugira ngo bigabanye imvururu n'ibihure.
