Hom-cov ntawv xauv Laser, Fais Fab Lub Zog Siab Ultrafast laser

Muaj Zog HemTosecondlaserMuaj cov ntawv thov zoo muaj nuj nqis rau hauv kev tshawb fawb thiab kev tshawb fawb xws li Terahertz tiam, attosecond pulse thiab cov zaus ntsuas zuag ntsis.Mod-xauv cov lasersRaws li kev coj ua hauv cov ntawv xov xwm yog txwv los ntawm thermal lensing nyhuv ntawm lub zog siab, thiab tam sim no qhov tsim nyog tso zis zog yog li 20 w.

Nyias daim ntawv laser siv ntau lub taub ntim qauv kom muaj kev cuam tshuam covLub Teeb NtsuasTxhawm rau cov ntawv tau nce nruab nrab nrog cov tuab ntawm 100 microns rau cov kev ua haujlwm siab tso kua mis. Cov tuab kawg nkaus uas tau txais qhov nruab nrab sib xyaw nrog cov thev naus laus zis ntau dhau ntawm cov nyhuv thermal thiab tuaj yeem ua tiav lub zog siab dua femtosecond pultosecond pultosecond pultosecond pultosecond pultosecond pulse cov zis.
Wafer oscillator ua ke nrog Kerr lens hom kev siv tshuab-txhav nias yog lub ntsiab lus muaj zog ntawm cov kev txiav txim ntawm femtosecond.

Ib pab neeg ntawm cov kws tshawb fawb los ntawm Suav Academer ntawm Sciency tsim thiab tsim cov ntawv lock-cov thawv laser nrog lub zog siab tshaj plaws nrog lub zog siab tshaj plaws thiab ib leeg Mem tes zog hauv Suav teb.
Raws li lub hauv paus ntsiab lus ntawm Kerr lens hom -king thiab qhov kev tshawb fawb ua ntej tsim qauv ntawm kev hloov kho lub sijhawm thaum lub sijhawm ntsuas phoo Thiab kev ua haujlwm txuas ntxiv, thiab paub tseeb tias kab noj hniav hom voj voos yuav raug txo los ntawm ntau dua 7% tom qab xauv.

Tom qab ntawd, coj los ntawm kev tsim qauv, pab pawg tshawb fawb tsim thiab tsim cov twj tso kua mis-cov duab kaw (Daim duab 2) Raws li cov neeg siv lub sijhawm (FIG.) Tso zis nrog lub zog nruab nrab ntawm 11.78W, ib lub mem tes dav ntawm 24,7 fs thiab ib mem tes mem tes ntawm 0.143j ntawm 72 w nqus sijhawm. Qhov dav ntawm cov tso zis pulse thiab qhov sib txawv ntawm hom intracavity yog nyob rau hauv kev pom zoo nrog cov txiaj ntsig simulation.

Txhawm rau txhawm rau txhim kho cov zis hluav taws xob ntawm lub laser, pab pawg tshawb fawb nce lub vojvoog, thiab nplua-ticked lub kerr nruab nrab thickness thiab thib ob-xaj dispersion. Thaum lub twj tso kua mis tau teeb tsa rau 94 W, cov hluav taws xob nruab nrab hluav taws xob tau nce rau 22.33 W, thiab cov mem tes dav yog 0.28 μJ.

Txhawm rau kom ntxiv cov zis zog, cov pab neeg tshawb fawb yuav nce ntxiv ntawm lub tshuab hluav taws xob uas muaj kev cuam tshuam nrog huab cua tsis zoo thiab cov huab cua dispersion.
