Amandla aphezulu we-femtosecondi-laserInenani elikhulu lesicelo ocwaningweni lwesayensi kanye nasezinkameni zezimboni ezinjenge-Terahertz Generation, i-atosecond Pulse Generation kanye ne-Optical Frequency Calk.Ama-lasers akhiyiwe modKususelwa kumidiya yendabuko ye-block-sain ikhawulelwe yithonya le-lensing eshisayo emandleni aphezulu, futhi njengamanje amandla aphezulu okukhipha acishe abe ngu-20 W.
Ishidi elishisekile leshidi lisebenzisa isakhiwo sepompo esiningi sokubonisampompaIshidi lokuthola okuphakathi nobukhulu bama-micron ayi-100 ukuze kufakwe ipompo ephezulu. Ukuthola okuphakathi okuphakathi kakhulu okuhlangene nobuchwepheshe be-backcooling kunciphisa kakhulu ithonya lomphumela we-lens we-thermali kanye nomphumela we-nonlinear, futhi ungathola amandla aphezulu we-femtosecond pulse akhipha.
Ama-Oscillator ahlanzayo ahlanganiswe nobuchwepheshe be-Kerr Lens-Lock-Lock-Lock-Locking kuyindlela esemqoka yokuthola okuphezulu kokukhishwa kwama-laser wamandla we-Laser nge-Pultosecond.

Iqembu labacwaningi abavela eChina Academy of Sciences aklanywe futhi bakha i-Kens Lens Mode-Locked Sheet Lasele esuselwa kumodyuli yepampu ye-72-Way Locked, futhi athuthukise i-Kens Lens Mode-Low Sheet Laser ngamandla aphakathi nendawo aphakathi nendawo eChina.
Ngokusekelwe kwinqubomgomo ye-Kerr Lens Mode-Lock kanye nokubalwa kwe-Interative Matrix, iqembu lokucwaninga laqala ukuhlaziya imodi yokukhiya imodi yokukhiya imodi yokukhiya imodi yokukhiya imodi yokukhiya imodi yokukhiya imodi yokukhiya.
Kamuva, ngokulandela umgomo wokwakhiwa, iqembu lokucwaninga eliklanyelwe futhi lakha i-Kens Lens Mode-Locked Resonator (Fig. 2) Isuselwa kumandla we-72 ama-FS kanye ne-pulse yamandla ka-0.14μJ ngesikhathi esingu-72 w ngesikhathi sokuposa. Ububanzi bokuphuma kokuphuma kanye nokuhlukahluka kwemodi ye-intracavity kuvumelana okuhle nemiphumela sekulingisa.

Ukuze uthuthukise amandla okukhishwa kwe-laser, iqembu lokucwaninga lenyuka imisebe ye-curvature yokugxila kwesibuko, futhi ihlelwe kahle i-kerr medium ubukhulu kanye nokuhlakazeka kwe-oda lesibili. Lapho amandla epompo ahlelelwe ku-94 W, amandla aphakathi nendawo akhuphulwa afinyelela ku-22.33 W, kanye nobubanzi be-pulse kwakungu-394 FS kanye ne-lingle Pulse Energy kwakungu-0.28 μj.
Ukuqhubeka nokwandisa amandla okukhipha, iqembu lokucwaninga lizophinde likhuphule imisebe ye-curvature yesibuko se-Mirror se-concave egxile egxile embhalweni wesibuko esigxile emhlanganweni, ngenkathi kuvalwe indawo evuthiwe ye-vacuum evaliwe ukunciphisa ithonya lokuphazamiseka komoya nokuhlakazeka komoya.
