Femtosecond titanium lasers miyala yamtengo wapatali imakhala ndi mfundo zazikuluzikulu zogwirira ntchito

Femtosecond laser ndi laser yomwe imagwira ntchito m'mapulses ndi nthawi yochepa kwambiri (10-15s) ndi mphamvu yapamwamba kwambiri. Sizimangotipatsa mwayi wopeza nthawi yayitali kwambiri komanso, chifukwa cha mphamvu zake zapamwamba, zapangidwa kwambiri m'mafakitale osiyanasiyana.

Thefemtosecond titanium mwala wamtengo wapatali laser, yomwe imakhala ndi femtosecond laser oscillator ndi femtosecond laser amplifier, ndi laser yomwe imagwiritsidwa ntchito kwambiri pa mapulogalamu omwe amatha kupanga ma pulses a femtosecond-scaled. Kupyolera mu mfundo yodzitsekera yokha yamiyala yamtengo wapatali ya titaniyamundi ukadaulo wapadziko lonse lapansi wotsogola wa chirped pulse amplification (CPA), ndizotheka kupanga mwachindunji ma pulses a laser a femtoseconds ochepa ndi mphamvu yayikulu kwambiri ya terawatts.

Pamene kugwiritsidwa ntchito kwa ma lasers a femtosecond kwafalikira kwambiri m'magawo osiyanasiyana, ma lasers ndi matekinoloje omwe amatha kupanga ma femtoseconds adakhalanso ndi mibadwo ingapo yaukadaulo. Kuchokera ku ma laser a utoto kupita ku ma laser olimba, kuchokera ku Q-modulation kupita kuukadaulo wokhoma, komanso kugwiritsa ntchito ukadaulo wodzitsekera wodzitsekera womwe ungathe kupanga ma pulse aafupi masiku ano, ukadaulo wa ultrashort pulse wapangidwa modumphadumpha pang'onopang'ono. zaka zingapo. Mwa iwo,titaniyamu-doped safiro lasersndi ukadaulo wodzitsekera wodzitsekera ndi nkhani yotentha kwambiri muukadaulo wa ultrashort pulse.

Popeza yotakata fluorescence sipekitiramu watitaniyamu-doped safiro makhiristo, ngati mode longitudinal wa laser zokhoma, theoretically akhoza mwachindunji kutulutsa femtoseconds angapo kugunda linanena bungwe popanda kufunika kusankha wina zimachitika m'lifupi psinjika luso, amene palibe laser ena. Ku China, kafukufuku ndi kugwiritsa ntchito titaniyamu-doped safiro lasers, ngakhale pakhala pali chitukuko chachikulu, palasers miyala yamtengo wapatali ya titaniyamum’mabuku achi China ndi oŵerengedwa ndi ochepa kwambiri. Pepala ili ndiShanghai Xinkehui New Material Co., Ltd ikupereka kufotokoza mwadongosolo pa mfundo yogwira ntchito ya titaniyamu mwala wamtengo wapatali wa laser kuchokera ku titaniyamu mwala wamtengo wapatali wa laser oscillator, titaniyamu-doped safiro amapindula, mfundo yodzitsekera, kubalalitsidwa, ndi amplifier yake ya titaniyamu.

Chifukwa chake, cholinga cha pepalali ndikukhalabe ndi chiwonetsero chonse, chachindunji, chozama chalasers femtosecond, mfundo zawo zogwirira ntchito, chikhalidwe, ndi kugwiritsa ntchito chidule chachidule, chomwe chimagwiritsidwa ntchito kupititsa patsogolo chidziwitso cha femtosecondlasers miyala yamtengo wapatali ya titaniyamu.

Pambuyo pake tipitiliza kukufotokozerani zambiri zokhudzana ndi laser crystal, mutha kutimvetsera nthawi zonse, ngati mukufuna, chonde lemberani ogulitsa athu!
