Kuti mumvetse bwino laser yothamanga kwambiri, muyenera kudziwa tanthauzo la laser pulse. Laser pulse imatanthauza kuti laser ya pulse imatulutsa kuwala kwa kuwala. Mwachidule, ngati tisunga kuwala kwa kuwala, zikutanthauza kuti kuwala kwa kuwala kukugwira ntchito mosalekeza. Ngati tiyatsa kuwala kwa kuwala ndikuzimitsa nthawi yomweyo, zikutanthauza kuti kuwala kwa kuwala kumatulutsa.
Kugunda kwa laser kumatha kukhala kochepa kwambiri, kufika pamlingo wa nanosecond, picosecond ndi femtosecond. Mwachitsanzo, pa picosecond laser pulse, imatha kutulutsa pulse yofupika yoposa 1 miliyoni biliyoni ndipo iyi imatchedwa ultrafast laser.
Kodi ubwino wa laser wothamanga kwambiri ndi uti?
Mphamvu ya laser ikayang'ana kwambiri pakapita nthawi yochepa chonchi, mphamvu ya single pulse ndi mphamvu ya peak zidzakhala zazikulu kwambiri komanso zazikulu. Chifukwa chake, pokonza zinthuzo, ultrafast laser sidzayambitsa kusungunuka kapena kusungunuka kosalekeza kuzinthuzo zomwe nthawi zambiri zimakhala choncho ngati pulse m'lifupi ndi low intensity laser zigwiritsidwa ntchito. Izi zikutanthauza kuti ultrafast laser ikhoza kusintha kwambiri khalidwe la processing.
Mu gawo la mafakitale, nthawi zambiri timagawa laser m'magulu monga continuous wave laser, quasi-continuous wave laser, short pulse laser ndi ultrashort pulse laser. Continuous wave laser imagwiritsidwa ntchito kwambiri podula laser, kuwotcherera laser, laser cladding ndi laser engraving. Quasi-continuous wave laser ndi yoyenera kuboola laser ndi kutentha. Short pulse laser ndi yoyenera polemba laser, kuboola laser, zachipatala ndi zamankhwala. Ultrashort pulse laser ingagwiritsidwe ntchito ngakhale m'mafakitale apamwamba, monga kukonza molondola, kafukufuku wasayansi, zachipatala, madera ankhondo.
Nthawi yomwe laser yothamanga kwambiri imalumikizana ndi zinthu ndi yochepa kwambiri, kotero siibweretsa kutentha kuzinthu zozungulira. Chifukwa chake, laser yothamanga kwambiri imadziwikanso kuti "kukonza kozizira". Laser yothamanga kwambiri imathanso kugwira ntchito pazinthu zilizonse, kuphatikiza chitsulo, semiconductor, diamondi, safiro, ziwiya zadothi, polima, resin, filimu yopyapyala, galasi, batri yamagetsi ya dzuwa ndi zina zotero.
Chifukwa cha kufunikira kwa kupanga zinthu zapamwamba, kupanga zinthu mwanzeru komanso kupanga zinthu molondola kwambiri, ukadaulo wa laser wothamanga kwambiri udzakwaniritsa mwayi watsopano mtsogolomu.
Monga chida chopangira zinthu molondola, laser ya ultrafast iyenera kuziziritsidwa bwino kuti isunge bwino kwambiri. S&A Teyu mini recirculating chiller CWUP-20, yomwe imadziwikanso kuti ndi yolondola kwambiri, ndiyo yomwe imasankhidwa kwambiri ndi ogwiritsa ntchito laser ya ultrafast. Izi zili choncho chifukwa ultrafast laser yaying'ono iyi ya ultrafast water chiller ili ndi kutentha kokhazikika kwa +-0.1 digiri C komanso kusakonza kocheperako komanso kusunga mphamvu. Kuphatikiza apo, ultrafast laser mini recirculating chiller CWUP-20 ndiyosavuta kugwiritsa ntchito, chifukwa malangizo ogwiritsira ntchito ndi osavuta kumvetsetsa. Kuti mudziwe zambiri za chiller iyi, dinani https://www.teyuchiller.com/portable-water-chiller-cwup-20-for-ultrafast-laser-and-uv-laser_ul5
