Kuti mumvetsetse laser ultrafast, munthu ayenera kudziwa chomwe laser pulse ndi. Kugunda kwa laser kumatanthawuza kuti pulse laser imatulutsa kugunda kwa kuwala. Kunena mwachidule, ngati tisunga nyali yoyaka, ndiye kuti nyaliyo ikugwira ntchito mosalekeza. Ngati tiyatsa nyali ndikuzimitsa nthawi yomweyo, ndiye kuti kutulutsa mphamvu kumatuluka.
Kugunda kwa laser kumatha kukhala kwaufupi kwambiri, kufika nanosecond, picosecond ndi femtosecond level. Mwachitsanzo, pa picosecond laser pulse, imatha kutulutsa kugunda kwamphamvu kopitilira 1mlliion biliyoni ndipo izi zimatchedwa ultrafast laser.
Kodi ubwino wa ultrafast laser ndi chiyani? Pamene mphamvu ya laser ikuyang'ana pakanthawi kochepa, mphamvu yamtundu umodzi ndi mphamvu yapamwamba imakhala yokwera kwambiri komanso yayikulu. Chifukwa chake, pakukonza pazida, laser ya ultrafast sichimayambitsa kusungunuka kapena kutulutsa kosalekeza kuzinthu zomwe zimakhala choncho ngati m'lifupi mwake komanso kutsika kwamphamvu kwa laser kumagwiritsidwa ntchito. Izi zikutanthauza kuti ultrafast laser imatha kusintha kwambiri khalidwe la processing.
M'mafakitale, nthawi zambiri timayika ma laser ngati laser wave wave, quasi-continuous wave laser, short pulse laser ndi ultrashort pulse laser. Mopitiriza yoweyula laser chimagwiritsidwa ntchito laser kudula, laser kuwotcherera, laser cladding ndi laser chosema. Quasi-continuous wave laser ndi yoyenera kubowola laser ndi chithandizo cha kutentha. Short pulse laser ndiyoyenera kuyika chizindikiro cha laser, kubowola laser, zamankhwala ndi zamankhwala. Ultrashort kugunda laser angagwiritsidwe ntchito ngakhale mafakitale apamwamba, monga processing mwatsatanetsatane, kafukufuku wa sayansi, zachipatala, madera ankhondo.
Nthawi yomwe laser ultrafast imalumikizana ndi zinthu ndi yaifupi kwambiri, kotero sizingabweretse kutentha kwazinthu zozungulira. Choncho, ultrafast laser amatchedwanso "cold processing". Ultrafast laser imathanso kugwira ntchito pazinthu zamtundu uliwonse, kuphatikiza zitsulo, semiconductor, diamondi, safiro, zoumba, polima, utomoni, filimu woonda, galasi, batire ya dzuwa ndi zina zotero.
Ndi kufunikira kwa kupanga kwapamwamba kwambiri, kupanga mwanzeru komanso kuchulukitsidwa kwachangu kwambiri, ukadaulo wa laser wa ultrafast udzakumana ndi mwayi watsopano mtsogolomu.
Monga woyimira chida chopangira cholondola, laser ya ultrafast iyenera kuziziritsidwa bwino kuti ikhale yabwino kwambiri. S&A Teyu mini recirculating chiller CWUP-20, yomwe imadziwikanso kuti ndiyolondola kwambiri, ndiyomwe idasankhidwa kwambiri ndi ogwiritsa ntchito laser othamanga kwambiri. Izi zili choncho chifukwa chotenthetsera madzi cha laser chofulumira kwambiri chimakhala ndi + -0.1 digiri C kukhazikika kwa kutentha komanso kukonza kochepa komanso kupulumutsa mphamvu. Kuphatikiza apo, ultrafast laser mini recirculating chiller CWUP-20 ndiyosavuta kugwiritsa ntchito, chifukwa malangizo ogwiritsira ntchito ndi osavuta kumva. Kuti mudziwe zambiri za chiller ichi, dinani
