Tsogolo la makina olondola kwambiri

Kukonza makina molondola ndi gawo lofunika kwambiri popanga laser. Kwayamba kuyambira pa ma lasers oyambilira olimba a nanosecond green/ultraviolet mpaka ma lasers a picosecond ndi femtosecond, ndipo tsopano ma lasers othamanga kwambiri ndi omwe amagwiritsidwa ntchito kwambiri. Kodi njira yopangira makina othamanga kwambiri idzakhala yotani mtsogolo?

Ma laser othamanga kwambiri anali oyamba kutsatira njira yaukadaulo wa laser yolimba. Ma laser okhazikika ali ndi mawonekedwe a mphamvu yotulutsa kwambiri, kukhazikika kwakukulu komanso kulamulira bwino. Ndi kupitiliza kukweza kwa ma laser okhazikika a nanosecond/sub-nanosecond, kotero ma laser okhazikika a picosecond femtosecond amalowa m'malo mwa ma laser okhazikika a nanosecond ndi omveka bwino. Ma laser othamanga kwambiri ndi otchuka, ma laser othamanga kwambiri nawonso asunthira kunjira ya ma laser othamanga, ndipo ma laser othamanga a picosecond/femtosecond atuluka mwachangu, akupikisana ndi ma laser okhazikika a ultrafast.

Mbali yofunika kwambiri ya ma laser othamanga kwambiri ndi kusinthidwa kuchokera ku infrared kupita ku ultraviolet. Kukonza ma laser a picosecond a infrared kumakhala ndi zotsatira zabwino kwambiri pakudula ndi kuboola magalasi, ma ceramic substrates, kudula ma wafer, ndi zina zotero. Komabe, kuwala kwa ultraviolet komwe kumadalitsidwa ndi ma pulses afupiafupi kumatha "kukonza kozizira" kwambiri, ndipo kuboola ndi kudula pazinthuzo sikuli ndi zizindikiro zoyaka, zomwe zimapangitsa kuti zikhale bwino kwambiri.

Kukula kwa ukadaulo wa laser ya pulse yochepa kwambiri ndikuwonjezera mphamvu , kuyambira ma watts atatu ndi ma watts asanu m'masiku oyambirira mpaka mulingo wa ma watts 100 omwe alipo pano. Pakadali pano, kukonza molondola pamsika nthawi zambiri kumagwiritsa ntchito ma watts 20 mpaka 50. Ndipo bungwe lina la ku Germany layamba kuthana ndi vuto la ma laser othamanga kwambiri a kilowatt. S&A choziziritsira cha laser chothamanga kwambiri Ma laser ambiri othamanga kwambiri pamsika amatha kukwaniritsa zosowa zoziziritsa za ma laser ambiri othamanga kwambiri pamsika, ndikuwonjezera mzere wazinthu zozizira za S&A malinga ndi kusintha kwa msika.

Chifukwa cha zinthu monga COVID-19 komanso kusakhazikika kwachuma, kufunikira kwa zida zamagetsi monga mawotchi ndi mapiritsi kudzachepa mu 2022, ndipo kufunikira kwa ma laser othamanga kwambiri mu PCB (bolodi yosindikizidwa), ma panelo owonetsera ndi ma LED kudzachepa. Malo ozungulira ndi ma chip okha ndi omwe ayendetsedwa, ndipo makina olondola kwambiri a laser othamanga kwambiri akumana ndi zovuta zokulira.

Njira yothetsera vutoli ndi kuwonjezera mphamvu ndikupanga njira zina zogwiritsira ntchito. Ma picoseconds zana limodzi adzakhala okhazikika mtsogolomu. Ma lasers obwerezabwereza komanso mphamvu zambiri zogunda zimathandiza kuti zinthu ziyende bwino kwambiri, monga kudula ndi kuboola galasi mpaka makulidwe a 8 mm. Laser ya UV picosecond ilibe mphamvu yotenthetsera ndipo ndi yoyenera kukonza zinthu zomwe zimakhala zovuta kwambiri, monga kudula ma stent ndi zinthu zina zamankhwala zomwe zimakhala zovuta kwambiri.

Mu kupanga ndi kupanga zinthu zamagetsi, ndege, zamankhwala, semiconductor wafer ndi mafakitale ena, padzakhala zofunikira zambiri zogwiritsira ntchito makina molondola pazinthu zina, ndipo kukonza laser kosakhudzana ndi kukhudzana ndi chinthu kudzakhala chisankho chabwino kwambiri. Pamene chilengedwe cha zachuma chikuyamba, kugwiritsa ntchito ma laser othamanga kwambiri kudzabwerera ku njira yakukula kwakukulu.
