ʻO ka wā e hiki mai ana o ka ultrafast precision machining

ʻO ka mīkini pololei kahi mea nui o ka hana laser. Ua hoʻomohala ʻia mai nā lasers nanosecond solid green/ultraviolet a hiki i nā lasers picosecond a me femtosecond, a ʻo nā lasers ultrafast ke kumu nui. He aha ka mea e hiki mai ana i ka hoʻomohala ʻana o ka ultrafast precision machining?

ʻO nā laser ultrafast ka mea mua i hahai i ke ala ʻenehana laser solid-state. Loaʻa i nā lasers solid-state nā hiʻohiʻona o ka mana puka kiʻekiʻe, kūpaʻa kiʻekiʻe a me ka mana maikaʻi. ʻO lākou ka hoʻomau hou ʻana o nā lasers solid-state nanosecond/sub-nanosecond, no laila, ʻo ka picosecond femtosecond solid-state lasers e hoʻololi i nā nanoseconds solid-state lasers. Ua kaulana nā lasers fiber, ua neʻe pū nā lasers ultrafast i ke kuhikuhi o nā lasers fiber, a ua puka wikiwiki nā laser fiber picosecond/femtosecond, e hoʻokūkū ana me nā laser ultrafast paʻa.

ʻO kahi hiʻohiʻona nui o nā lasers ultrafast ka hoʻonui ʻana mai ka infrared i ka ultraviolet. ʻO ka hana laser picosecond infrared he hopena kūpono loa i ka ʻoki aniani a me ka ʻeli ʻana, nā substrates seramika, ka ʻoki ʻana i ka wafer, etc. Eia naʻe, hiki i ke kukui ultraviolet ma lalo o ka hoʻomaikaʻi ʻana o nā puʻupuʻu ultra-short hiki ke hoʻokō i ka "hoʻoponopono anuanu" i ka ʻoi loa, a ʻo ka kuʻi ʻana a me ka ʻoki ʻana i nā mea i aneane ʻaʻohe hōʻailona wela, e loaʻa ana i ka hana kūpono.

ʻO ke ʻano hoʻonui ʻenehana o ka laser pulse ultra-short e hoʻonui i ka mana , mai 3 watts a me 5 watts i nā lā mua a hiki i ka pae 100 watt o kēia manawa. I kēia manawa, hoʻohana maʻamau ka hoʻoponopono pololei ʻana i ka mākeke 20 watts a 50 watts o ka mana. A ua hoʻomaka kahi hui Kelemania e hoʻoponopono i ka pilikia o nā lasers ultrafast-level kilowatt. S&ʻO kahi mea hoʻoheheʻe laser ultrafast hiki i ka moʻo ke hoʻokō i nā pono ʻoluʻolu o ka hapa nui o nā lasers ultrafast ma ka mākeke, a hoʻonui iā S&ʻO kahi laina huahana chiller e like me nā loli mākeke.

Hoʻopilikia ʻia e nā mea e like me COVID-19 a me ka ʻike ʻole o ka ʻoihana waiwai, e lohi ka noi no nā mea uila e like me nā wati a me nā papa i ka makahiki 2022, a e emi ana ka noi no nā laser ultrafast i PCB (printed circuit board), nā paneli hōʻike a me nā LED. ʻO ka pōʻai wale nō a me nā māla chip i alakaʻi ʻia, a ua loaʻa ka ultrafast laser precision machining i nā pilikia ulu.

ʻO ke ala i waho no nā laser ultrafast e hoʻonui i ka mana a hoʻomohala i nā hiʻohiʻona noiʻi hou aʻe. E lilo ana nā haneli-watt picoseconds i mea maʻamau i ka wā e hiki mai ana. Hiki i nā laser ikehu pulse kiʻekiʻe ke hiki ke hana i nā mea hiki ke hana, e like me ka ʻoki ʻana a me ka ʻeli ʻana i ke aniani a hiki i ka 8 mm mānoanoa. ʻAʻohe pilikia wela ka UV picosecond laser a ua kūpono ia no ka hoʻoponopono ʻana i nā mea koʻikoʻi, e like me ka ʻoki ʻana i nā stents a me nā huahana olakino koʻikoʻi.

I ka hui ʻana o nā huahana uila a me ka hana ʻana, aerospace, biomedical, semiconductor wafer a me nā ʻoihana ʻē aʻe, e nui ka nui o nā koi machining precision no nā ʻāpana, a ʻo ka hoʻoili laser non-contact ka mea maikaʻi loa. Ke piʻi aʻe ka ʻoihana waiwai, e hoʻi hou ka noi o nā laser ultrafast i ke ala o ka ulu kiʻekiʻe.
