Me ka hoʻomohala wikiwiki o ka ʻepekema a me ka ʻenehana, ua lilo nā mea hana ʻoki laser i mea nui a hoʻohana ākea ʻia i ka mākeke ʻoihana. ʻO nā mīkini ʻokiʻoki laser paʻa i ka pololei o ka ʻoki ʻana a me ka wikiwiki wikiwiki, hiki ke hoʻomaikaʻi i ka hana pono e 60% a mālama i nā kumukūʻai hou aʻe. No laila, aloha nui ʻia lākou e ka poʻe. E ke aloha, e hoʻomaopopo i nā mea hana mīkini ʻoki laser i ka palapala noi o ka mīkini ʻoki laser i ka mākeke ʻoihana.
ʻAneʻane kokoke i nā mea hao a pau ke kiʻekiʻe o ke kukui uila infrared i ka mahana wela o ka lumi. ʻO kahi laʻana, ʻo ka nui o ka absorption o ka 10.6um carbon dioxide laser he 0.5% wale nō a 10%, akā ke hoʻomālamalama kahi kukuna koʻikoʻi me ka nui o ka mana ma mua o 10 ″ W / em2 ma kahi pae hao, hiki i ke kaʻina o microseconds. Hoʻomaka ka hoʻoheheʻe o ka papa o loko. ʻO ka helu omo o ka nui o nā metala i hoʻoheheʻe ʻia e ala kiʻekiʻe, piʻi a 60% -80%. No laila, ua hoʻohana kūleʻa ʻia nā kukuna kalapona kalapona ma nā hana ʻoki metala he nui.
ʻO ka mānoanoa o ka papa kila kila hiki ke ʻoki ʻia e nā ʻōnaehana ʻoki laser hou i ʻoi aku ma mua o 20mm. Hoʻohana ʻia ka hana ʻoki kuʻi fihi ʻokiʻoki ʻia e ʻokiʻoki i nā pā kalapona kila. Hiki ke kāohi ʻia ka ʻoki i loko o kahi ākea hōʻoluʻolu, a ʻo ka ʻoki no nā pā kila lahilahi hiki ke like me ka 0,1 mm. e pili ana. ʻO ka ʻoki ʻana i kahi laser kahi hana kūpono no nā pā kila. Hiki iā ia ke kaohi i ka wahi i pā i ka wela ma waena o kahi pae liʻiliʻi, i mea e mālama ai i kāna kūpaʻa kūpaʻa. Hiki ke hoʻohana ʻia ka hapa nui o nā kila kila a me nā kila hana hao e loaʻa ai ke maikaʻi maikaʻi o ka ʻoki ʻana e ka ʻoki laser.
ʻAʻole hiki ke hoʻoheheʻe ʻia a ʻokiʻoki ʻia nā mea hoʻopili alumini a ʻokiʻoki me ka oxygen. Pono e hoʻohana i ka hana hoʻoheheʻe a me ke ʻoki. Pono kaʻokiʻana i ka laser alumini i kahi kiʻekiʻe o ka mana e lanakila ai i kona hiʻohiʻona kiʻekiʻe i ka laser wavelength 10.6um. Hiki i ka kukuna kukuna YAG me ka lōʻihi o 1.06 um ke hoʻomaikaʻi maikaʻi i ka ʻoki ʻana a me ka wikiwiki o ka ʻoki ʻana o ka laser alumini ma muli o ka nui o ka absorptivity.
Hoʻohana ʻia nā kolamu titanium a me titanium i ka ʻoihana mokulele e hoʻohana ana i ka oxygen ma ke ʻano he gas kōkua. Ke huhū nei ka hopena kemika a ʻoi aku ka wikiwiki o ka ʻoki ʻana, akā maʻalahi e hana i kahi papa oxide ma ka ʻoki a hiki i ke kumu o ka overburn. Mālama ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka ʻaukā inert ma ke ʻano he gas kōkua, hiki ke hōʻoia i ka maikaʻi o ka ʻoki.
