ʻO ka laser UV kahi ʻano laser me ka nalu 355nm. Ma muli o kona nalu pōkole a me ka laulā pulse haiki, hiki i ka laser UV ke hana i kahi kiko liʻiliʻi loa a mālama i ka wahi liʻiliʻi loa e hoʻopilikia ana i ka wela. No laila, ua kapa ʻia hoʻi ʻo "ka hana anu". ʻO kēia mau hiʻohiʻona e hiki ai i ka laser UV ke hana pololei loa i ka hana ʻana me ka pale ʻana i ka deformation o nā mea.
I kēia mau lā, ʻoiai ke koi nui nei nā noi ʻoihana i ka pono o ka hana laser, ke koho nui ʻia nei ka laser UV 10W+ nanosecond e ka poʻe he nui. No laila, no nā mea hana laser UV, ʻo ka hoʻomohala ʻana i ka mana kiʻekiʻe, ka pulse haiki, ka pinepine pinepine kiʻekiʻe o ka mana medium-high nanosecond UV laser e lilo i pahuhopu nui e hoʻokūkū ai ma ka mākeke.
Hoʻomaopopo ka laser UV i ka hana ʻana ma ka luku pololei ʻana i nā pilina kemika e hoʻopili ai i nā ʻāpana atom o ka mea. ʻAʻole e hoʻomehana kēia kaʻina hana i nā mea a puni, no laila he ʻano hana "anuanu". Eia kekahi, hiki i ka hapa nui o nā mea ke omo i ka mālamalama ultraviolet, no laila hiki i ka laser UV ke hana i nā mea i hiki ʻole i ka infrared a i ʻole nā kumu laser ʻike ʻia ke hana. Hoʻohana nui ʻia ka laser UV mana kiʻekiʻe ma nā mākeke kiʻekiʻe e pono ai ka hana pololei kiʻekiʻe, me ka wili/ʻoki ʻana o FPCB a me PCB, ka wili/scribing o nā mea keramika, ka ʻoki ʻana i ke aniani/sapphire, ka scribing o ka ʻoki wafer o ke aniani kūikawā a me ka māka laser.
Mai ka makahiki 2016, ua ulu wikiwiki ka mākeke laser UV kūloko. Ke lawe nei ʻo Trumf, Coherent, Spectra-Physics a me nā ʻoihana haole ʻē aʻe i ka mākeke kiʻekiʻe. No nā lama kūloko, ʻo Huaray, Bellin, Inngu, RFH, Inno, Gain Laser ka helu no 90% o ka māhele mākeke ma ka mākeke laser UV kūloko.
Ke ʻimi nei nā ʻāina nui o ka honua i ka ʻenehana holomua loa ma ke ʻano he wahi hoʻomohala hou. A ʻo Kina ka ʻenehana 5G alakaʻi e hiki ke hoʻokūkū me nā ʻāina ʻEulopa, ʻAmelika Hui Pū ʻIa a me Iapana. ʻO 2019 ka makahiki no ke kūʻai mua ʻana o ka ʻenehana 5G ma ka home a i kēia makahiki ua lawe mai ka ʻenehana 5G i ka nui o ka ikehu i nā mea uila mea kūʻai.
I kēia mau lā, ʻoi aku ma mua o 1 biliona mau mea hoʻohana kelepona paʻalima ma Kina a ua komo i ke au kelepona akamai. Ke nānā nei i hope i ka hoʻomohala ʻana o ke kelepona akamai ma Kina, ʻo ka wā ulu wikiwiki loa ʻo 2010-2015. I kēia wā, ua ulu ka hōʻailona kamaʻilio mai 2G a i 3G a me 4G a i kēia manawa ʻo 5G a ke piʻi nei ke koi o nā kelepona akamai, nā papa, nā huahana hiki ke komo, kahi i lawe mai i kahi manawa kūpono nui i ka ʻoihana hana laser. I kēia manawa, ke piʻi nei ke koi o ka laser UV a me ka laser wikiwiki loa.
Ma ke ʻano spectrum, hiki ke hoʻokaʻawale ʻia ka laser i loko o ka laser infrared, ka laser ʻōmaʻomaʻo, ka laser UV a me ka laser polū. Ma ka manawa pulse, hiki ke hoʻokaʻawale ʻia ka laser i loko o ka laser microsecond, ka laser nanosecond, ka laser picosecond a me ka laser femtosecond. Hoʻokō ʻia ka laser UV ma o ke kolu o ka hanauna harmonic o ka laser infrared, no laila ʻoi aku ke kumukūʻai a ʻoi aku ka paʻakikī. I kēia mau lā, ua oʻo mua ka ʻenehana laser nanosecond UV o nā mea hana laser kūloko a ua lawe piha ʻia ka mākeke laser 2-20W nanosecond UV e nā mea hana kūloko. I nā makahiki ʻelua i hala iho nei, ua hoʻokūkū loa ka mākeke laser UV, no laila ua emi ke kumukūʻai, kahi e ʻike ai ka poʻe he nui i nā pono o ka hana laser UV. E like me ka laser infrared, ʻo ka laser UV ma ke ʻano he kumu wela o ka hana pololei kiʻekiʻe he ʻelua mau ʻano hoʻomohala: ka mana kiʻekiʻe a me ka pulse pōkole.
I ka hana maoli ʻana, he mea koi nui ke kūpaʻa o ka mana a me ke kūpaʻa o ka pulse o ka laser UV. No laila, he mea pono e hoʻolako me kahi ʻōnaehana hoʻoluʻu wai hilinaʻi loa. I kēia manawa, ua lako ka hapa nui o nā lasers 3W+ UV me nā ʻōnaehana hoʻoluʻu wai e hōʻoia i ka loaʻa ʻana o ka laser UV i ka kaohi mahana pololei. ʻOiai ʻo ka laser nanosecond UV ke mea pāʻani nui ma ka mākeke laser UV, e hoʻomau ka ulu ʻana o ke koi o ka ʻōnaehana hoʻoluʻu wai.
Ma ke ʻano he mea hoʻolako hoʻonā hoʻoluʻu laser, ua hoʻolaha ʻo S&A Teyu i nā mea hoʻoluʻu wai i hoʻolālā kūikawā ʻia no ka laser UV i kekahi mau makahiki i hala aku nei a lawe i ka māhele mākeke nui loa i ka hoʻohana ʻana i ka hoʻoluʻu ʻana o ka laser UV nanosecond. Ua ʻike maikaʻi ʻia nā mea hoʻoluʻu laser UV recirculating RUMP, CWUL a me CWUP e nā mea hoʻohana mai nā wahi a puni o ka honua.
