He aha ka laser?

I ka pōkole, ʻo ka laser ka mālamalama i hana ʻia e ka hoʻonāukiuki ʻana o nā mea. A hiki iā mākou ke hana i nā hana he nui me kahi kukuna laser.

Ma Wikipedia, A laserhe mea hana ia e hoʻopuka i ka mālamalama ma o ke kaʻina hana o ka hoʻonui optical e pili ana i ka hoʻokuʻu ʻia ʻana o ka radiation electromagnetic. ʻO ka huaʻōlelo "laser" he acronym no "light amplification by stimulated emission of radiation". Ua kūkulu ʻia ka laser mua i ka makahiki 1960 e Theodore H. Maiman ma Hughes Research Laboratories, ma muli o ka hana kumumanaʻo na Charles Hard Townes lāua ʻo Arthur Leonard Schawlow.

ʻOkoʻa ka laser mai nā kumu kukui ʻē aʻe ma muli o ka hoʻopuka ʻana i ka mālamalama i kūlike. ʻAe ke kūlike spatial i kahi laser e kau ʻia i kahi wahi paʻa, e hiki ai i nā noi e like me ka ʻoki laser a me ka lithography. ʻAe pū ke kūlike spatial i kahi kukuna laser e noho haiki ma luna o nā mamao lōʻihi (collimation), e hiki ai i nā noi e like me nā kuhikuhi laser a me ka lidar. Hiki i nā lasers ke loaʻa ke kūlike temporal kiʻekiʻe, e hiki ai iā lākou ke hoʻopuka i ka mālamalama me kahi spectrum haiki loa. Ma kekahi ʻaoʻao, hiki ke hoʻohana ʻia ke kūlike temporal e hana i nā pulse ultrashort o ka mālamalama me kahi spectrum ākea akā ʻo ka lōʻihi e like me ka femtosecond.

Hoʻohana ʻia nā lasers i nā drive disc optical, nā mīkini paʻi laser, nā scanner barcode, nā mea hana DNA sequencing, fiber-optic, semiconducting chip manufacturing (photolithography), a me ke kamaʻilio optical free-space, ke ʻoki laser, a me nā mālama ʻili, nā mea ʻoki a me ka hoʻopili ʻana, nā mea koa a me nā mea hoʻokō kānāwai no ka māka ʻana i nā pahuhopu a me ke ana ʻana i ka laulā a me ka wikiwiki, a ma nā hōʻike kukui laser no ka leʻaleʻa.

Ma hope o ka hoʻomohala lōʻihi ʻana o ka ʻenehana laser, hiki ke hoʻohana ʻia ka laser ma nā ʻano ʻoihana like ʻole, a ʻo kekahi o nā hoʻohana kipi loa inā no ka ʻoki ʻana i ka ʻoihana, ʻaʻohe metala ka ʻoihana metala a ʻaʻole paha, hōʻano hou ka mīkini ʻoki laser i ke ʻano ʻoki kuʻuna, hoʻomaikaʻi i ka nui o ka pono hana no ka ʻoihana huahana, e like me ke kapa, ka lole, ke kāpeti, ka lāʻau, ka acrylic, ka hoʻolaha, ka hana metala, ke kaʻa, nā lako hoʻoikaika kino a me nā ʻoihana lako.

Ua lilo ka Laser i hoʻokahi o nā mea ʻoki maikaʻi loa ma muli o kona mau hiʻohiʻona ʻoki kiʻekiʻe a me ka wikiwiki.

E aʻo hou aʻe e pili ana i ka ʻenehana laser
