He aha ka laser?

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

Ma Wikipedia, ʻo A laserHe mea ia e hoʻopuka ana i ka mālamalama ma o ke kaʻina hana o ka hoʻonui ʻike ʻana ma muli o ka hoʻoulu ʻia ʻana o ka pāhawewe electromagnetic.ʻO ka huaʻōlelo "laser" he acronym ia no ka "hoʻonui māmā ma o ka hoʻoulu ʻia ʻana o ka radiation".Ua kūkulu ʻia ka laser mua ma 1960 e Theodore H. Maiman ma Hughes Research Laboratories, ma muli o ka hana theoretical e Charles Hard Townes a me Arthur Leonard Schawlow.

He ʻokoʻa ka laser mai nā kumu kukui ʻē aʻe no ka mea e hoʻopuka ana i ka mālamalama i kūlike.Hiki i ka coherence spatial ke nānā aku i kahi laser i kahi paʻa, hiki i nā noi e like me ka ʻoki laser a me ka lithography.ʻO ka hoʻopili ʻana i nā wahi e hiki ai i kahi kukuna laser ke noho haiki ma kahi mamao loa (collimation), hiki i nā noi e like me nā kuhikuhi laser a me ka lidar.Hiki i nā lasers ke loaʻa i ka pilina kino kiʻekiʻe, e hiki ai iā lākou ke hoʻokuʻu i ka mālamalama me kahi kikoʻī haiki loa.ʻO kahi ʻē aʻe, hiki ke hoʻohana ʻia ka pilina kino e hana i nā pulses ultrashort o ka māmā me kahi kikoʻī ākea akā ʻo nā lōʻihi e like me ka femtosecond.

Hoʻohana ʻia nā lasers i nā disk drive optical, nā mea paʻi laser, nā mea ʻimi barcode, nā mea hana DNA sequencing, fiber-optic, semiconducting chip manufacturing (photolithography), a me ke kamaʻilio optical free-space, ʻoki laser, a me ka mālama ʻana i ka ʻili, ka ʻoki a me nā mea hoʻoheheʻe, pūʻali koa a nā mea hoʻokō kānāwai no ka mākaʻikaʻi 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 lōʻihi o ka hoʻomohala ʻana i ka ʻenehana laser, hiki ke hoʻohana ʻia ka laser i nā noi ʻoihana ʻē aʻe, a ʻo kekahi o ka hoʻololi nui loa e hoʻohana inā no ka ʻoki ʻana i ka ʻoihana, ʻaʻohe metala ka metala a i ʻole ka ʻoihana non-metal, hoʻomaikaʻi ka mīkini ʻoki laser i ke ʻano ʻoki kuʻuna, e hoʻomaikaʻi i ka nui o ka hana pono no ka ʻoihana huahana, e like me ka lole, textile, carpet, wood, acrylic, hoʻolaha, metala, kaʻa, nā mea pono a me nā ʻoihana lako.

Ua lilo ʻo Laser i mea ʻoki maikaʻi loa no kāna mau hiʻohiʻona ʻoki kiʻekiʻe a me ka wikiwiki.

E aʻo hou i ka ʻenehana Laser
