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. Hiki i ka coherence spatial ke hiki i ka 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, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, semiconducting chip manufacturing (photolithography), a me ka free-space optical communication, laser surgery, and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and ana ana ka laulā a me ka wikiwiki, a me nā hōʻike kukui laser no ka leʻaleʻa.

Ma hope o ka lōʻihi o ka hoʻomohala ʻana o ka ʻenehana laser, hiki ke hoʻohana ʻia ka laser i nā noi ʻoihana ʻē aʻe, a ʻo kekahi o ka hoʻohana nui ʻana inā no ka ʻoki ʻana i ka ʻoihana, ʻaʻohe metala ka metala a i ʻole ka ʻoihana non-metal, hoʻomaikaʻi ka mīkini ʻoki ʻoki laser i ke ʻano hana ʻoki kuʻuna, hoʻomaikaʻi i ka nui o ka hana pono no ka ʻoihana huahana, e like me ka lole, textile, carpet, lāʻau, acrylic, hoʻolaha, metala, kaʻa, nā lako 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
