Kodi laser ndi chiyani?

Mwachidule, laser ndiye kuwala kopangidwa ndi chisangalalo cha zinthu. Ndipo titha kugwira ntchito zambiri ndi mtengo wa laser.

Mu Wikipedia, A laserndi chipangizo chomwe chimatulutsa kuwala kudzera munjira yokulitsa kuwala kutengera kutulutsa kwamphamvu kwa ma radiation a electromagnetic. Mawu oti "laser" ndi chidule cha "kukulitsa kuwala ndi kutulutsidwa kwa radiation". Laser yoyamba inamangidwa mu 1960 ndi Theodore H. Maiman ku Hughes Research Laboratories, pogwiritsa ntchito zolemba za Charles Hard Townes ndi Arthur Leonard Schawlow.

Laser imasiyana ndi magwero ena a kuwala chifukwa imatulutsa kuwala komwe kumagwirizana. Kugwirizana kwa malo kumalola kuti laser ikhale yolunjika pamalo olimba, ndikupangitsa kuti ntchito monga laser kudula ndi lithography. Kugwirizana kwa malo kumathandizanso kuti mtengo wa laser ukhale wopapatiza pamtunda wautali (kugundana), ndikupangitsa ntchito monga zolozera za laser ndi lidar. Ma laser amathanso kukhala ndi kulumikizana kwakanthawi kochepa, komwe kumawalola kutulutsa kuwala ndi mawonekedwe opapatiza kwambiri. Kapenanso, kulumikizana kwakanthawi kumatha kugwiritsidwa ntchito kupanga ma ultrashort pulses a kuwala kokhala ndi sipekitiramu yotakata koma nthawi yayitali ngati femtosecond.

Ma lasers amagwiritsidwa ntchito pama drive opangira ma disc, osindikiza a laser, barcode scanners, DNA sequencing zida, fiber-optic, semiconducting chip kupanga (photolithography), ndi kulumikizana kwaulele kwapang'onopang'ono, opaleshoni ya laser, ndi mankhwala akhungu, kudula ndi kuwotcherera, zida zankhondo ndi zamalamulo polemba mipherezero ndi kuyeza kuwala ndi liwiro la laser pa zosangalatsa.

Pambuyo pa chitukuko chaumisiri wakale wa laser, laser angagwiritsidwe ntchito mu ntchito zosiyanasiyana makampani, ndi imodzi mwa ntchito kusintha kwambiri ngati kwa kudula makampani, palibe zitsulo makampani zitsulo kapena sanali zitsulo, laser kudula makina kusintha mwambo kudula njira, bwino zambiri kupanga dzuwa kwa makampani zokolola, monga chovala, nsalu, pamphasa, nkhuni, akiliriki, malonda, zitsulo, galimoto, olimba zida ndi mipando mipando.

Laser idakhala imodzi mwazida zabwino kwambiri zodulira chifukwa cha mawonekedwe ake olondola kwambiri komanso othamanga kwambiri.
