Chii chinonzi laser uye ndiani akaigadzira?
Context:Laser mudziyo unobudisa chiedza kupfurikidza negadziriro yokunatsiridza optical kwakavakirwa pakukurudzira kubuda kwemwaranzi yemagetsi. Izwi rokuti laser ishoko rakapfupikiswa rinoreva kuwedzera chiedza nokukurudzira kubuda kwemwaranzi. Laser yokutanga yakavakwa muna 1960 naTheodore Maiman paHughes Research Laboratories, zvichibva pabasa raCharles H. Townes naArthur Leonard Schawlow.  Laser inosiyana nemamwe manyuko echiedza pakuti inoburitsa chiedza chisingachinji. Kubatana munzvimbo kunobvumira kuti laser iratidzwe panzvimbo yakamanikana, zvichibvumira kushandiswa kwakadai sokucheka laser uye lithography. Kubatana munzvimbo kunobvumirawo mwaranzi yelaser kuti igare yakatetepa pamadaro makuru (collimation), zvichigonesa kushandiswa kwakadai semapoinzi elaser uye lidar (kucherechedza chiedza uye kureba). Lasers dzinogonawo kuva nechiito chakakwirira chenguva, icho chinodzibvumira kubudisa chiedza nechiedza chiduku zvikuru. Neimwe nzira, kupindirana kwenguva kunogona kushandiswa kugadzira kupisa kupfupi kwechiedza nehupamhi hwakawanda asi nguva pfupi seye femtosecond.  Lasers anoshandiswa mune Optical Disc Zvifambiso, Laser vaidhinda, Barcode scanners, DNA sequencing zviridzwa, faibha-optic, uye vakasununguka-nzvimbo Optical kukurukurirana, semiconductor Chip kugadzira (photolithography), Laser kuvhiya uye ganda kurapwa, kucheka uye nomoto zvinhu, vemauto uye mutemo masimba zvokushandisa chiratidzo zvinangwa uye kuyera siyana uye nokukurumidza, uye Laser chiedza anoratidza kuti varaidzo. Semiconductor lasers mubhuruu kusvika pedyo neUV yakashandiswawo panzvimbo yechiedza-chinobudisa diodes (LEDs) kufadza fluorescence sechiedza chena. Ikoku kunobvumira nzvimbo duku zvikuru inobudisa nemhaka yechiedza chikuru zvikuru chelaser uye kunodzivisa kuderera kunotambudzwa neLEDs; zvishandiso zvakadaro zvinoshandiswa kare mumamwe marambi makuru emotokari.
Laser mudziyo unobudisa chiedza chinobva kunobva mwaranzi yemagetsi. Laser yokutanga yakavakwa muna 1960 naTheodore Maiman paHughes Research Laboratories, yakavakirwa pabasa rokurangarira raCharles H. Townes naArthur Leonard Schawlow.  Laser dzinobudisa rudzi rwakati rwechiedza. Chiedza chinopindirana. Kubatana kunogona kuyerwa munzvimbo kana kuti munguva. Kubatana kwenzvimbo kunobvumira mwaranzi dzelaser kuti dzirambe dzakatetepa pamadaro makuru. Kubatana kwenguva kunogona kushandiswa kugadzira mapundu echiedza mapfupi zvikuru.  Mimwe mienzaniso yekushandiswa kwema lasers ndeye optical disc drives, laser printers, barcode scanners, fiber optics uye photolithography
