Menene laser kuma wanene ya ƙirƙira shi?
Context:Laser na'ura ce da ke fitar da haske ta hanyar aiwatar da fadada gani wanda ya danganci fitowar fitowar hasken lantarki. Kalmar laser wani abu ne wanda ya samo asali ne a matsayin acronym don fadada haske ta hanyar motsawar radiation. An gina laser na farko a 1960 da Theodore Maiman a Hughes Research Laboratories, bisa ga aikin da Charles H. Townes da Arthur Leonard Schawlow suka yi.  Laser ya bambanta da sauran tushen haske a yadda yake fitar da haske da ke da daidaito. Haɗin sararin samaniya yana ba da damar mayar da hankali ga laser zuwa wani wuri mai mahimmanci, yana ba da damar aikace-aikace kamar yankan laser da lithography. Haɗin sararin samaniya kuma yana ba da damar hasken laser ya kasance mai ƙanƙanta a kan manyan nesa (collimation), yana ba da damar aikace-aikace kamar alamun laser da lidar (ganewar haske da kewayawa). Lasers kuma na iya samun babban haɗin lokaci, wanda ke ba su damar fitar da haske tare da kunkuntar bakan. A madadin haka, ana iya amfani da daidaiton lokaci don samar da ƙananan ƙarancin haske tare da faɗakarwa mai yawa amma tsawon lokaci kamar femtosecond.  Ana amfani da lasers a cikin na'urorin faifai na gani, firintocin laser, masu binciken barcode, kayan aikin DNA, fiber-optic, da kuma sadarwar sararin samaniya, samar da kwakwalwan kwakwalwa (photolithography), tiyata da laser da kuma maganin fata, yankan da walda kayan aiki, sojoji da na'urorin tilasta yin doka don yin alama da kuma auna nesa da sauri, da kuma a cikin nuni na hasken laser don nishaɗi. An kuma yi amfani da lasers na semiconductor a cikin shuɗi zuwa kusa da UV a madadin diodes masu ba da haske (LEDs) don motsawa fluorescence a matsayin tushen haske mai haske. Wannan yana ba da izinin ƙaramin yanki mai watsawa saboda mafi girman hasken laser kuma yana guje wa faɗuwar da LEDs ke sha wahala; irin waɗannan na'urori an riga an yi amfani da su a wasu fitilun mota.
Laser na'ura ce da ke fitar da haske daga tushen radiation na lantarki. An gina laser na farko a 1960 ta Theodore Maiman a Hughes Research Laboratories, bisa ga aikin da Charles H. Townes da Arthur Leonard Schawlow suka yi.  Lasers suna fitar da wani nau'in haske. Haske wanda yake da daidaito. Ana iya auna daidaito a sararin samaniya ko na lokaci. Haɗin sararin samaniya yana ba da damar hasken laser ya kasance kunkuntar a kan nesa mai nisa. Za'a iya amfani da daidaito na lokaci don samar da ƙananan ƙarancin haske.  Wasu misalai na amfani da lasers sune na'urorin faifai na gani, firintocin laser, na'urorin binciken barcode, fiber optics da photolithography
