A nitrogen laser is a gas laser operating in the ultraviolet range (typically 337.1 nm) using molecular nitrogen as its gain medium, pumped by an electrical discharge. The wall-plug efficiency of the nitrogen laser is low, typically 0.1% or less, though nitrogen lasers with efficiency of up to 3% have been reported in the literature. The wall-plug efficiency is the product of the following three efficiencies:

rdfs:comment	Laser azotowy - laser gazowy, którego ośrodkiem czynnym jest azot. Jest to laser trójpoziomowy, czyli górny poziom laserowy jest bezpośrednio pompowany. Laser azotowy najsilniej emituje w ultrafiolecie dla długości fali 337,1 nm i pracuje wyłącznie w trybie impulsowym. Sprawność laserów azotowych jest stosunkowo niska, najczęściej wynosi ona około 0,1%. W literaturze można znaleźć kilka przypadków mówiących o laserach azotowych osiągających do 3% sprawności. (pl) Dusíkový laser je plynový laser, který může generovat ultrafialové, viditelné i infračervené záření. Nejvíce se využívá pro generaci ultrafialového záření s vlnovou délkou 337 nm. Laser pracuje v pulzním režimu (s délkou impulzů několik ns). Doba života molekuly dusíku na spodní laserové hladině je větší, než doba života na dolní hladině molekuly. Při laserové činnosti proto dochází k rychlému nasycení přechodu a zániku inverze populace hladin. Proto buzení musí být rychlé – provádí se příčným elektrickým výbojem. Dosahované zesílení je velké. Tento laser může pracovat bez optického rezonátoru v režimu zesílené spontánní emise. (cs) Der Stickstofflaser ist ein 3-Niveau Gaslaser, der nur im Pulsbetrieb arbeiten kann. Die Anregung des Stickstoffgases erfolgt durch eine Hochspannungsentladung quer zur Ausbreitungsrichtung des Laserstrahls. Bemerkenswert am Stickstofflaser ist sein einfacher Aufbau ohne Laserresonator („Superstrahler“) und der mögliche Betrieb mit atmosphärischer Luft, sodass er mit einfachen Mitteln auch von Hobbybastlern gebaut werden kann.
