Laser radiation in the infrared is often generated with gas lasers. For infrared lasers, it is primarily the radiation of molecular gases that is used. With radiation transitions between Rotation Levels of a molecule whose vibrational state remains unchanged, relatively small energy differences occur. The corresponding wavelength range is between 25 μm and 1 mm. In this context, one speaks of far-infrared lasers (Section 6.1). The energy differences between Vibration Rotation Levels of the same electronic state are greater. Therefore, the wavelength of such laser radiation is smaller; it is between 5 μm and 30 μm (Section 6.2). CO is particularly widespread2-Laser that emits a wavelength of 10 μm. Find laser transitions between different ones electronic levels instead, the wavelengths are in the visible and ultraviolet range. The nitrogen and excimer lasers are particularly important (Section 7).
