Gas laserdiagram

There can be a substantial number of rotational–vibrational lines on which such a laser can be operated (→ vibronic lasers), but single-line emission and even single-frequency operation is not difficult to achieve with an intracavity bandpass filter, since the Doppler broadening of the laser transition is quite weak. If the pressure is relatively high, however, the different lines may overlap due to pressure broadening, resulting in a larger gain bandwidth.

Molecular lasers are gas lasers where the laser-active constituents are molecules rather than separate atoms or ions. Examples of such molecules are CO2 (carbon dioxide), CO (carbon monoxide), N2 (nitrogen), HF (hydrogen fluoride), DF (deuterium fluoride), NH3 (ammonia) and CH3OH (methanol). One exploits excited states of such molecules which can involve not only a purely electronic excitation (as of atoms or ions) but also vibrations and rotations of the molecules. The excitation energies are in most cases relatively small, leading to laser emission with long wavelengths in the mid or far infrared spectral region.

Indeed, nitrogen lasers may be built without any resonator mirror, or with just a mirror on one end. You may then call it an ASE source. A laser would normally be expected to have a laser resonator, but being a bit more lax, one may apply that term also to that nitrogen device.
