Many lasers can produce light only at certain optical wavelengths, or more precisely within quite narrow wavelength regions (spectral lines). Those are determined by the utilized laser transitions of the laser gain medium, which often have a narrow bandwidth of e.g. below 1 nm. The optical spectrum of such a laser source is necessarily a “line”, i.e., it exhibits a significant power spectral density only within a very narrow wavelength region.

The following table, sorted by wavelength, contains common lines mostly from solid-state lasers and gas lasers. Also, some frequently used wavelengths from sources with frequency doubling, frequency tripling or frequency quadrupling are listed.

The linewidth (optical bandwidth) of the laser light is sometimes similar to the bandwidth of the used laser transition, but in many cases it is even smaller by orders of magnitude. In particular, single-frequency lasers usually have a very narrow emission linewidth, often in the region of some kilohertz, in extreme cases even well below 1 Hz. See the article on narrow-linewidth lasers for more details.

A diffraction grating is an optical element, which separates (disperses) polychromatic light into its constituent wavelengths (colors).

For example, Nd:YAG lasers would usually operate at 1064 nm, the by far strongest line, but lasing is also possible at 946 nm, 1123 nm and 1338 nm, for example.

Various lasers with broadband gain media (e.g. Ti:sapphire) are not listed because they are not limited to certain laser lines.

Many laser gain media have multiple laser lines. In most cases, lasing occurs only on one of those: the one which first reaches the laser threshold. Which line is selected depends not only on the laser gain at that wavelength, but also on the resonator losses. One can often obtain lasing at “weaker” lines when suppressing laser action at other lines, e.g. by using at least one resonator mirror which has a low reflectivity (high transmissivity) at the unwanted wavelengths.

Various kinds of optical components have been developed for use with specific laser lines. This has led to the term laser line optics, or more specifically to terms like laser line mirrors, laser line polarizers, etc.
