File:Commercial laser lines.svg

Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. Full lines or areas mean CW emission, dotted mean pulsed emission. The height of the line gives an indication of the maximal power/pulse energy commercially available. For the Ar⁺-Kr⁺ laser only the most important lines are labeled, the many other are shown only by a short tick, independently of their power. Note that the wavelength axis is highly distorted: up to 1000 nm it is linear in the wavelength, from then on logarithmic (with 300 px per decade up to 10 µm, then 30 px per decade). This is necessary for a good presentation of the visible region. For semiconductor lasers a solid fill shows the powers achievable with a single emitter, while horizontal lines indicate bars or stacks of bars.
