Overview of the wavelengths of commercially available lasers.
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.

Own work.The data and its references can be found in the spreadsheet Commercial laser lines.xls (unfortunately Wikipedia does not allow uploading spreadsheets). Currently most of the data is taken from Weber's book Handbook of laser wavelengths [1], with newer data in particular for semiconductor lasers. For quasi-cw lasers (e.g. metal vapor lasers) the length of the full line gives the mean power. Uses File:Linear visible spectrum.svg
