The concept of a laser level has been around since at least the early 1970s, [2] the original spinning-mirror design laser plane and line level was patented by the late 1980s, [3] and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s. It was invented by Oscar Soliz in the late ...
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...

A ruby laser most often consists of a ruby rod that must be pumped with very high energy, usually from a flashtube, to achieve a population inversion.The rod is often placed between two mirrors, forming an optical cavity, which oscillate the light produced by the ruby's fluorescence, causing stimulated emission.
