The diameter of beams of lasers is the distance between two locations in an Gaussian distribution, whose intensities are 1/e 2 times the maximum value. Not all lasers feature the same beam diameter. Certain lasers begin by forming a coherent beam, and then an injection seeder is employed to focus the laser's energies in a narrower range than is otherwise feasible. Consequently, the diameter of the class 3B laser or class 4R depends on the strength of the source.

In order to obtain the most effective intensity distribution the laser beam is placed on top of a thin pellet of fuel. The intense temperature of the beam causes the fuel to melt. This is in essence a recreation of the conditions found in deep stars. The process releases enormous amounts of energy. This technology was developed by the Lawrence Livermore National Laboratory in California. The main advantages of using a laser-based energy source The ability to store the energy generated by renewable sources.

Lasers emit light within an extremely narrow wavelength. Lasers emit light with very low frequencies, with the most prevalent center frequency is 1064 nm. The color of the laser's light is determined by the laser material. For example, a Neodymium-Yttrium-Algarnet (Nd:YAG) crystal produces a red-orange light with a wavelength of 1064 nm. CO2 lasers are also used in welding and cutting.
