In this paper, the Gaussian, Lorentz and Lorentz-Gaussian beams are introduced and the effects of these beams as the pump profile on the absorption efficiency of the diode-side-pumped solid state lasers are investigated. We illustrate that the absorption efficiency for Lorentz-Gaussian profile is higher than the two others. We have also shown that for entrance Lorentz-Gaussian profile, the absorption efficiency is increasing with decreasing the distance from the diodes to the slits and increasing the diameter of the laser rod.
