A small and well shaped focal spot remains the ultimate goal for a good design of a beam handling system. The thermal deformations of the mirrors used for focusing on or simply directing a laser beam cause distortions of the wavefronts which result in an increased focal spot. This circumstance reduces the peak irradiance with prejudice for the efficiency and the overall performance of the laser apparatus. In some systems the laser beam is used in stations which are separated several meters from the source. In these cases some effects due to the air turbulence and the thermal blooming can be of some relevance.
