High average power solid-state laser and its propagation in the atmosphere

As a high power laser which has some important application background, the selection of solid-state laser’s parameters such as wavelength, beam aperture, power, and beam quality has been analyzed, and the influencing factors such as the atmospheric optical characteristics, the effects of laser beams propagation in the atmosphere, and the mechanism and efficiency of laser beam coupling with targets has been investigated. The related results show that the general efficiency of 100 kW solid-state lasers corresponds to DF lasers which have two to three times average out power, thus the high average out power solid-state laser is demonstrated as a laser of some potential advantages and favorable prosperity.
