To investigate the influence of heat loads in laser crystals on laser beam quality, we employed several Nd-doped laser crystals as gain media.Experimental results revealed that the best beam quality was generated by using the diffusion-bonded composite cr ystal. However, the fundamental laser beam was seriously distorted when a 3-mm-thick, 1-at.% Nd:YVO4 crystal was used. The study has demonstrated that the thermal conductivity was proved to be a key point to generate an excellent TEM00 laser beam.
