    Pump and cooling scheme play an essential role in getting high bright and high-average-power output for diode pumped solid-state lasers besides the temperature distribution and thermal lens effects. Base on heat conduction equations, under the condition of conductively cooling and the same pump power, temperature and thermal-induced stress and temperature induced refractive index are analyzed in detail in one-side pump zigzag slab, one-side pump diffusion bonding zigzag slab, partially pumped slab configurations. Using ray tracing method, the OPD (optical path difference) is compared in zigzag and perpendicular zigzag plane, and the thermal lens effect is analyzed with the OPD curves. The end temperature, end deformation, end OPD are also analyzed in contrast. It is shown that the beams are diverging in zigzag plane while they are focusing in perpendicular zigzag plane, and the diffusion bonding slab can eliminate end effect in evidence. At last, the compensation method of the thermal-lens effect is also proposed.
