A new configuration of laser diode side-pumped solid-state laser is put forward. The pumping configuration divides the pumping beam of one laser diode bar into four equal portions and produces a symmetric pumping the laser medium. A ray trace simulation of the pumping beam absorption in the rod medium is made, and the effect of the absorption coefficient and laser rod diameter on the uniformity of the absorbed pumping energy distribution and the energy absorption ratio is got. An optimization of proper parameters also is made. The configuration is simple, it is very easy to obtain high beam quality output laser beam with it. A novel laser head is made with this configuration, and the initial experimental results are fairly good, which show the feasibility of this configuration.
