Coherent combination of laser arrays is an effective way to achieve high-brightness laser beam. Mutual injection phase locking is a passive way of coherent combination. Theoretical analysis and simulation of the coherent properties of the corner cube are done. The scheme to coherently combine beams from pulsed solid state lasers with corner cube cavity is proposed. The experiments to coherently combine two and six beams from pulsed solid state lasers are performed. The output energy is more than 255 mJ with the power combination efficiency of approximately 80% and visibility of about 0.5. The simple structure is efficient to achieve coherent combination of laser beams.
