We discuss an efficient, side-pumped Nd:YVO4 slab laser using two 20 W diode laser bars with a CW output power greater than 15 W, a slope efficiency of 51.6% and an overall efficiency of 40%. In Q-switched operation, over 11 W of output power was achieved at a repetition rate of 50 kHz in a single transverse mode, near-diffraction limited beam with pulse widths less than 12 ns.
