A one-dimensional(1D) top-hat,diode-end-pumped,electro-optically Q-switched Nd:YVO4 slab laser is demonstrated.Under the pump power of 175.5 W,26.3-W output power is obtained with the repetition rate of 5 kHz and the pulse width of 4.3 ns.The output beam has a good top-hat beam profile in both the near field and the far field.
