A new concept of laser resonator, which uses two binary transmittance filters in two conjugated Fourier planes, can synthesize various optical waves. We have implemented this method on a Nd:YAG oscillator and produced high-energy (>200-mJ) short-duration pulses with uniform amplitude and spatial phase distribution on a circular cross section.
