A new method that allows simultaneous frequency doubling and dynamic shaping of a Gaussian beam into a variety of light patterns is introduced. The novel technique is based on the controllable generation of multiple-vortex patterns in seeded schemes. Applications include the generation of dynamic patterns of frequency-doubled, coherent optical tweezers.
