We present a computer simulation and an experimental demonstration of the formation of Bravais lattices by multiple laser beams. It is shown that most of the Bravais lattices can be created by four or six laser beams. The body centered, the hexagonal close-packed, and the face centered structures have been specially demonstrated by using a He-Ne laser. The measured lattice constants are coincident well with the calculated values. This study will be helpful to the realization of photonic crystul in visible and infrared region.
