Abstract
Coherent beam addition is an important means for achieving high power densities from semiconductor laser sources while alleviating the problems of catastrophic facet damage and of heat removal from packed arrays. Binary optics offers a versatile means of diffractively controlling and correcting optical wavefronts and can be effectively used for summing laser arrays using a variety of external cavity configurations. The authors briefly review different techniques of beam summation, including the use of binary optic microlenses, binary-phase grating couplers, the amplitude-to-phase conversion method, diffractive coupling using the Talbot effect, and the coupled microcavity with hybrid reflective/diffractive binary optical elements.
