Intracavity beam shaping using diffractive elements has already been successfully demonstrated in the field of solid state lasers, gas lasers and external cavity diode laser arrays. In this paper, we discuss the transition from free-space to integrated optics and report on the technological concepts to experimentally realize intracavity beam shaping in polymeric waveguide dye lasers.
