Abstract
Although conventional optics (refractive components) for laser diode collimation usually consist of several elements, their ability to correct wavefront aberrations (astigmatism, etc.) are limited. Diffractive elements in principle allow to generate any wavefront, but they show severe dispersion, diminishing the quality of a holographic Laserdiode collimator. An optical system with diffractive and refractive elements may combine the advantages of both concepts (arbitrary wavefront correction and low dispersion). Furthermore this concept helps to reduce the number of optical elements resulting in miniaturized optical systems.
