Beam shaping using Gaussian beam modes.
نویسندگان
چکیده
A beam shaping method is presented where a diffractive optical element (DOE) is designed by optimizing the complex mode coefficient weights of a set of Gaussian beam modes. This method is compared with the more standard unidirectional approach. Differential evolution is used for the optimization in both the unidirectional and Gaussian beam mode optimization methods. For the particular transforms carried out, the Gaussian beam mode set optimization (GBMSO) approach achieved more optimal solutions. The GBMSO approach is extended to design DOEs that control the amplitude distribution of a beam at multiple planes, rather than at just a single plane (i.e., the far field).

متن کاملTuneable Gaussian to flat-top resonator by amplitude beam shaping.
We outline a simple laser cavity comprising an opaque ring and a circular aperture that is capable of producing spatially tuneable laser modes, from a Gaussian beam to a Flat-top beam. The tuneability is achieved by varying the diameter of the aperture and thus requires no realignment of the cavity. We demonstrate this principle using a digital laser with an intra-cavity spatial light modulator...

متن کاملBeam Shaping for Phase Singularities
In this paper we are molding the phase profile of a Gaussian beam in order to achieve a phase singularity called optical vortex. For this purpose, we apply the beam shaping technique for a 635 nm wavelength radiation using a diffractive optical element with high diffractive efficiency. We use reflective spiral phase plates and fork-like computer generated holograms, fabricated with photolithogr...
