Abstract: A field mapping optical system and method for converting a light beam having a known spatially coherent first optical field to a second optical field with a required intensity distribution and flat wavefront at a desired distance from the system, by creating an intermediate optical field, between the first and second optical fields, the intermediate optical field being derived from the inverse Fourier transform of the second optical field. The optical system provides a compact and simplified field mapper.

Abstract: A process for the manufacture of custom freeform optical elements utilising parameterized modelling. A system for the automatic manufacture of a custom optical element is also described with the manufacturing being by laser micro-machining. The process and system allow customers to specify and order via a web interface and so reduce engineering time, overhead and cost.

Abstract: A diode-pumped solid state laser system and a method of diode-pumping a solid state laser in which the emitter beamlets in the diode bar are directed at a beam transformation optical element which includes a continuous twisted surface to produce a uniform and symmetrised beam in the fast field which is then focused to match an input pump area of the gain medium of the solid state laser. Embodiments to square and rectangular flat-top intensity distributions are described using a Fourier lens and a set of cylindrical orthogonal lenses.

Abstract: An optical beam shaping element to perform beam shaping of multi-mode laser beams where a uniform ring-shaped intensity distribution is produced at a focal length of a focusing lens. The optical beam shaping element with a surface having radial arms which are twisted to be curved in comparison to a known Siemens star beam shaper giving a spiral configuration. Embodiments are described in which each of the arms in the spiral structure is additionally modified with radially varied slope and/or curvature to optimise far field distribution. Relative rotation between two optical beam shaping elements forms an adjustable trident to vary power between the ring and a centre spot. The optical beam shaping element finds application in laser material processing were the spiral curvature removes hotspots and can be configured to improve through focus performance and input sensitivity.
