JUSIFA—A new user‐dedicated ASAXS beamline for materials science
The fully computer‐controlled user‐dedicated small‐angle scattering facility JUSIFA was set up for general use at the DORIS Synchrotron Radiation Source in DESY (Hamburg). This beamline is especially… Expand
Wave-optical structure design with the local plane-interface approximation
Abstract The design of an optical element profile with specified transmission function for a given incident wave is of fundamental concern in optical design. A well-known example is the design of an… Expand
Self-supporting thin-film beam splitter for far-infrared interferometers
Commercially available plastic films have been examined, in the spectral range up to 1200 cm−1, for use as a beam splitter in far-infrared Michelson interferometers. The materials reported include… Expand
Beam shaping of broad-area diode lasers: principles and benefits
High brightness is a major issue in most high-power diode laser applications. The brightness of a laser diode primarily depends on the optical power and the product of beam-quality factors in x- and… Expand

A wave-front-correction element (WFCE) is produced to make a cylindrical Ag-ion-exchanged gradient-index (GRIN) lens with a high numerical aperture and the power irradiated into a full angle of 2 mrad can be enhanced by a factor of 1.8 with the WFCE. Expand
