The measurement of total scatter losses is a major prerequisite for the development, optimization and commercialization of high quality optical components. Especially in laser technology, optical scattering gained of importance in the source of the d

Lasers in Material Processing.
For industrial applications of high power laser diodes it is of interest to know the focal region of the laser beam for efficient fiber coupling and material processing. Similar questions also occur with laser diodes for the optical communication ind

Reciprocal quantities are introduced in terms of the second moments associated with the near and far fields in wide- angle scalar wave propagation. Free fields are considered and conditions for the finiteness of the second moments are analyzed. Relat

Making use of the angular-spectrum representation of a radiation field a formula for the second moments is given, which applies to the propagation of non paraxial beams. The formula was originally derived by Belanger et al. [Bel94] for coherent field

The Wigner Distribution Function (WDF) has been well known in quantum mechanics since the thirties. Applied to paraxial optics it can be considered as a phase-space representation of quasi-monochromatic, partially coherent beams. For a two-dimensiona

In this paper we propose a calibration procedure that allows beam characterization based on power content (or any other reasonable) beam widths. Once the characterization is done, the beam width behind ABCD-systems can be predicted with sufficient ac

The transmission properties of different types of all-silica fibers are investigated, using a multimode high-power cw Nd:YAG rod laser with 2000 W output power. The dependence of the output upon the input beam parameters, waist diameter and divergenc
