ISO 13694-2015 pdf free.Optics and photonics—Lasers and laser-related equipment – Test methods for laser beam power (energy) density distribution.
ISO 13694 specifies methods by which the measurement of power lenergyl density distribution is made and defines parameters for the characterization of the spatial properties of laser power Iencrgy density distribution functions at a given plane.
The methods given in this International Standard are intended to be used for the testing and characterization of both continuous wave (cw) and I)LIlscd laser beams used in optics and optical inst ru ments.

3 Terms and definitions
For the UOSCS of this docu ment, the terms and deli nitions given in ISO 11145 and I FC 61040 and the following apply.
4 Coordinate system
The x, y, Z Cartesian axes define the orthogonal space directions in the beam axes system. The x and y axes are transverse to the beam and define the transverse plane. The beam propagates along the z axis. The origin of the z axis is in a reference xy plane defined by laser manufacturer, e.g. the front of the laser enclosure. For elliptical beams, the principal axes of the distribution coincide with the x and y axes, respectively. In cases for which the principal axes of the distribution are rotated with respect to the laboratory coordinate system, the provisions of ISO 11146 describing coordinate rotation through an azimuth angle φ into the laboratory system shall apply.ISO 13694 pdf free download.
