Lasers and laser-related equipment - Test methods for laser beam parameters - Polarization
Also Known As:
ISO 12005:2022 is a standard that provides a method for determining the polarization status and degree of polarization of a laser beam. The method described in the standard is relatively quick and simple, requiring minimum equipment. It can be used for continuous wave lasers and repetitively pulsed lasers, as long as the electric field vector orientation remains constant between pulses.
The standard also specifies a method for determining the direction of the electric-field vector oscillation in the case of linearly polarized laser beams, whether they are completely or partially polarized. It assumes that the laser radiation is quasimonochromatic and sufficiently stable. The standard is applicable to laser beams that have uniform polarization over their cross-sectional area.
Knowing the polarization status of a laser beam is important for certain applications, especially when the beam needs to be coupled with polarization dependent devices, such as polarization maintaining fibers. The standard is not limited to narrow and collimated laser beams but can also be used for highly divergent beams and beams with large apertures.
