Beam Profiler for large beams
Related subgroups: IOO, MIF, VAC
Contents
Scope
The scope of Beam Profiler for large beams is to check the beam mode during the phase of initial alignment of optics.
Applicable Documents
TBD
General Description
The mode matching is one of the important step to construct an optical cavity. For KAGAR, the beam size will become about 10cm diameter, while there seems no commercial products that is able to measure such a large beam size. Thus we should develop such tool.
Functions
- Measuring the spatial distribution of intensities of a laser beam.
- Fitting the intensity distribution with theoretical Gaussian profile.
- Average, Data extraction, etc, anything that are usually equipped to a usual beam profiler...
Locations
Anywhere in the initial alignment phase.

Characteristics
