Beam Profiler for large beams

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 the usual beam profiler...

Locations

Anywhere in the initial alignment phase.

Requirements

TBD

Characteristics

TBD. The larger ones and middle one should be newly developed. There are some commercial products for smaller ones.

Inspection plans

TBD

Procurement process and plans

TBD
