Beam Profilers for large beams
Related subgroups: IOO, MIF, VAC
Contents
Scope
- The Beam Profilers for large beams is to be used to check the beam mode (power spacial distribution) during the commissioning phase of the intereferometer.
Current Status
General Description
- The mode matching is one of the important step to operate an optical cavity, and thus a beam profiler can help the commissioning phase.
- For KAGRA, the beam size will become about 100 mm diameter.
- There seems no commercial products that is able to measure such a large beam size so far, and we will develop such a tool.
Functions
- Measuring a spatial distribution of intensities of a laser beam for 300 mm diameter.
- Visualizing the measured data on site and remote in real time (live view).
- Offering any other functions that are usually equipped in commercial beam profilers. (Fit-function of the measured data with Gaussian profile, Functions of statistical processing, Functions of exporting the measured data)
Locations
- Anywhere in the initial alignment phase.
