✦ Synopsis

A new method for infrared laser beam diagnostics was
developed based on the interferometrical measurement of the
deflection mirror deformation. It is shown that with this method
the basic beam data as beam diameter, position, intensity and
within limits also intensity distribution can be determined with a
response time of less than 200 ms. The beam analysis method is
capable to monitor high power carbon dioxide laser beams in pulsed
and cw mode.
