9.9.3 

Measure beam pointing stability

DANGER

Serious eye or skin injury due to laser radiation

Observe the warning messages in chapter 9.1 on page 44.

Starting measurement

1.  Switch on the laser.

2.  Enter z-position.

3.  Click the 

Start

 button.

 

The measurement begins. 

 During the measurement, the prog-

ress is shown in the following indica-

tors:

Pre-caustic

While the indicator is rotating, the z1 and 

z2 positions along the beam propagation 

are identified. The positions are optimized 

according to Primes quality criteria.

After successful pre-caustic 

measurement, the indicator lights up 

green.

 The process is visualized in the 

False-

color Image

 tool. 

Measuring beam pointing

While the indicator is rotating, the beam 

center and the angle are constantly deter-

mined.

 The determined measuring points 

are displayed in the coordinates of 

the 

Beam Pointing Stability

 tool. 

The current position of the beam is 

marked with a large X, previous posi-

tions are marked with a small x.
