Laser parameter setting
12.2.1 Setting the laser rise time
The applicable measurement time is between 0.1 s and 2.0 s, which has to be trans-
ferred to the laser controller as pulse length. The maximum laser rise time for measuring
the power cannot exceed 100 µs. This limit has to be adhered to in order to avoid incor-
rect results of the power measurement.
Some laser beam sources are factory set with power ramps of up to a few 100 ms to
switch on the laser beam. To achieve the correct power values the shortest possible rise
time (< 100 μs) has to be set.
