12.2 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 a high measuring accuracy the shortest possible
rise time has to be set.
