22.2.1
Measuring configuration selection
There are various measuring options to differentiate between:
• Measuring a single plane or a complete caustic
• Measuring a complete pulse or just a single section
• Measuring with a fixed integration time or with integration time control
• Measuring with triggered or untriggered operation
• Variations of optimal integration time caused by changing the attenuation
If you combine these measuring options with the pulse parameters:
• Pulse duration: fs – ms
• Pulse frequency: 1 Hz – 1 kHz
There are several options. The following merely describes a rough structure that is intended to help in choos-
ing measuring settings.
22.2.2
Influence of the pulse parameters on the integration time control
The software-operated integration time control always assumes that there is a continual laser beam.
This may cause quantization of the integration time for slow pulse lasers (< 500 Hz) or lasers with high pulse
energy (integration time very short). Tab. 22.1 on page 91 And the diagram in Fig. 3.1 on page 12
makes this clear.
