16.3.2 Measuring configuration selection
There are various measuring options to differentiate between:
• Measuring a single plane or a caustic
• Measuring a complete pulse or just a single section
• Measuring with freely adjustable integration time or with automatic integration time control
• Measuring in trigger operation or quasi-cw operation
• Variations of optimal integration time caused by changing the attenuation
Combining these measurement options with the following pulse parameters provides numerous possibilities:
• Pulse duration: fs – ms
• Pulse frequency: 1 Hz – 1 kHz
The following merely describes a rough structure that is intended to help in choosing measuring settings.
16.3.3 Influence of the pulse parameters on the integration time control
The software-operated integration time control always assumes that there is a cw 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. 16.1 And the diagram in Fig. 16.3 on page 112 illustrates this.
