22 Laser settings
The setting range of the laser pulse cycle varies depending on the specified value of the
pulse duration. If you change the pulse duration, adjust the laser pulse cycle.
• “Pulse cycle [μs]” (LP-RF, LP-RV):
Specify the time from beginning of one pulse to the next pulse.
A longer pulse cycle and a high scan speed will generate a dotted line.
‒ LP-RF: If you specify a long pulse cycle, the pulse energy increases. A short pulse
cycle setting results in a low pulse energy.
Setting range: 5.0 to 50.0μs
‒ LP-RV: The setting range and optimal value of the pulse cycle depends on the value
of the pulse duration.

The optimal value of the pulse cycle yields the largest average laser power and the
largest pulse energy at the selected pulse duration.
If you specify a pulse cycle that is longer than the optimal value, the average laser
power decreases. A pulse cycle setting that is shorter than the optimal value results
in a lower pulse energy.
