Figure 7 Schematic of laser pulse duration adjustment
（
200ns
）
For example, if using Beijing JCZ Technology Co. marking card to adjust laser pulse
duration, the setting processes are described as follows:
a)
Make sure the power supply, DB25 cable, control card and computer are correctly
connected, and then turn on the 24V power supply.
b)
Open Ezcad2.7.6 (or other version), then click ‘F3’, the configuration parameter should
show up, select ‘Fiber’ in category of the ‘Laser Control’ panel, follow that select ‘IPG_YLPM’,
and then close this window.
c)
Pulse duration can be modified by the ‘Duration’ on the right side of the window. If the
setting duration is smaller than the limiting minimum value, the duration of output laser will be
2ns (minimum). If the setting duration is larger than the limiting maximum value, the duration of
output laser will be 200ns (maximum). If the setting duration within the range, the duration of
output laser will tend to the smaller side.
