Def_SIMMER： To control the amplitude of the first pulse. The larger the value is, the higher the
first pulse will be.
[Suitable SIMMER]
Def_PRR: Under internal PRR mode, the system will output based on the default PRR if no
external frequency signal is detected.
Def_pulse: The system will output laser pulses with default pulse-width if it cannot be
controlled externally.
EXT.PRR: Tick this choice to use the external frequency mode (The final output laser pulses
will be synchronized with external frequency signal. This mode can be used when the control
card has optimized the external signal). If un-ticked, internal frequency mode will be selected
(System will firstly calculate the external frequency signaland then generate the pulse signal
internally. This mode can be used to define the default PRR of the laser when there is no external
frequency signal detected by the control card.
The default mode is external frequency mode.
