Duration of trigger signal has no influence on the laser operation. However, to provide minimum jitter, short fore front may require. Any interference in this channel may cause false triggering of the laser. To suppress short interference pulses a resistor of about 5 kOhm by nominal and a capacitor of 10-100 pF by nominal are installed in parallel at input of trigger signal.
