VLASE™ IR
At the end of the thermalization phase, before starting another marking phase, the FPK
(First Pulse Killing) procedure needs to be implemented in order to discharge the crys-
tal, thus avoiding the generation of "giant" pulses which may cause marking defects as
well as damages to the internal optics of the resonator.
To discharge the crystal, the Q-Switch is kept closed (Q SW MOD signal at 0 V) and the
EMISSION signal is brought to a 0V level for at least 450 µs, so as to cut off the current in
the laser diode and consequently the pumping of the crystal (FPK delay).

CAUTION
It is strongly recommended NOT to change the set FPK Shot time and delay,
because they have been optimized to ensure the safety of the marking sys-
tem and the performance marking linked to the high stability of the laser
pulses.
