4.5 THERMALIZATION AND SUPPRESSION OF GIANT PULSES
Thermalization is useful in order to obtain a good marking quality.
To obtain uniform markings and work processes it is important to keep the Nd:YVO4 crystal constantly
pumped. This operation is called thermalization and it is implemented by supplying the laser diode with a
suitable level of current. In this way a certain amount of pumping radiation at 808 nm excites the crystal, but
with the Q-switch closed, no laser radiation is emitted by the system
.
With the Vlase
TM
source, this procedure can be implemented using Software Thermalization.
Software thermalization
Software thermalization is implemented automatically by the Lighter marking software and consists in
defining, within the marking project, a certain thermalization level at which the crystal is maintained during
the non-emission intervals. It is generally recommended to keep the level of thermalization similar to the
power level used for the marking or slightly lower.
