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

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.
