The “TICKLE” submenu

Tickle is the term used for small pulses which are fed to the laser to keep the plasma
inside energized. This allows the laser to respond quickly and strongly for high speed
cutting and engraving. As the laser tube ages it may become necessary to change
these settings to maintain peak performance.
Tickle keeps the laser "warmed up" at times when the laser system is powered ON but
not firing and the top and front doors are closed. We suggest keeping the doors closed
at all times when the laser system is powered ON as this keeps the laser warmed up. If
the door(s) are open, the power to the laser tube itself is turned OFF and the tube will
cool down. The laser runs best after being warmed up for a couple of minutes.
Optimally, we can adjust the Tickle to maintain the plasma excitation level at a
threshold so that upon demand, the laser will fire instantaneously upon request from
the computer, and at greater average power levels. Having Tickle can actually extend
the life of the laser tube between gas re-charges.
Since every laser has its own personality, Tickle is adjustable through the control panel
on the laser system. Tickle is set for each individual laser at the factory, but from time
to time, the Tickle setting may need to be adjusted as the internal characteristics of the
