Continuous Wave Mode and Pulse Mode

The MLD-810 Laser delivers laser energy in either a Continuous Wave (CW) or
Pulse Mode ( ). Selecting the appropriate mode is important for controlling the
temperature of the target tissue as well as using an efficient amount of energy.
Continuous Wave Mode
Continuous Wave (CW) mode is
generally the fastest way to ablate
tissues. However, heat can build up
and damage the target and adjacent
tissues. Cool the tissues using
periodic blasts of air from a triplex
syringe and high speed suction. You
may want to use water to cool areas
where there is prolonged exposure to
the laser beam.
When the laser is in CW mode,
the amount of power delivered is
equal to the power setting that
has been selected.
For example, a 1.0 W power
setting in CW Mode generates an
average power output of
1.0 W.
Do not use an air syringe when you have an opening in soft tissue adjacent to
or within the surgery site. An air embolism may occur as a result of air that may be
captured within the tissue during the cooling process.
Pulse Mode
Pulse Mode serves as an alternate form of
laser energy delivery. Pulsing of the laser
energy reduces the average power emitted
and allows for some cooling of the tissue
between energy emissions.
In Pulse Mode, the MLD-810 Laser is
programmed to deliver ten pulses per
second (fixed), each with a pulse duration
of 0.05 seconds (fixed), resulting in a duty
cycle (percentage of time within each
second that the laser is emitting energy)
of 50%. Thus, when the laser is in Pulse
Mode, the average power delivered is equal
to 50% of the power setting that has been
selected (displayed on the OLED).
For example, a 2.0 W power setting in
Pulse Mode generates an average power
output of 1.0 W (equivalent to the average
power output of a 1.0 W power setting in
CW Mode).
