Operating the Unit
6.1
Setting the Laser System Parameters
The user can select among various operating modes (continuous-wave, single pulse, pulse
train, superpulse and scanner) and set the corresponding parameters (such as laser output
power, pulse length, scanning pattern size) in accordance with surgical needs. The selected
parameters are always indicated on the LCD. In addition, the average laser output is
automatically calculated and indicated as well. These parameters can be changed at any time
and in any sequence after the unit has been turned on. To prevent an accidental change of the
treatment/irradiation parameters while the laser beam is being used on the patient, the
system automatically blocks all buttons (rendering them inoperable) as soon as the footswitch
is operated.
6.2
Continuous-Wave Mode
In this mode, the laser works with a continuous-wave beam which emits energy continuously
at a constant output power as long as the footswitch is held down. This mode of operation –
also called "CW" mode – is available only with CO
such as the MCO25plus.

Parameters in Continuous-Wave (CW) Mode
•
Output power (average power):
Use the "SELECT" button to highlight the "POWER" field, then change the power value
using the arrow buttons (increase or decrease as required). Both buttons provide an
autorepeat function: keeping the respective button pressed continuously increases or
decreases the power value increment by increment. The selected value is indicated on the
LCD.
Adjustment range:
6.3
Single-Pulse Mode
This mode allows the application of single pulses whose intensity and duration can be defined
by the user. Upon operating the footswitch and holding it down, the laser emission process will
be interrupted as soon as the selected pulse time has elapsed (in other words, only one pulse
is emitted). If the footswitch is released before the selected pulse time has elapsed, the laser
beam is cut off immediately.
Attention!
For safety reasons, the footswitch function has absolute priority. So as soon as the
footswitch is released, the laser beam will be cut off, irrespective of the set pulse
time.
