Selecting the operating mode
The user can select the operating mode (continuous wave, single pulse, pulse sequence, super
pulse and scan) as well as the corresponding parameters such as laser output power, pulse
duration, size of the scan shape, as desired. The selected values will always be shown on the
LCD display. In addition, the average laser output is displayed. These parameters can be
changed any time and in any order after the device has been switched on. The keyboard is
automatically locked when the foot switch is activated during laser treatment.
6.6.1
Continuous Operation
This operating mode works with continuous laser light at continuous laser output as long as
the foot switch is activated. This mode is only available for CO
2
lasers with direct current
excitation, which is possible with the MCO 25 plus. This laser mode is often called “CW”
(continuous wave).
Parameters in Continuous Operation
Power output (average power)
•
Use the
SELECT
key to select the field
POWER
.
•
Increase or decrease the power output value using the arrow keys.
Both keys have an automatic repetition function which increases or decreases the value
repeatedly when the key is held down. The selected value is shown on the LCD display.
Setting range: 2–25 W in steps of 1 W.
6.6.2
Single Pulse Mode
NOTICE
Interruption of the laser treatment in case of inadvertent release of foot switch!
For safety reasons, the foot switch control has absolute priority. If the foot switch is released,
the laser is deactivated immediately regardless of the time setting.
The single pulse allows a one-time laser application with defined time and power. While the
foot switch is pressed, the emission of laser light is stopped after the preset time has elapsed.
If the foot switch is released prematurely during the preset single pulse time, the emission of
laser light is interrupted immediately.
