7.4.3 CO
2
Mode
The command
set_laser_mode(0)
selects the CO
2
laser mode (laser mode 0). The laser control timing
diagram
shows the corresponding signals.
For “laser active” operation (if applicable after a
LaserOn delay and if enabled via
or
)
• The LASERON signal is switched on and
• Two alternating modulation signals are provided
at the LASER1 and LASER2 outputs with pulse
lengths and periods that can be defined via
or
For “laser standby” operation (if applicable after a
LaserOff delay)
• The LASERON signal is switched off and
• Alternating standby pulses are provided at the
LASER1 and LASER2 outputs with pulse lengths
and periods that can be defined via
