Notes
• LASER1 signals and LASER2 signals are
– activated by: HalfPeriod

PulseLength
0
– deactivated by: HalfPeriod = 0 and/or
PulseLength = 0 (default setting after
load_program_file)
• The LASER2 signal is phase-shifted by half a signal
period in relation to the LASER1 signal. It can be
used for the control of a second laser tube. By
set_laser_control (Bit #1
be exchanged with each other. To control laser
power, the pulse length of the LASER1 and
LASER2 signals can be varied. Both signals share
the same pulse lengths and periods.
• For the LASER1 signals and LASER2 signals, half
of the output period must be specified.
• set_laser_pulses and set_laser_timing
delayed short list commands. They can also be
used to change the laser parameters between
two Mark Commands.
The time base for the signals is always:
– 1/64 µs in RTC6 Standard

page 168
– 1/8 µs in RTC4 Compatibility
