Quantum Composers System and Channel Modes User Manual

In the second example where the system is set to burst and the channel is set to normal the output set of
pulses will occur once but this time the system run indicator will stop flashing. To re-enable the output for a
second set of pulses the run/stop button must be pressed a second time. Once the second set of pulses is
complete the system output will shut off again.
An application where this type of control is useful is the operation of a flash lamp pumped laser. With the
system set to continuous, one channel can be set to normal (to control the flash lamp) and a second channel can
be set to single shot (Q-switch control). The system period would be set to the desired frequency rate for the
laser and the single shot channel will control the actual output of the laser. This allows the laser flash lamp to
continue to run without actually firing the laser output. Independent channel delays can also be modified to
optimize the laser’s output performance.
When using channel modes it’s important to note which modes will occur once and which ones will operate in a
continuous fashion. The single shot mode and burst mode will occur once and the system will need to be re-
armed (FUNC followed by RUN/STOP) before a second output can occur. The channel normal mode and duty-
cycle modes will run continuously once the RUN/STOP button is pressed.
Only one channel mode can be set per output but all of the outputs are independent of one another so multiple
channel modes can be set on one instrument. The channel independence and two stage modes allows for a large
variety of outputs on a single unit.
Duel system and channel modes are just one of many unique and powerful features that the Quantum
Composers pulse generators have to offer. If there are any questions about how any of our units operate or if
