Page 4: Introduction
1 Introduction The Quantum Composers Laser Diode Driver Controller (LDDC) and Laser System Controller (LSC) provide a means of controlling various types of laser diode driver supplies. It allows the ability to easily control current levels, pulse modes, and interlock controls as well as monitor voltage and current levels from the driver. -
Page 5: Driver Connection
Driver I/O connector pins 13 and 14, it is required that the current be limited to less than 8A by means of fusing it at 5A. If an external power supply is chosen to be used, it is recommended that the mains outlet be easily accessible so that the plug of the external power supply can be easily removed. - Page 6 5. A message window will launch asking if you want to continue installing this driver. Select the “Continue Anyway” button. 6. It should now indicate the it is installing a driver for a “LDDC USB Communications Port”. 7. A message should then indicate that the drivers have been successfully installed. 8.

Page 7: User Controls
3 User Controls Figure 3 (User Controls) The main user controls consist of: • Enable/Disable. This button is used to initially enable the driver. On supplies that have both an enable and a pulse control signal, this will activate the enable signal. On units that do not have pulse control, this will enable the activation of the enable control signal via the start/stop button. -
Page 8: Display/Indicators
4 Display/Indicators The following are used for user indicators and information: • A 4 line x 16 character LCD backlit display. This display will show various information depending on the active screen. • 3 indicator LEDs. An Enabled indicator (Blue) shows when the unit is in an enabled state, ready to fire or start pulsing the supply. -

Line 3: Width. This sets the pulse width (in seconds) of the triggering pulse to the driver when in pulsed, burst or single shot mode. The width adjustment will be limited to a maximum of roughly 90% of the rate period. Line 4: Count. -
Page 11: Interlock Status Information Page
• Gate Active Low. The unit will start running as long as a low level (0V) is present on at the external trigge input. Line 4: Sync Ouptut. The sync output is a TTL signal that can be synchronized to the pulse control signal, q-sw trigger or a combination of both. -
Page 12: System Setup Page #2
The first system setup page allows you to select the type of driver you have and adjust the expected compliance voltage and current ranges from the driver the LDDC/LSC is controlling. Please refer to your specific diode driver data sheet for these values. Line 1: Indication of System Setup #1 page. -

If no auxiliary power can be provided, an external +15VDC (200mA) supply may be used. Turn on the LDDC/LSC, press any key, and take note of the LDDC/LSC main screen which states what the maximum current output is set to. Ensure that this maximum current value does not exceed that of the Diode Driver or the laser diode.

get one pulse control signal for every rising (or falling) edge that the unit receives. This is the most common mode of operation. If you are in burst mode, then the burst sequence will start. If in pulsed mode, then the unit will begin pulsing once an external edge is received. If stop is selected any ongoing sequence will be stopped. -
