Caution
The compatible laser diodes used with the CC-S can deliver up to several Watts
of coherent LASER radiation. Always wear protective goggles and observe the
safety instructions provided by the laser diode supplier when using the CC-S
driver with your laser diode.

WARNING
Handle the fiber-optics cable with care as it is fragile. Do not bend or pinch
it.
WARNING
Any software settings or hardware tinkering that is not described in this user
manual or in the usage recommendation may put the user or its environment at
risk.
WARNING
the maintenance and servicing of the CC-S should not be executed by the end
user : only AERODIODE is able to maintain the CC-S.
Safety Instructions
Wiring
Caution
- Please first connect the input pins to the board and then plug the DC Power Supply.
- Use caution when connecting the Power Supply.
- Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the CC-S module.
- Connect the ground completely. Electric shock may occur if the ground is not connected correctly.
Operating Environment
Caution
- Do not install near any heat sources such as radiators, heat registers, stoves, or other equipment (including amplifiers) that produce heat.
- To reduce the risk of fire or electric shock, do not expose the CC-S to rain or moisture.
WARNING
Not following the safety recommendations and the caution mentioned above can
lead to eye damage.
Contact
If you have any question about the CC-S module, please contact AERODIODE.

Laser diode Installation
The CC-S CW driver is dedicated to drive type 1 butterfly laser diodes (14 pins, see pin allocation below) with internal monitoring photodiode and thermoelectric cooler. The laser diode output fiber must go above the CC-S CW package.
Note
Use a torque screwdriver for the diode and please refer to the maximum allowed
torque given in the diode specification (usually around 15 to 18cNm).
Getting started
The CC-S CW USB specific cable should be unplugged during the installation.
Double-click on setup.exe to run the installer. The control software will be
installed, as well as the driver for the USB cable. A computer restart may be
required to complete the installation.
- When the software is installed, plug the USB cable into a USB port of your computer.
- Next, plug the 3,5 mm jack into the USB input female jack of the CC-S CW.
- Plug-in the CC-S CW power supply to turn on the CC-S CW laser diode driver
Click on the item “ALPhANOV Control Software” located in the Start Menu to run the CC-S CW control software
A window will appear:
Click on Connect to start the CC-S CW hardware detection. The software will
automatically detect any USB-connected CC-S CW.
The window is divided in four parts:
- The maximum current is settable in the Maximum level part. This parameter must be correctly chosen in accordance to the laser diode specifications and maximum ratings.
- Triggers in the Control part are used to select the operating mode
- The DC parameter is used to configure the DC current (internal current source mode)
- The Temperature numeric box is used to set the laser diode temperature
- The Interlock status is ON (green) when the interlock jumper is plugged
The product serial number is written on the top left of the window. The line number (address) is on the top right.
Setting the current limit
The CC-S CW laser diode driver includes a hardware overcurrent protection which requires to be set up before driving the laser diode.
Before plugging your laser diode into the CC-S CW socket, please configure this value to the maximum value recommended by the laser diode supplier. By default, this value is set to zero so the driver will not supply current. You have to change this value for enabling the driver output.
Operating modes
Current source
This two positions switch controls the current source.
External source
(BNC or manual knob)
Internal source (software)
DC current
This item rules the continuous current flowing through the laser diode.
DC current
This item sets the DC current amplitude
Temperature
This item configures the internal temperature of the laser diode (on the range 10°C / 50°C)
Laser enable

Load parameters
Click on this item to load a .csv file which contains the operating parameters. -
Save parameters
Click on this item to save the current parameters into a .csv file. This file can be loaded using the “Load parameters” menu item. -
Exit
Close the window. A confirmation is asked before shutting down the software: the laser state can be either active or inactive after the software is stopped.

Config > General Config
Restricted access to internal configuration parameters. Please use only this when asked by ALPhANOV. -
Config > Save Click on this menu item to save the current operating parameters into the CC-S CW internal memory. These parameters will be saved as default parameters in the flash memory and will be retrieved by the driver at the next power on (even if the CC-S CW driver is not connected to the PC).
Please note that if the laser state is active and parameters saved into memory, the lasing will be effective after a shutdown. -

Supported laser diodes
Type 1 Butterfly laser : standard CCS
Standard CCS are well adapted for Type 1 Butterfly laser diodes :
Type 2 Butterfly laser : CCS-Type2 (“Type 2” sticker on top of the product)
Type-2 and Type-2 Bias-T laser diode are compatible with the CCS – Type 2. Standard two pinouts of type-2 with floating anode are shown below.
Type 2 laser diodes require the CCS “Type-2” version :
Type 2 with Bias-T laser diodes require the CCS “Type-2” version :
If the anode of type-2 laser (pin 11 or/and 13) is connected to the case (ground) (pin 8 or/and 9) the type-2 diode is called “anode grounded”. As the product is intended for use with positive driven current, the current will go directly to the ground without going through the cathode of the laser diode. In this case, the user should mechanically isolated the laser diode by using furnished resin screws (M2,5 screws) and a thermal pad (electrical insulator) between the diode case and the base plate.
