Page 3: General Information
1. General information Please read this manual carefully, it describes the hazard the user might be exposed to while using the product. It also explains in details how to use the product in the safest and more efficient way possible. The safety of any system incorporating the product is the responsibility of the assembler of the system. -
Page 4: Safety Instructions
WARNING Avoid all chocs and strains when handling the CCM. WARNING Handle the fiber-optics 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. -

Page 8: Installation
4. Installation The CCM driver is able to drive any type of laser diode until 150W / 36 V / 21 A 4.1. Laser diode installation for efficient thermal regulation Caution Care must be taken in order to properly cool the laser diode. In case of bad thermal contacts of the diode and thermistor, the regulation may be unstable. - Page 9 Choose the one that best suits your setup, take into consideration the size of your diode, the length of the power cables of your diode and TECs. They should easily reach their respective connectors, while not being to tensed to avoid any strain on the solders. In this example, the chosen spot is the (1).
- Page 10 (B) Spread some thermal grease on the top surface of the thermoelectric cooler and then lay down the diode on top of it. Again, please take care not to introduce any thermal contact between both plates of the TEC. To optimize thermal efficiency, if the diode is small compared to the thermoelectric cooler, you can paste a piece of thermal conductive sheet (graphite for example) going from the thermoelectric cooler to the laser diode sides.

4.3. Example of multiple laser diodes and TEC connected to one CCM On the picture below, two IPG laser diodes are connected in Serial to a CCM device with only one TEC. On the front page of this manual, three BWT laser diodes are connected in serial to a CCM with three TEC (one for each laser diode) also connected in serial. -
Page 13: Mechanical Holding
4.4. Mechanical holding Screw the holding plate on top of the laser diode in order to hold the laser diode and guarantee good thermal efficiency. WARNING The Holding plates should be screwed with a torque of 15cN.m. Too much pressure may damage the TEC and too low pressure will not perform good uniform thermal contact with the TEC. -
Page 14: Getting Started
5. Getting Started 5.1. Software installation Caution The CCM USB specific cable should be unplugged during the installation. Note Please note that the USB cable can also be unplugged after the board has been configured. Double-click on setup.exe to run the installer. The control software will be installed, as well as the driver for the USB cable. - Page 15 Click on the “ALPhANOV Control Software” item located in the Start Menu in order to run the CCM control software. A window appears: Click on Connect to start the CCM hardware detection. The software automatically detects any USB-connected AeroDIODE devices.

MAX LEVELS: The maximum current and voltage values are settable in the Max levels part and must be chosen in accordance to the laser diode specifications and operating data everytime a new laser diode is mounted on the CCM module (see bellow). The floppy disk logo indicates that these values can be stored into the CCM memory (upon clicking) 2.

Page 25: Use Of Optional Tombak To Generate Full Adjustable Pulses
6.2. Use of optional TOMBAK to generate full adjustable pulses The CCM could be used with a TOMBAK product to pulsed the high power laser diode. In this case, the TOMBAK can be mounted/unmounted on the other side of the heat sink as shown below. - Page 26 The TOMBAK could then be powered up using the dedicated 5V DC power supply. The CCM could also be powered up using the 24V DC power-supply. The products need to be connected to the computer using two USB/jack cables or using one USB/jack cable to the computer and a jack/jack cable to the other product using the daisy chained functionality (Daisy-Out connector of a product to USB-In of the second).
