Laser connections

The CTL200-1 / CTL200-2 is compatible with Type 1 / Type 2 butterfly laser diodes. Note
that it is only compatible with floating diodes, which means that neither the anode nor
the cathode should be connected to the case.

Summary of Contents for Koheron CTL200

  • Page 1 Laser connections The CTL200-1 / CTL200-2 is compatible with Type 1 / Type 2 butterfly laser diodes. Note that it is only compatible with floating diodes, which means that neither the anode nor the cathode should be connected to the case.
  • Page 2 Power supply The board must be supplied with the 5.9 V / 3 A power supply that comes with the CTL200. Another power supply can be used, as long as the voltage is between 5.7 V and 6.5 V. Serial interface The serial interface can be accessed either via the micro USB connector or via the TX and RX pins of the programming connector.
  • Page 3 TEMP: Turns ON when the thermistor resistance is within 1 Ω of the setpoint. Modulation inputs The CTL200 has two current modulation inputs available on SMA connectors: DC modulation input for modulation between DC and 10 MHz. Modulation range is +/- 1 V.
  • Page 4 Thermal management The TEC voltage limits (vtmin and vtmax) and the thermistor resistance limits (rtmin and rtmax) provide an effective way of protecting the laser against thermal runaway. For reliable operation, the aluminium cooling base plate must be properly heatsunk.
