The laser driver LD-SMART is developed to operate our laser modules ELM1064, ELM1064HP as well as ELM532 and other. The driver contains up to three PID temperature controller to stabilize the temperature of the laser diode, the laser crystal as well as the frequency-doubling crystal. Via the LD-SMART, a laser diode can be driven within or apart from the driver and can be modulated driven in cw mode or pulsed. The modulation is made via the driver integrated clock generator or via external trigger signals. The external modulation can be achieved by an analogous or a TTL signal. To operate the driver via USB or Bluetooth, a user-friendly software is available.
