This laser diode driver & temperature controller allows fully independent control of up to 8 laser diodes from CW down to very short pulses. It includes several functions such as one pulse generator and one very low noise current and modulation driver per laser diode.

This Laser Diode Driver is a precision module able to drive simultaneously and independently several laser diodes in any operating regime. The current level ranges up to 4 A in pulse regime and 2.5 A in CW with a current resolution down to 0.05 mA. Whereas it is often used for fiber coupled laser diodes, it is also compatible with any type of laser diode form factor.  It is controlled by an easy-to-use graphical interface and contains more than 6 connectors per laser diode for various external analog input/outputs signals.

multi channel laser diode driver 5ns pulse performance
5 ns pulse shape at 4 A with a butterfly laser diode

Multi channel laser-diode-driver KEY FEATURES :

  • From CW (Continuous Wave) down to 1 nanosecond pulse duration
  • Extremely low noise and ripple
  • Fully independent control of CW/Pulse duration, Peak/CW powers, Pulse rep rate, Compliance voltage, Pulse overshoot, Chip temperatures
  • Zero insertion force mounting sockets for any Butterfly or others form factors (TOSA etc.)
  • Fiber management with optical power sink
  • Several photodiode inputs for full optical power control when needed
  • USB & analogue voltage signal remote controls
  • Multiple Libraries (Labview VIs, DLLs, Hexa, Python etc.)

 

This Multi channel laser-diode-driver  works alone or in series with other products in our range like :

 

Complex systems, such as Multidiode gas sensing or Multidiode imaging, can be quickly developed with this multi channel laser diode driver platform using laser diodes like Eblana, Nanoplus or NTTelectronics.

This laser diode driver product is part of our “Multiboard” laser driver and synchronization modules family.
