Multi-channel laser diode driver – CW or Pulsed – up to 8 channels
This laser diode driver & temperature controller allows full independent control of up to 8 laser diodes from CW down to very short pulses. It includes several functions including a pulse generator and a very low noise current and modulation driver.
This multi-channel laser diode driver is a precision module able to drive simultaneously and independantly 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 dedicated for fiber coupled laser diodes, it is compatible with any type of laser diode form factor.
The performances of this laser diode driver have been optimized to be compatible with many applicative constraints in term of noise, ripple, resolution, current and temperature ranges, Jitter etc.
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.
These products are now offered by AeroDIODE, 
a new ALPhANOV spin-off company. The product manager is available to answer any technical of commercial question.
