Fast Modulated Drivers

Modulated - MCM

The Medium Current Modulator (MCM) can be used for CW-, modulated and pulsed operation.

The driver MCM also can be controlled only via hardware Interface.

It has two analog inputs and a trigger input as well as an internal pulse Generator and a BIAS set-point.

A CW-operation up to 40A and a short pulsed Operation up to 80A at a Diode voltage up to 46V is possible.

FM, VFS,VFM and MSM are especially designed for very fast modulation with arbitrary curves and for very short pulses. The maximum diode current for CW operation is 120A, for pulsed operation 240A at maximum diode voltages of 49V.

Fast Drivers - FM/VFM/MSM

The models FM, VFM and MSM are especially designed for very fast modulation with arbitrary curves and for very short pulses. The maximum diode current for CW operation is 120A, for pulsed operation 240A at maximum diode voltages of 49V. Depending on the whole configuration “laser driver – laser diode” a rise time of less than 10ns and a frequency of greater than 30MHz can be achieved.
  • A parallel operation for high-demand applications is possible.
