*Please note,
  that the rise and fall time and the pulse width may be prolonged by long cable between the power supply and the diode laser



All options are already included

Within this series, complete microprocessor controlled devices with integrated Peltier cooling boards are available
and an external input allows power stabilization as well. A RS232 interface allows the controlling of all parameters
by PC, e.g.
In addition, all DD units set the voltage automatically up to 3 or 6 V in dependence of the number of the used
diode lasers. So the DD can run one to two diode lasers simultaneously.



Intelligent Software

By internal Software the user has the choice to set all parameters and - if wanted - to set a time limit for the
current. In addition, for pulsed operation the pulse width and the pulse period can be choose by the menu for
the internally generated top hat pulses.



Analogue modulation
(only 50 A version)

An external analogue modulation input allows precision control of the laser output for a variety of applications.
So, by external modulation, sinusoidal, triangular or other pulse shapes are possible.
