This technical note describes the results of output stability tests performed on a current production ILX Lightwave LDC-3724B laser diode controller. Two sets of data shall be presented. The first dataset includes voltage measurements taken from a temperature-stabilized, resistive load connected to the laser current source output to measure its stability. Also, resistance measurements from a thermistor embedded in a second Peltier-driven test load will be shown to demonstrate temperature control stability. The second dataset includes power and wavelength data from an actual laser diode connected to the controller to show how an active device performs under the same conditions.
