Quick Start: Modulating a Laser Diode Driver
Most ILX Lightwave laser diode current sources and controllers have an external modulation input. The purpose of this technical note is to give a quick overview on setting up an ILX Lightwave laser diode controller for sine wave modulation. A more detailed discussion on modulation can be found in ILX Lightwave Application Note #22: Modulating Laser Diodes.For this technical note we will be using an ILX Lightwave LDC-3724B and Agilent Waveform Function Generator model 33120. Using the modulation function on the LDC-3724B is very similar to all other ILX Lightwave laser diode current source and controllers.
