Abstract
A circuit arrangement for operating a laser diode in clocked mode includes a monitor photodiode, from the signal of which a measure of the radiation emitted by the laser diode is obtained as voltage to be measured, and a comparator, which compares the voltage to be measured with a reference voltage and provides the difference signal to a controller, wherein both the voltage to be measured and the reference voltage are applied continuously to the comparator. In order to carry out operation of the laser diode in clocked mode, a clocked-mode operation of the energy supply of the comparator is provided.
