description The invention relates to a method for the highly precise regulation of load-variable heat sources or heat sinks, and to a device for controlling the temperature of a dynamic heat source, especially of pump diodes for solid-state lasers. According to said method, the calculated mean value of the forward flow temperature and the return flow temperature is preset as an actual value for regulating the power, in order to ensure a stabilization of the heat source even without any information on the type of thermal load and the heat quantity to be dissipated, by the mean reference temperature for the heat flow to or from the temperature-controlling medium being maintained at a constant value irrespective of the heat quantity to be dissipated. As far as the device is concerned, a return flow temperature measuring device is provided in addition to a forward flow temperature measuring device arranged in the pump diode coolant circuit, both measuring devices being connected to an analog or digital computing unit which performs a mean value calculation in order to determine a refrigerating capacity set value transmitted to corresponding switching devices for the regulation of the load.
