Abstract

The invention is directed to a cooling arrangement for a semiconductor pump source which develops heat during operation. The cooling arrrangement includes a heat sink defining a seat for accommodating the pump source thereon and a cooling channel is formed in the heat sink for conducting a coolant therethrough to remove a major portion of the heat. A Peltier device is connected to the heat sink for finely controlling the temperature of the heat sink so as to permit the semiconductor pump source to emit radiation having a predetermined optional wavelength.
