Abstract

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.

Claim 1
Independent Claim 83 words
A cooling arrangement for a semiconductor pump source which develops heat during operation, the cooling arrangement comprising: a heat sink defining a seat for accommodating the pump source thereon; cooling channel means formed in said heat sink for conducting a coolant therethrough to remove a major portion of said heat; and, Peltier means connected to said heat sink for finely controlling the temperature of said heat sink so as to permit said semiconductor pump source to emit radiation having a predetermined optional wavelength.
Claim 2
Dependent Claim 83 words
A cooling arrangement for a semiconductor pump source which develops heat during operation, the cooling arrangement comprising: a heat sink defining a seat for accommodating the pump source thereon; cooling channel means formed in said heat sink for conducting a coolant therethrough to remove a major portion of said heat; and, Peltier means connected to said heat sink for finely controlling the temperature of said heat sink so as to permit said semiconductor pump source to emit radiation having a predetermined optional wavelength.
Claim 3
Dependent Claim 49 words
The cooling arrangement of claim 1, said Peltier means including a Peltier element mounted on said heat sink; temperature sensor means mounted on said heat sink for detecting the temperature thereof; and, control means for controlling the supply of current to said Peltier element in dependence upon said temperature.
Claim 4
Dependent Claim 25 words
The cooling arrangement of claim 1, further comprising: a base plate connected to said Peltier means; and, ancillary cooling means for cooling said base plate.
Claim 5
Dependent Claim 177 words
