<p>The invention relates to a method for operating a pump light source (30) with a diode laser (31), which provides a pump light (28a), in particular for optically pumping a laser device (26). According to the invention, the pump light source (30) is driven in a first operating mode in such a way that the diode laser (31) assumes a predeterminable target temperature, which is in the region of a maximum of the absorption coefficient of the laser-active solid body (44) of the laser device (26). In a second operating mode which follows the first operating mode, the pump light source (30) is driven in such a way that it produces pump light (28a) in order to build up a population inversion in the laser-active solid body (44) of the laser device (26). In a third operating mode which follows the second operating mode, the pump light source (30) is driven in such a way that it produces pump light (28a) in such a way as to activate laser operation in the laser device (26), wherein the driving duration in the third operating mode is shorter than a driving duration in the second operating mode, and/or a drive current (i) in the third operating mode is higher than a drive current (i) in the second operating mode.</p> |
