Zusammenfassung:For a diode pumped solid-state laser, measures to improve the pump light absorption in anisotropic crystals are proposed. The proposed measures reduce the dependency of the pump light absorption on the diode current and the diode temperature as well as on the detuning of the pump diode from the absorption line. These measures include sending the pump radiation twice through the crystal, placement of the laser crystal in an orientation that does not exhibit the optimum absorption and the use of a retarder.
