Influence of the laser-diode temperature on crystal absorption and output power in an end-pumped Nd:YVO4 laser

摘要

In this work, we studied the influence of heat loaded into the laser crystal in an endpumped solid-state Nd:YVO4 high power laser. We have shown experimentally that the optimum value of the laser-diode temperature for the maximum pump power absorption by the Nd:YVO4 crystal and the maximum Nd:YVO4 laser output power are approximately similar to that of a system of the low power type, but by increasing the pump power, different values can be obtained.
