Abstract

We demonstrated an experimental study of the influence of the Nd 3+ concentration on scaling diode-pumped Nd:YVO 4 1.34-μm lasers to higher power. An output power of 5.1 W at 1.34 μm was obtained with a 0.5-at.% Nd-doped YVO 4 at 13.5 W of incident pump power. The strong dependence of the slope efficiency on the dopant concentration is attributed to an Auger upconversion process.

Abstract

We present a theoretical study of the single-mode operation in a diode pumped Nd:YVO4/KTP green laser by considering the combined action of the anisotropic emission cross-section of Nd:YVO4 and the KTP crystal acting as a birefringent filter. The influence of the KTP length on the performance of single-mode operation was investigated. Comparison between theoretical predictions and experimental results is presented.
