摘要：

Input-output characteristics and multimode oscillation properties have been investigated in laser-diode-pumped microchip LiNdP4O12 lasers under different pump-beam focusing conditions, using microscope objective lenses with varying magnifications. The lasing threshold and slope efficiency, as well as the number of oscillating modes, are shown to depend on the pump-beam radius. The results are explained in terms of the pump-radius-dependent thermal lens effect and the Auger recombination process in high-density pumping regimes.
