摘要：

Pump-saturation effects in end-pumped solid-state lasers are considered. In particular we investigate the influence of the pump beam width on both the laser threshold and the laser efficiency in four-level laser material. We demonstrate that, in contrast with the results obtained when pump saturation is neglected, a pure on-axis pumping does not ensure the lowest threshold and the highest laser efficiency. Pump-saturation effects lead to an optimum pump beam width for a fixed laser beam radius. (C) 1998 Optical Society of America.
