导出了固体激光器光泵浦下吸收饱和因子的新模型，这些因子取决于泵浦方案。我们研究了Nd:YVO/ sub4 /中的泵浦饱和效应，发现直接泵浦方案中由于基态能级的耗尽而导致的泵浦吸收漂白比传统的四能级泵浦方案更有效。然而，通过激光可以恢复饱和效应。
Novel models for the saturation factors of absorption under optical pumping in solid-state lasers are derived, and these factors depend on the pumping scheme. We investigated the pump saturation effect in Nd:YVO/sub 4/ and found that the bleaching of pump absorption due to the depletion of a ground-state level in a direct pumping scheme was more effective than that in a conventional four-level pumping scheme. However, the saturation effect was recovered by lasing.
