在简单模型中考虑了放大自发辐射（ASE）、往返损耗和过热对功率的限制。优化的输出功率相对于泵浦区域的大小，其厚度和往返增益导致这些参数的标度律。在功率缩放的极限附近，往返损耗应该与期望输出功率的立方根成反比。这一预测与实验数据相吻合。使用厚的未掺杂层（抗ASE帽）允许在相同的往返损耗下增加一个数量级的可实现的最大功率。
Limit of power from amplified spontaneous emission (ASE), round-trip loss, and overheating is considered within simple model. The optimization of the output power with respect to size of the pumped region, its thickness and round-trip gain leads to the scaling laws for these parameters. In vicinity of the limit of power scaling, the round-trip loss should scale inversely proportional to the cubic root of the desired output power. This prediction agrees with the experimental data. The use of the thick undoped layer (anti-ASE cap) allows to increase for an order of magnitude the maximal power achievable at the same round-trip loss.
