对于薄圆盘激光器，较大圆盘的自发辐射放大率的增加限制了可扩展性。放大的自发辐射对激发离子的有效寿命的影响的分析模型的开发，并与此模型优化的参数为最小化的寿命reductions.It示出的输出功率高达兆瓦级是可以实现的与一个单一的磁盘，但磁盘的尺寸远远超出了实际的技术限制。该模型还用于评估可实现的能量的限制。
For the thin-disk laser the increased amplification of spontaneous emission for larger disks limits the scalability. An analytical model of the influence of the amplified spontaneous emission on the effective lifetime of the excited ions is developed and with this model optimized parameters for the minimization of the lifetime reduction are found. It is shown that output powers up to the megawatt level are achievable with a single disk, but with disk dimensions far beyond the actual technical limits. The model is also used to evaluate the limits of achievable energy.
