薄圆盘激光器是准三能级激光激活介质在高功率区高光学效率运转的最佳激光器设计。激光器输出功率的数值计算表明，在室温下利用16次吸收通过，具有高达1 kW的输出功率和50%以上的光学效率的操作是可能的。输出功率的缩放可以通过使用一个或多个盘缩放泵浦面积来实现。实验结果表明，在冷却水温度为15/spl deg/C时，单晶体的最大输出功率为647 W，光效率为51%;四晶体的最大输出功率为1070 W，光效率为48%。
The thin disc laser is presented as an optimal laser design for the operation of a quasi-three-level laser active medium in the high power regime with high optical efficiency. Numerical calculations of the laser output power show that operation with an output power up to 1 kW with an optical efficiency of 50% and more is possible at room temperature utilizing 16 absorption passes. Scaling of the output power can be realized by scaling the pumped area using one or more discs. The experimental investigations yield a maximum output power of 647 W at 51% optical efficiency for one crystal and of 1070 W with 48% optical efficiency for four crystals at a temperature of the cooling water of 15/spl deg/C.
