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

The fundamental principles of the operation of a solid-state laser are presented for the case when the active element is a thin disk. An analytical model of this laser is developed. The model is used to calculate the influence of the various paramete

Various pumping schemes for operating thin disk lasers are reported. Starting from quasi-end-pumping of one disk we will discuss how multiple absorption passes in the laser crystal can be realized by using iterative relay imaging. This concept can be

Results for the Nd: YAG thin disk laser are presented. An output power of 65 W is achieved with a two disk laser. Fundamental mode operation is possible at the expense of a reduced efficiency due to the strong and aspherical thermal lens. Using thinn

The thin disk laser design enables the operation of a quasi-three-level laser active medium, e. g. Yb:YAG, in the high power regime with high optical efficiency. This requires a high absorption efficiency, which is realized by multiple pump beam pass

A novel design for pumping the Yb:YAG thin disc laser is presented. By increasing the number of absorption passes from eight to sixteen the crystal thickness can be reduced to about 240 µm. With this setup an optical efficiency of η = 57. 7 % at an
