本文将阐述薄板激光器设计的基本思想，并说明不同激光材料的优点。连续波和调q操作以及短脉冲（ns）和超短脉冲（ps, fs）放大的结果证明了薄板激光器设计的潜力。该激光器设计的标度规律表明，单盘工作时的功率极限远远超过10kw，单盘工作时的能量极限高于1j。此外，还将讨论薄板激光器概念在光泵浦半导体结构中的适用性。当泵浦光子直接进入量子阱时，泵浦光子与激光光子之间的能量缺陷可以小于5%，从而减少了半导体结构内部产生的废热。初步结果证明了这一新概念的潜力。最后，对薄板激光技术的工业实现进行了简要概述。
The principle ideas of the thin disk laser design will be illustrated and the advantages for operating different laser materials will be explained. The results for cw- and q-switched operation as well as for amplification of short (ns) and ultra-short (ps, fs) pulses demonstrate the potential of the thin disk laser design. The scaling laws for this laser design show that the power limit for cw-operation is far beyond 10 kW for one single disk and the energy limit is higher than 1 J from one disk in pulsed operation. Also the applicability of the thin disk laser concept to optically pumped semiconductor structures will be discussed. When pumping directly into the quantum wells the energy defect between pump- and laser photon can be smaller than 5% thus reducing the waste heat generated inside the semiconductor structure. First results demonstrate the potential of this new concept. Finally, a short overview of the industrial realization of the thin disk laser technology will be given.
