本文重点介绍了通快盘式激光器技术的最新进展。盘式激光器结合了独特的性能，特别是高输出亮度（在任何高功率平台的最低泵浦亮度要求），功率可扩展性和背反射不敏感性。在最新一代的连续波激光器中，工业产品中的一个圆盘可以提取6kW的光束质量，适用于切割和焊接。实验室的结果与高达4千瓦的激光功率在近衍射极限光束质量（M2=1.38）和8千瓦的光束质量为3毫米mrad从一个单一的磁盘和更高的输出功率水平与较低的光束质量。最后给出了倍频连续波圆盘激光器的实验结果。
This paper highlights the latest advances of disk laser technology at TRUMPF. The disk laser combines unique properties, especially high output brilliance (at the lowest pump brilliance requirements of any high power platform), power scalability and insensitivity to back reflections. In the latest generation of CW disk lasers, 6kW are extracted from one disk in an industrial product at beam qualities suitable for cutting and welding. Laboratory results with up to 4 kW laser power at nearly diffraction limited beam quality (M2=1.38) and 8 kW with a beam quality of 3 mm mrad from a single disk and even higher output power levels with lower beam quality will be presented. Finally, results of a frequency doubled CW disk laser will be shown.
