Methods and systems for laser processing a workpiece and methods and apparatus for controlling beam quality therein
摘要：
Laser processing methods, systems and apparatus having a super-modulating power supply or pumping subsystem and high beam quality (i.e., brightness) are disclosed. The methods, systems and apparatus have significant benefits, improved operation characteristics and material processing capability over currently available methods, systems and apparatus. In at least one embodiment, the beam quality of a high power solid state laser is improved in the presence of thermal lensing. High power laser cutting, scribing, and welding results are improved with a combination of modulation and high beam quality while providing for improved processing speeds.
摘要（中）：

公开了具有超调制电源或泵送子系统和高光束质量（即，亮度）的激光加工方法，系统和装置。 方法，系统和装置与现有的方法，系统和装置相比具有显着的益处，改进的操作特性和材料处理能力。 在至少一个实施例中，在存在热透镜的情况下，高功率固体激光器的光束质量得到改善。 通过调制和高光束质量的组合，提高了大功率激光切割，划线和焊接结果，同时提供了改进的处理速度。
