航空发动机冷却孔的打孔一直是激光器在航空工业中的一个主要用途。然而,采用先进的工程设计,目前已要将商业用固体和气体激光系统的“零件对零件”和“孔对孔”重复精度达到其性能的极限(无法进一步提高)。 最近,美国通用电气(GE)航空发动机公司开发出的一种面抽运(片状)激光器打孔装置有可能使激光束质量优于通常的固 Drilling of aero-engine cooling holes has been one of the major uses of lasers in the aeronautics industry. However, with advanced engineering designs, the “part-to-part” and “hole-to-hole” repeatability of commercial solid and gas laser systems is now at the limit of its performance (no further improvement). Recently, a surface pumped (chip) laser perforation device developed by GE Aviation Company has the potential to make laser beams of better quality than conventional solid
