摘要：
We design a set of processing devices to drill the shaped holes of turbine blades by using a femtosecond laser which outputs 1064 nm 5 W pulses at 100kHz,investigate the mechanism of the femtosecond laser interaction with metals,and demonstrate that ultrafast laser drilling has distinct strong points against electric spark and longer laser pulse processing.The advantages related to no recast layer,no thermal effect,no micro crack,high precision,and high processing efficiency are carried out.
