A real-time hole depth diagnostic based on coherent imaging with plasma amendment during femtosecondlaser hole-drilling

An in-process coherent imaging diagnostic has been developed to real-time measure the hole depth during air-film hole drilling by a femtosecond laser. A super-luminescent diode with a wavelength of 830~13 nm is chosen as the coherent light source which determines a depth resolution of 12 {\mu}m. The...
